2001-248670 : BRAKE DEVICE FOR BUGGY VEHICLE
  PROBLEM TO BE SOLVED: To satisfy all the items of high ground clearance, excellence in dustproof and waterproof properties, good cooling character, and further, the sure simultaneous braking of right and left wheels. SOLUTION: A first and a second brake shaft 38L, 38R acceleration driven respectively by a left and a right differential output shaft 29L, 29R in a pair and a first and a second brake 42L, 42R capable of giving brake force to the respective brake shafts 38L, 38R are arranged in a reduction case 16, so as to cool these brakes 42L, 42R by lubricating oil in the reduction case 16, 17.

H11-270579 : MULTI-DISK TYPE FRICTION CLUTCH
  PROBLEM TO BE SOLVED: To invariably apply stable elastic force to adjacent friction disks even when a return spring receives large centrifugal force by using a plate-like spring fixed to a coupling lug as the return spring provided between the drive friction disks. SOLUTION: Many hook grooves 22 extending in the axial direction are provided on the circular barrel section 21 of a clutch outer 15, and many drive friction disks 30 are coupled by coupling lugs 30a provided on the outer periphery movably in the axial direction only. A return spring 35 is inserted and fixed from the outside of the coupling lug 30a formed on the outer periphery of each friction disk 30. The return spring 35 acts in the direction to separate adjacent friction disks 30. The return spring 35 is made of a quenched steel sheet, it is provided with a U-shaped main body 35a and blade sections 35b, 35b obliquely extending from the main body 35a, and a coupling pawl 35c provided on the main body 35a is coupled with a small hole 30b formed on the coupling lug 30a as a release stop. The return spring 35 hardly receives the effect of the centrifugal force by rotation, and the elasticity for separating the friction disks 30 from each other is stabilized.

H11-029013 : BRAKING DEVICE FOR BUGGY
PROBLEM TO BE SOLVED: To brake the rear wheels of a buggy with reliability by producing sufficient braking force of a braking device even when the device is reduced in diameter to further heighten a ground clearance. SOLUTION: A wet braking device 43 comprises a plurality of rotatable friction brake disks 48 coupled to the input shaft 24 of a reduction gear 23 connected to a propeller shaft 21 for their axial free slide and against their relative rotation, a plurality of stationary friction brake disks 47 alternated with the rotatable friction brake disks 48, an unrotative brake housing 16 for enclosing both those friction brake disks 48 and 47 so that the stationary friction brake disks 47 are supported for their axial free slide and against their rotation, pressure receiving parts 49 arranged in the housing 16 to support one side of both those friction brake disks 48 and 47, and an actuation means 50 to press the other side of both those friction brake disks 48 and 47 toward the pressure receiving parts 49.

H10-122258 : TRAILING PREVENTION DEVICE OF WET TYPE MULTI-PLATE CLUTCH
PROBLEM TO BE SOLVED: To prevent any trailing surely by providing a spring member provided with a holding part for holding the outer edge of a friction plate and an elastic piece extending to a periphery direction and deformable to a surface direction. SOLUTION: A spring member 40 is a sheet spring formed by hardening after pressing a steel plate and composed of a holding part 41 for installing by holding the outer edge part of a first friction plate 33a and an elastic piece 42 rangingly arranged adjacent to the holding part 41. The elastic piece 42 is a spring for pulling apart between the first friction plate 33a and a push-press plate and a pressure receive plate. When the holding part 41 of a spring member 40 is held from an outside to the projection part A of the first friction plate 33a, a base part 41a is engaged with a four-sided figure recessed part 34 provided on the projection part A and a reverse stop claw 43 is engaged with a small diameter through hole 35 and fixed. Thereby, the spring member 40 can be fixed stably.

H08-164867 : LUBRICATING DEVICE FOR MULTIPLE DISC CLUTCH
PURPOSE: To provide a switch valve system simple in structure to cut off oil feeding once at the time of cutoff operation of a multiple disc clutch in a lubricating method to feed oil to an inner surface of a friction plate of the multiple disc clutch. CONSTITUTION: A sliding element 6c to cut and connect a multiple disc clutch provided on a power transmission shaft is provided, a supplying oil passage 8b connected to a hydraulic pressure source is formed on the sliding element and a switch valve to be opened and closed in accordance with advance and retreat of the sliding element is constituted between an oil passage 8a provided on the power transmission shaft and the supplying oil passage 8b provided on the sliding element in the multiple disc clutch constituted free to feed and cut off lubricating oil by providing the oil passage 8a to lubricate a friction plate on the power transmission shaft to support the multiple disc clutch 5 and providing an opening and closing valve in the oil passage 8a. Additionally, it id devised to feed oil and stop it in accordance with movement of the sliding element 6c to advance to and retreat from the multiple disc clutch 5.

H07-233827 : STEERING BRAKING CLUTCH FOR SMALL TYPE TRAVELING AGRICULTURAL MACHINE
PURPOSE: To accurately and inexpensively provide a device which can carry out a function to cut off power and a function to actuate a brake in order at extremely short time difference by only one operation in the braking clutch of a traveling agricultural machine. CONSTITUTION: A steering retarder 30, a steering clutch 40 and a pressing member 50 to actuate those devices are arranged in order on a supporting shaft 20, and a function ball bearing is provided in the pressing member 50. In addition, the outer ring is opposite to an actuating means for the steering retarder 30, and an inner ring 52b is opposite to an actuating means for a steering clutch 40, which is composed of the inner cylinder 34 of the steering retarder 30.
