摘要： A multiplate friction clutch includes: a pressure plate having a boss portion which penetrates a clutch center; a clutch lifter plate joined to the boss portion and receiving a drive force in a axial direction at a time of disconnection between a friction plate and a clutch plate; and a spring sandwiched between the clutch lifter plate and the clutch center, and capable of generating an elastic force in a direction that the friction plate and the clutch plate are pressed to each other. A position restricting portion is provided on the clutch lifter plate, the position restricting portion being brought into contact with the boss portion from an outside in a radial direction of the clutch lifter plate so as to restrict a position of the clutch lifter plate with respect to the pressure plate.

摘要： A transmission for a vehicle has a main shaft and a counter shaft, which are supported in a transmission case by bearings. Gears on the main shaft and gears on the counter shaft include: shifter gears which are not rotatable but axially movable relative to the shaft, and fixed gears which are rotatable but not axially movable relative to the shaft. Dog clutches are provided between the shifter gears and the fixed gears, and outer races of the bearings supporting the main and counter shafts are affixed to the transmission case. Vibration-absorbing elastic members are pressed against the outer races from axially outside and are set to have a volume of 50% or more of the volume of the outer races. With such configuration, the vibration of the bearings supporting both the main and counter shafts of the transmission is attenuated, and striking noise caused by shifting is reduced.

摘要： A variable speed drive wherein an impact to be transmitted to an inputting mechanism is absorbed. A shift spindle has an input side end portion to which an inputting mechanism is connected and an output side end portion supported for rotation at a transmission side supporting portion provided on a transmission case. A master arm is positioned between the input side end portion and the output side end portion in an axial direction of the shift spindle. An extension collar member is fixed integrally to the master arm. The extension collar member connects the master arm and a connection portion provided at a location of the shift spindle rather near to the input side end portion than the output side end portion. The extension collar member extends from the connection portion toward the master arm with a gap left from an outer circumferential face of the shift spindle.
