摘要： A gear synchronizer assembly includes a clutch sleeve formed at its inner periphery with an internal radial projection, and a radially contractible annular resilient member supported by engagement with the inner circumference of an outer cylindrical hub portion of a hub member fixed to a transmission shaft. The resilient member has an axial leg extending therefrom toward the internal radial projection of the clutch sleeve and having a radial projection which is arranged to be engaged with the internal radial projection in shifting operation of the clutch sleeve toward a spline piece and arranged to abut against and urge a synchronizer ring toward the spline piece upon engagement with the internal radial projection of the clutch sleeve thereby to effect frictional engagement between the synchronizer ring and spline piece. The annular resilient member is further formed with at least one retainer lug which extends therefrom in an axial direction toward an annular body portion of the hub member and inserted into an axial hole in the annular body portion of the hub member to retain the resilient member in place in a circumferential direction.

摘要： In a change-speed gearing unit, a manual shift lever is mounted at its lower end on a retainer casing which is secured at its outer peripheral portion to the upper seating face of an extension housing for the unit by means of fastening bolts threaded into the housing with intervention of an oil buffer member of elastic material between the outer peripheral portion of the casing and the upper seating face of the housing. A first plurality of fastening bolts adjacent to the lower end of the shift lever are directly engaged with the outer peripheral portion of the retainer casing to prevent floating of the casing, and a second plurality of fastening bolts are engaged respectively through a plurality of elastic members with the outer peripheral portion of the casing such that the casing is floatably secured in place due to resiliency of the oil buffer member.

摘要： A die-cast transmission extension housing has an outer peripheral wall or whell and an integral bearing supporting partition wall provided transversely of the longitudinal axis of the shell between the open forward end and the closed rear end thereof. The partition wall supports at least a bearing for the transmission output shaft extending through the open forward end, the bearing on the partition wall and the closed end. The inner surfaces of the shell forwardly of the rear surface of the partition diverge to the open end of the shell so that the inner space defined by these inner surfaces and the partition can be moulded by a die-casting mould part which is slidable out of the inner space through the open end of the shell after the extension housing is die-cast. The upper wall of the extension housing is formed therein with an upper opening adapted to be closed by a shift lever retainer. The side and bottom walls of the shell cooperate with the partition wall to define a second inner space which is so shaped as to be moulded by another die-casting mould part which is slidable out of the second inner space through the upper opening after the extension housing is die-cast.
