PURPOSE:To improve the connection strength between a clutch hub and a shaft by freely coupling an inner cone with a hub section formed on a gear and freely coupling it with a clutch hub relatively rotatably by a predetermined value in a double-cone type synchronizing device. CONSTITUTION:A gear type transmission is provided with a first-fifth speed gear device between an input shaft and an output shaft 8 and is provided with a first-second speed synchronous engaging device 26 between gears 16, 17 of this gear device. In this case, the first-second speed synchronous engaging device 26 is provided with an inner cone 39 freely coupled with the hub section of the gears 16, 17 freely coupled with the output shaft 8 and an outer cone 41 arranged between a gear spline 38 and a clutch hub 37. A double cone 42 rotatable together with the gears 16, 17 and movable in the axial direction is arranged between both cones 39 and 41 so that the double cone 42 can be friction-coupled with the inner cone 39 via a synchronizer key 40 by the axial shift of the outer cone 41. |
