A pair of gears are provided on input and output shafts always in mesh with each other. A synchronizer for synchronizing the two gears comprises an inner cone whih has a tapered outer surface and is rotatably fitted on a hub portion and is in engagement with the clutch hub to permit rotation of the inner cone relative to the clutch hub by a predetermined amount. An outer cone has a tapered inner surface opposed to the tapered outer surface of the inner cone, and is adapted to be engaged wth the hub sleeve by way of splines to be rotated together when the hub sleeve is slid into engagement with the gear spline. A double cone is disposed between the inner surface of the outer cone and the outer surface of the inner cone and is supported for rotation together with the other gear and for sliding movement in the axial direction of the gear. |
