PURPOSE: To minimize decrease of the effective area of an inner coupling toothing. CONSTITUTION: A ring-like coil spring element 21 which is held by a synchronizer ring 13 and closed in a peripheral direction can be elastically deformed centripetally relative to the rotation axis of a shaft supporting a gear 27 by an inclined surface 22 on teeth of an inner axial coupling 18 toothing of a shift sleeve 1 for the purpose of building up shifting and synchronizing forces. |
