ABSTRACT:
A gear transmission mechanism includes main transmission gearing and auxiliary transmission gearing. Main transmission gearing transmits the movement of a shift lever in a shift direction through a shift mechanism and a fork head to a sleeve, and auxiliary transmission gearing can select a high or low speed ratio in response to transmission of the movement of the shift lever to another sleeve when the shift lever is shifted from a neutral position in one shift direction or the other. The shift mechanism comprises an input member, a reversing mechanism, a reversing member, and a pair of shift heads, the input member coacting with the shift lever such that the movement of the shift lever in the shift direction results in the movement of the input member in a shift direction. The reversing mechanism is interposed between the input member and the reversing member for reversing the movement of the input member in the shift direction into movement in an opposite shift direction and for transmitting the reversed movement to the reversing member.
