変速機の中立位置決め装置。[Claims for Utility Model Registration] 1. A detent rotor 3 is connected to the swash plate shaft 2, and the detent rotor 3 is operated by operating the speed change lever 8.
A device provided in a continuously variable forward/reverse transmission 1 which rotates a swash plate shaft 2 through a swash plate shaft 2, thereby performing continuously variable forward/reverse transmission, when the detent rotor 3 is in a neutral position. The detent rotor 3
and locks the rotation of the gear shift lever 8.
1. A neutral positioning device for a continuously variable forward/reverse transmission, characterized in that it is constructed by providing a lock mechanism 15 for moving the forward/reverse continuously variable transmission in a direction different from the forward/reverse operating direction. 2. The lock mechanism 15 includes a lock pin 19 that engages with the groove 7 formed on the outer periphery of the detent rotor 3, a spring 20 that presses the lock pin 19 against the outer periphery of the detent rotor 3, and the shift lever 8. A neutral positioning device for a forward/reverse continuously variable transmission according to claim 1), characterized in that the device includes a wire 22 that connects the lock pin 19 to the lock pin 19.
