速機の中立位置戻し装置。[Claims for Utility Model Registration] 1. A detent rotor 11 is connected to the trunnion shaft 9, and the trunnion shaft 9 is rotated via the detent rotor 11 by operating the speed change lever 14, thereby eliminating the need for forward and backward movement. A neutral position return device for a forward and backward continuously variable transmission 2 configured to perform step-change speeds, the device comprising:
The forward and backward continuously variable transmission is characterized in that the forward and backward continuously variable transmission 2 is provided with a neutral position return mechanism 10 that rotates the detent rotor 11 to the neutral position when a neutral pedal 26 is depressed. Machine neutral position return device. 2 The neutral position return mechanism 10 has one end rotatably pivoted, an intermediate portion engaged with a long hole at a position eccentric from the center of the detent rotor 11 by a predetermined distance, and the other end connected to the neutral pedal 26. a return link 16 that engages with a long hole in a link 23 that is connected to a wire 27 leading out from the detent rotor 11; Utility model registration claim 1) characterized in that the transmission arm 13 is connected to the wire 27, and the intermediate portion of the speed change arm 13 is engaged with another link 22 connected to the wire 27 through a slotted hole. A neutral position return device for a continuously variable forward/reverse transmission as described in 2.
