Claims (1)

[Claims for Utility Model Registration] (1) Transmit the operating force of the change lever to a shift cable and a select cable, select a desired shift fork by operating the select cable, and select the selected shift fork by operating the shift cable. In a gear shift operation device for a gear transmission that is configured to shift, one end is connected to a shift cable and a select cable, and a switching lever shaft that moves in the axial direction when a select operation is performed and rotates when a shift operation is performed; A switching lever is fitted and fixed, and one end selectively engages with the fork head to transmit the movement of the switching lever shaft to the fork head. The switching lever support is inserted through the switching lever support movably and engages with other fork heads disposed on both sides of the switching lever that are not engaged with the switching lever, and is fitted to be rotatable relative to the switching lever shaft. , an interlock plate whose rotation is restricted relative to the switching lever support, a return spring inserted through the switching lever shaft and elastically supporting the switching lever and interlock plate in a neutral position, and a switching lever support parallel to the switching lever shaft. A restricting shaft whose both ends are supported by the left shaft, and a restricting shaft which is inserted into the left shaft so as to be slidable in the axial direction and rotatable at a certain angle, and which is in contact with the end surface of the switching lever and located on the same shift operation line. It is equipped with a restrictive cam that restricts the shift operation from forward gear to reverse gear, and a torsion spring that is inserted through the restrictive shaft and biases the restrictive cam in the direction of engagement with the switching lever. A speed change operating device for a gear transmission, characterized in that it is integrally assembled with a switching lever support. (2) In the speed change operation device for a gear transmission according to claim (1), a storage part with an open top is formed above the oil level of the transmission case, and all parts including the switching lever are placed in the storage part. The assembled switching lever support is stored, and a lid is removably attached to the storage part, one end of the switching lever shaft projects from the lid, and a cable is connected to the projecting end. A speed change operation device for a gear transmission. (3) In the speed change operation device for a gear transmission according to claim (2), the ends of the switching lever shaft and restricting shaft protruding from the switching lever support are provided on the bottom surface of the housing part of the transmission case and the bottom surface of the lid. 1. A speed change operation device for a gear transmission, characterized in that a support hole is provided to fit into the support hole, and a lock bolt is inserted into the lid, the tip of which is screwed into a switching lever support. (4) A gear transmission that transmits the operating force of the change lever to a shift cable and a select cable, selects a desired shift fork by operating the select cable, and shifts the selected shift fork by operating the shift cable. In a speed change operation device, one end is connected to a shift cable and a select cable, and is fitted and fixed to a switching lever shaft that moves in the axial direction when a select operation is performed and rotates when a shift operation is performed. A switching lever that selectively engages with the fork head to transmit the movement of the switching lever shaft to the fork head, and a switching lever that is attached to the transmission case and into which both ends of the switching lever shaft are inserted so as to be movable in the rotational and axial directions. The switching lever is provided with a protrusion for a stopper, and the switching lever support is formed with a stopper hole into which the protrusion is loosely fitted. A gear transmission operating device for a gear transmission, characterized in that a select range and a shift range are defined. (5) In the gear transmission operating device according to claim (1), the gear is characterized in that the switching lever support is provided with a stopper surface that defines the initial position of the restricting cam in the rotational direction and axial direction.
