Claims

[Claims for Utility Model Registration] (1) A sliding gear 5 for a gear sliding type transmission is slidably supported, and the sliding gear 5 is slidably supported at a position where the sliding gear 5 meshes with a fixed gear. A detent mechanism that locks movement is protruded from inside the shaft directly on the shaft on which the sliding gear 5 is slidable, or on a shaft on which the shifter 4 on which the sliding gear 5 is slidable is slidable. A cylinder chamber is formed in the shaft in which the detent ball 3 is fitted, and one end of the cylinder chamber is formed in the shaft in which the detent ball 3 is fitted. A press piston 2 to be brought into contact is slidably provided, a biasing spring 8 is provided for biasing from the other end of the press piston 2, and a cylinder chamber housing the biasing spring 8 is configured as an oil chamber to maintain hydraulic pressure. A detent mechanism for a gear sliding type transmission, characterized in that it is configured to increase the detent force of the detent ball 3 by introducing pressure oil of the operating type transmission. (2) A cylinder chamber is formed on the opposite side of the detent ball 3, facing the pressing piston 2 described in claim 1 of the utility model registration claim, and a second pressing piston 7 is provided.
is slidably provided, and the second pressing piston 7 is configured to increase the pressing force of the second pressing piston in contact with the detent ball 3 in conjunction with the braking of the steering brake of the transmission. A detent mechanism for a gear sliding type transmission.
