SHIFTING OPERATION DEVICE

PROBLEM TO BE SOLVED: To provide a shifting operation device to be applied to an automated gear transmission, particularly, to a geared transmission having a plurality of clutches connected to one another for shortening a shifting time in predetermined shifting operation. SOLUTION: The shifting operation device comprises a plurality of shift grooves 13-15 formed in an inner lever 12 and opened around a shaft, and a plurality of shift fork heads 16-19 arranged at mutually predetermined intervals around the shaft. The plurality of shift grooves 13-15 are formed in the inner lever 12 and opened around the shaft for meshing with the predetermined shift fork heads 16-19 depending on a shift stage and for cancelling the meshing with the predetermined shift fork heads 16-19 being relatively moved around the shaft with select operation. The plurality of adjacent shift grooves 13, 14 and 14, 15 are mutually arranged at an interval equivalent to a shift stroke along the axial direction. COPYRIGHT: (C)2007,JPO&INPIT
