AUTOMATIC ROTATION SETTING MECHANISM FOR ENGINE AND OUTPUT SHAFT AT GEAR SHIFT OF MANUAL TRANSMISSION VEHICLE

PROBLEM TO BE SOLVED: To automatically provide appropriate engine speed until a clutch is engaged since shifting is changed by operating an angular swing arm through operation of a hydraulic piston so as to change shifting through a rotation setting gauge, and simultaneously operating a throttle wire through a moving body. SOLUTION: A gear pump is housed in a transmission main body, oil pressure generated therein is led to a piston 26, and hence an angular swing arm 29 is operated against a spring 27. The top 33, the third 34, the second 35, and the low 3b of an arm for gauge are rectilinearly welded to a fulcrum shaft 30 so as to constitute a rotation setting gauge, levers 41-44 are welded to the fulcrum of a moving body operating arm engaged with the gauge, and one ends of wires 53-56 are respectively combinedly fitted to the respective levers. The other end sides of the respective wire 53-56 are combinedly fitted to respective pistons for the top, third, second, and low. By motion of the moving body operating arm, a moving body 58 is displaced, so as to control a throttle through a throttle wire 59.
