PURPOSE:To make the device compact and lightweight and to simplify the structure by composing the device to slide a slider in the axial direction to convert the mode. CONSTITUTION:A bevel gear mechanism is composed of an input gear 61a provided on an input shaft 61, a pinion 66 pivoted at a casing 63A, and an output gear 67, and a slider 65A to pivot the output gear 67 and rotatable and slidable to the input gear 61a and the output gear 67 is provided. And the system is composed to provide a same phase clutch 65Aa and a reverse phase clutch 65Ab connected to a same phase clutch 61b of the input gear 61a and a reverse phase clutch 67b of the output gear 67, to provide a slidable shaft spline 92 fixing to the slider 65A through a spline 62a of an output shaft 62, and at the same time, to provide a piston 73 as a driving device to reciprocate through a shift fork 90 to the shaft spline 92. |
