PURPOSE:To make the device compact and lightweight by providing an air cylinder on the axial line to make a pinion carrier in the conventional device unnecessary, and to compose the air cylinder in a small capacity. CONSTITUTION:A bevel gear mechanism is composed of an input gear 61b provided at an input shaft 61, a pinion 66 pivoted at a casing 63A, and an output gear 67. And a slider 65A to hold the output gear 67, spline-sliding to an output shaft 62, and rotatable and slidable to the input gear 61b and the output gear 67 is housed therein. And while a same phase clutch 65b and a reverse phase clutch 65c connected to a same phase clutch 61c of the input gear 61b and a reverse phase clutch 67b of the output gear 67 are provided to the slider 65A, the slider 65A is composed to link an air cylinder 70 provided on the axial line. |
