PURPOSE:To cope with a variation of a working angle without replacing a cam unit, by constituting a cam unit having a structure which pushes out a sliding cam by supporting one end of a pressure receiving link plate by a universal joint fitted to a freely slidable sliding cam, and depressing the other end along the inclined face of a slant face cam. CONSTITUTION:A universal joint 20 is fitted to a sliding cam 17 supported by a cam guide 16 so as to be freely slidable. Subsequently, one end of a pressure receiving link plate 24 is supported freely rotatably by the universal joint 20. Subsequently, the other end of the pressure receiving link plate 24 is placed on the inclined face of a slant face cam 25, the other end is made to descend by a cam driver 27, the sliding cam 17 is pushed out, and a work 4 is worked by a working tool 10. Accordingly, even if the working angle is changed, it can be solved by only changing an inclined angle theta of a cam unit 6. |
