PROBLEM TO BE SOLVED: To provide a cam shift device which can reduce a driving force of an actuator.SOLUTION: A cam piece 20 is disposed to be axially reciprocable with respect to a camshaft 13, and is constituted of a first cam 22, a second cam 25, a first guide 31, and a second guide 36. An actuator 43 moves a first arm 41 and a second arm 42 in an axial direction of a shifter shaft 40. The first arm 41 is slidable along the first guide 31 and the second arm 42 is slidable with the second guide 36. A first inclination surface 32 provided to the first guide 31 and a second inclination surface 37 provided to the second guide 36 are disposed in a range where they are not overlapped with the first arm 41 and the second arm 42 when seen from an axial direction, while a first nose 24 and a second nose 27 are slid along a rocker arm 11. Therefore, when the actuator 43 moves the shifter shaft 40 in the axial direction, the cam piece 20 moves in the axial direction. |
