。 In a camshaft rotation drive device for transmitting engine rotation to a camshaft, a part of the rotation transmission system from the engine to the camshaft includes an engine-side driving member coaxially rotatable relative to each other, and a camshaft-side driven member. One of these has a spring and a pin movable in the radial direction against the spring, and the other has a groove that engages with the pin in an appropriate range in the radial direction corresponding to the movement range of the pin. and the shape of the groove is configured such that as the pin moves outward in the radial direction, the rotational phase of the driven member relative to the driving member gradually shifts in the rotational direction of the driving member. Camshaft rotation drive device.
