ABSTRACT:
In a phase adjustment fixing apparatus for a cam, a cam fixing shaft is supported by a frame to freely move and has a clamp for clamping a cam at one end portion. A pressure unit is slidably supported on the cam fixing shaft and has a slidably supported lever. A spring member is interposed between the other end portion of the cam fixing shaft and the pressure unit. A sliding element is arranged at a swinging end of the lever to slide on a surface of the frame. An actuator swings the lever to move the sliding element between a cam fixing position where the sliding element slightly goes across a dead center and a cam fixed state releasing position where the sliding element largely comes across the dead center. A dead center is a position where the sliding element crosses a center line of the cam fixing shaft. At the cam fixing position of the sliding element, the pressure unit slides toward the other end portion of the cam fixing shaft to bias the cam fixing shaft in a direction to fix the cam through the spring member, and at the cam fixed state releasing position of the sliding element, the pressure unit releases a biasing force from the cam fixing shaft through the spring member.
