Claim:
A cam slider shock absorbing member configured to be provided in a cam device mounted on a fixed die and a movable die moving upward and downward to be provided for machining of a press-formed product, the cam device including a cam driver secured to one of the dies, a cam slider provided on the cam driver and configured to move in a predetermined direction by the cam driver, and a cam slider supporting base secured to the other die and configured to slidably support the cam slider, the cam slider having a resilient member configured to restore the cam slider to an original position following a cam action, wherein the shock absorbing member is configured to be mounted in a mounting hole formed in a one-side supporting strip of the cam slider supporting base, the shock absorbing member being configured to alleviate an impact generated when the cam slider is returned to the original position, the shock absorbing member having: a mounting portion formed to have an external dimension at least larger than an internal dimension of the mounting hole on the side of a lower end thereof so that the mounting portion can be press-fit in the mounting hole; and a deflecting portion having an external dimension smaller than an external dimension of the mounting portion, and being configured so that a predetermined distance is provided as a deflecting margin between the deflecting portion and an inner wall surface of the mounting hole on the upper side of the mounting portion, and so that an upper end of the deflecting portion projects upward from an opening end of the mounting hole and being formed to have a height which secures a length corresponding to a stroke to be compressed, and the upper end of the deflecting portion being pushed down to the same level as the opening end of the mounting hole when the cam driver presses against the open end of the mounting hole.
