Abstract

An electromagnetic drive device includes a through-hole, through which a rod is received, and the rod includes an outer wall surface that is slidable relative to the through-hole. A clearance, which is measured from the outer wall surface of the rod placed in a maximum projected position to an inner wall surface of the through-hole, is smaller than a clearance, which is measured from the outer wall surface of the rod placed in a maximum retracted position to the inner wall surface. Therefore, a retracting-time clearance becomes relatively large, and thereby a frictional force between the rod and a support tubular portion can be reduced. Furthermore, a projecting-time clearance becomes relatively small, and thereby the amount of swing of a distal end of the rod in a radial direction can be reduced.
