Abstract
A lifter includes a roller caused to abut against a cam thereby to be pressed and a lifter body rotatably supporting the roller and housed in a guide hole of a lifter guide so as to be reciprocable in the guide hole. The lifter body includes a cylindrical part and a rotation stopper. The cylindrical part has an outer periphery formed into a cylindrical shape such that the outer periphery is slidable on an inner periphery of the guide hole. The cylindrical part has one of two axial ends, the one end being formed with a skirt covering the roller. The rotation stopper is formed to protrude outward from the other axial end of the cylindrical part, the other axial end being located opposite a side where the skirt is located. The rotation stopper prevents the lifter body from being rotated about an axis thereof relative to the lifter guide.
