タ。[Claims for Utility Model Registration] 1. A cylinder having a cylindrical part and a disc part formed inside the cylindrical part, the outer peripheral surface of the cylindrical part being slidably supported in a support hole formed in the cylinder head. , a valve lifter in which a valve stem of an intake/exhaust valve abuts a contact plate formed on the disk portion, and a shim that engages with a cam is disposed on a pressing surface located on the opposite side of the contact surface of the disk portion; A valve lifter, characterized in that it is formed from a hot-extruded rapidly cooled powder aluminum material and is provided with a wear-resistant surface layer on at least the outer peripheral surface of the cylindrical portion and the contact surface of the disc portion. 2. The valve lifter according to claim 1, which is a registered utility model, characterized in that a surface layer having wear resistance is provided on the pressing surface of the disk portion. 3. The valve lifter according to claim 1 or 2, wherein the surface layer includes a mixture of iron and phosphorus and is formed by electroplating. 4. The valve lifter according to claim 1, wherein the surface layer provided on the outer peripheral surface of the cylindrical portion is made of tetrafluoroethylene resin.
