ABSTRACT:
A resin coated piston manufacturing apparatus for a shock absorber is provided with a means for pressing a piston raw material to a resin sheet until the resin sheet is locked to a resin sheet locking annular groove of the piston raw material in such a manner as to be capable of reciprocating on a center axis of a set mold. The apparatus having an aligning guide mateable with an inner diameter of the piston raw material set to a piston set hole of the set mold. The aligning guide presses the piston raw material to the resin sheet so as to lock the resin sheet to the resin sheet locking annular groove of the piston raw material, and can press the piston raw material to which the resin sheet is locked, to a heating and cooling cylinder apparatus.
