Claims

[Scope of Claim for Utility Model Registration] A base having an opening corresponding to a piston assembly to be inserted into a cylinder block of an engine, and a piston head erected at the opening of the base, the inner diameter of which corresponds to the piston head of the piston assembly. A piston guide tube is formed with a tapered inner circumferential surface corresponding to the outer diameter of the cylinder head and whose inner diameter decreases toward the opening, and the piston guide tube is attached to the base by matching with the mounting screw hole of the cylinder head of the cylinder block. A piston assembly insertion device comprising: a protruding reference knock pin; and a contact member disposed at a distance from the reference knock pin for bringing the base into close contact with the cylinder block together with the reference knock pin. .
