Claims

[Claims for Utility Model Registration] (1) A hollow cylindrical body made of carbon fiber-reinforced plastic that is rotatably driven, and consisting of a rubber tube that expands and contracts when air is injected and discharged, a lug portion, a lug stay, and a spring; A lug assembly whose lug portion protrudes and retracts from the surface of the hollow cylindrical body as it expands and contracts, a resin pipe inserted into the rubber tube and bored with an appropriate number of air holes, and an air seal joint connected to the rubber tube are arranged. In the winding core shaft, the lug part and the lug stay part of the lug assembly are integrally molded of engineering plastic, the core part or the outside is made of a metal material, and the expansion prevention ring and the air seal joint are made of engineering plastic. The spring attached to the lug assembly is a cantilever spring that projects obliquely upward from the base and both ends of the base, and the base is symmetrically fixed to the ends of the lug stay with resin. Shaft for winding core. (2) The winding core shaft according to claim 1, wherein the upper part of the lug of the lug assembly is made of ceramic, and the lower part of the lug and the lug stay are integrally molded with engineering plastic. (3) The volume according to claim 1, characterized in that the lug part of the lug assembly is reinforced with an H-shaped metal material, the upper part of the lug part is made of rubber material, and the lower part of the lug and the lug stay are integrally molded with engineering plastic. Core shaft.
