Claims

[Claims for Utility Model Registration] A bushing holding space is provided at at least one connecting end of a rod member made of a synthetic resin material, and a bushing holding space is provided integrally with the shaft member and its outer peripheral surface. A connecting rod with a rubber bush is fitted with a rubber bush formed by a fixed cylindrical elastic body, and the bush holding cavity is connected to the bush main housing hole, the bush support hole, and both holes. and a mounting portion with a locking head that protrudes radially outward on the outer peripheral surface of the cylindrical elastic body of the rubber bushing and is locked in the bushing support hole of the bushing holding cavity. By locking the locking head with the bushing support hole, the rubber bushing is prevented from coming off in the direction perpendicular to the axis, and an uneven fit is provided between the mounting portion and the bushing support hole or the connecting portion. A connecting rod with a rubber bush, characterized in that a coupling mechanism is formed to prevent the rubber bush from coming off in the axial direction.
