Claims

[Claims for Utility Model Registration] A bottomed cylindrical joint body that is connected to a drive shaft and has a plurality of axial grooves formed on its outer peripheral surface, and a driven shaft that is inserted into the joint body through its opening. a large-diameter shaft joint comprising: a thick wall portion facing the groove of the joint body; and a thin wall portion facing the general portion of the joint body so as to fit with the joint body; a ring portion; a small diameter ring portion fixed to the driven shaft; and a bellows portion interposed between the large diameter ring portion and the small diameter ring portion, the large diameter ring relative to the joint main body. The part is fixed to a metal band-like member whose palms are joined at both ends, a lever fixed to a side surface of the palm-joint part, and a part of the band-like member for fixing the lever in a tightened state. The boot for a mechanical shaft joint is made up of a metal fastening band configured to include a stopper part, and the palm part is bent by the lever action of the lever to tighten the object to be fastened, the boot for a mechanical shaft joint. The radius of curvature connecting the thick wall portion and the thin wall portion on the inner peripheral surface of the diameter ring portion is made larger than the radius of curvature connecting the general portion and the groove on the outer peripheral surface of the joint body, and the large diameter with respect to the joint body A machine characterized in that the compression ratio of the ring portion is greater in the thick wall portion than in the thin wall portion, and a circumferential relief groove is formed in the inner peripheral surface of the thick wall portion. Boots for shaft couplings.
