Claims

[Scope of Claim for Utility Model Registration] (1) A male joint part and a female joint part which can be freely fitted to each other are provided at the ends of a pair of shafts that transmit rotational force to each other, and the male joint part In a shaft coupling device in which the male joint part and the female joint part are fitted together with both shafts abutting each other coaxially, the distal end surface of the male joint part has a diameter that decreases as it goes forward. A convex portion formed on a curved surface is concentrically arranged and protruded, and a concave portion into which the convex portion is rotatably fitted is concentrically arranged and recessed on the bottom surface of the female joint portion. A shaft coupling device characterized by: (2) In paragraph 1 of the claims for utility model registration,
A shaft coupling device in which the maximum outer diameter of the convex portion is set to be greater than the width of the male joint. (3) Scope of claims for utility model registration, paragraph 1 or 2
2. The shaft coupling device according to item 1, wherein the outer shape of the male coupling portion is formed in a curved surface shape whose diameter gradually becomes smaller as it goes in a direction away from the tip end surface.
