Claims

[Claims for Utility Model Registration] A shaft portion that is rotatably inserted into a non-circular insertion hole formed in a long and thin plate-like portion of a base material, and integrally formed on one end side of the shaft portion, a flange that cannot be inserted into the insertion hole regardless of the rotational position of the shaft; and a flange that is integrally formed on the other end of the shaft and is inserted into the insertion hole in a first state at a predetermined rotational position; a retaining body that is capable of being inserted into the insertion hole in a second state rotated approximately 90 degrees from the first state; In the rotary locking structure in which the plate-shaped portion is held between the flange portion and the retaining body by setting the second state after insertion, the inner end surface of the insertion hole has a A pair of opposing flat portions extending in the longitudinal direction and substantially parallel to each other is formed, and the shaft portion has a pair of leg portions separated by a slit extending over the entire radial length of the shaft portion. and, at a rotational position midway between the first state and the second state, the pair of legs is pinched and pressed by the pair of flat parts so that the pair of legs approaches each other. Rotary locking structure.
