Abstract

A clip includes a clip body, and a pin inserted into the clip body. The clip body includes a main body head portion having a through-hole for inserting the pin, a leg portion extending from the head, and an elastic engaging piece elastically deformable, and projecting outward from the leg portion. The pin includes a pin head portion provided with a tool-engaging portion engaging a tool for a rotational operation, and a pin shaft portion having small and large diameter portions. The main body head portion includes an inclined surface inclined from one end side toward another end side in an axial direction of the through-hole. The pin includes a guide portion slidingly contacting with the inclined surface. When the pin rotates inside the clip main body, the pin advances and retracts between a first position allowing an inward elastic deformation and a second position controlling an inward elastic deformation.

First claim

1 . A clip, comprising:
a clip main body for mutually fixing first and second members; and a pin inserted into the clip main body rotatably and to advance and retrace, wherein the clip main body includes: a main body head portion having a through-hole into which the pin is inserted; a leg portion extending from the main body head portion, and adapted to be inserted into attachment holes of the first and second members; and an elastic engaging piece provided to be elastically deformable in a direction of intersecting in an insertion direction of the pin, and projecting outward from the leg portion adapted to lock the attachment hole of the second member, the pin includes: a pin head portion provided with a tool-engaging portion adapted to engage a tool carrying out a rotational operation thereof; and a pin shaft portion having a small diameter portion and a large diameter portion, the main body head portion includes an inclined surface, extending along an inner peripheral edge portion of the through-hole, and inclined from one end side toward another end side in an axial direction of the through-hole, and the pin includes a guide portion slidingly contacting with the inclined surface, wherein when the pin rotates inside the clip main body in a condition where the guide portion slidingly contacts with the inclined surface, the pin advances and retracts between a first position allowing an inward elastic deformation thereof by facing the small diameter portion with the elastic engaging piece, and a second position controlling an inward elastic deformation thereof by facing the large diameter portion with the elastic engaging piece.

2 . A clip according to claim 1 , wherein the pin moves from an advanced position which is the first position to a retracted position which is the second position, so that the first and second members come to a mutually fixed state.

3 . A clip according to claim 1 , wherein the main body head portion includes a rotation-control concave portion disposed on one end side of the inclined surface, into which the guide portion is inserted when the pin is located in the second position.

4 . A clip according to claim 1 , further comprising a lid body attached to an insertion side of the pin in the clip main body,
wherein the lid body includes an urging piece urging the pin in an insertion direction of the guide portion relative to the rotation-control concave portion when the pin is located in the second position.

5 . A clip according to claim 1 , wherein the main body head portion includes a rotation-control convex portion positioned on another end side of the inclined surface, and abutting against the pin which is located in the first position to control a rotation of the pin into a second position side.

6 . A clip according to claim 1 , wherein the main body head portion includes a rotation control wall projecting inward from an inner peripheral face of the through-hole at least at one end portion of the inclined surface, and controlling a movement of the guide portion.

7 . A clip according to claim 6 , wherein the rotation control wall abuts against the guide portion respectively in the first position and the second position of the pin, and controls a further movement of the pin which is located in the second position while controlling a further movement of the pin which is located in the first position.

8 . A clip according to claim 7 , wherein the main body head portion includes an escape-control projecting portion positioned on another end side of the inclined surface, and projecting inward from the inner peripheral face of the through-hole in such a way as to abut against the pin which is located in the first position from an anti-insertion side thereof.
