Abstract
A member fastening structure has an installation member (for example, grommet) and a leg member (for example, pin). A projecting part, having at least one inclined surface, and a projecting wall, for contacting with the inclined surface of the projecting part and guiding in a direction of removing the leg member (for example, pin) from the installation member (for example, grommet) in a case when the leg member (for example, pin) is rotated in a state where elastic leg pieces are spread open, are provided between the installation member (for example, grommet) and the leg member (for example, pin).
Claims6
A member fastening structure, comprising:
- an installation member including a collar-form part having a through-hole in a thickness direction, and elastic leg pieces placed in series in a cylindrical form on another side than that of said collar-form part to form a cylindrical part connecting through to said through-hole of the collar-form part and having raised parts facing inner faces;
- and
- a leg member including a flange, and a wide-diameter part and a narrow-diameter part integrally projecting from said flange and continuing at least toward a leading-end side;
- a cam part placed rising in a circumferential direction of the wide-diameter part from the narrow-diameter part of said leg member;
- and the raised parts of the elastic leg pieces riding up on the cam part by insertion of said leg member into said installation member in which said elastic leg pieces are expanded;
- wherein a projecting part having at least one inclined surface, and a projecting wall for contacting with the inclined surface of said projecting part and guiding in a removing direction of said leg member from said installation member when said leg member is rotated in a state in which said elastic leg pieces are spread open, are provided between said installation member and said leg member.
A clip adapted to fasten a member, comprising:
- a grommet having a collar-form part, a leg part hanging down from said collar-form part, and a through-hole running through from the collar-form part to the leg part;
- and
- a pin having a shaft part capable of expanding said leg part in diameter by being inserted into said through-hole, and a flange part extending from said shaft part and having a larger diameter than said through-hole;
- wherein between said leg part and said shaft part, a recessed part and a raised part are provided either one on either part, fitting together elastically to prevent movement in an axial direction of said shaft part in said through-hole in a state in which said leg part is made capable of expanding in diameter;
- in a circumferential direction of said recessed part, a lock-releasing part is provided to elastically contact with said raised part released from said recessed part and for allowing movement in the axial direction of said shaft part in said through-hole when said flange is rotated in a state in which the recessed part and the raised part are fitted together;
- and
- said lock-releasing part is provided with an inclined surface urging in a direction releasing said shaft part from said through-hole using an elastic return force of said raised part elastically contacting with the lock-releasing part.
A clip adapted to fasten a member, comprising:
- a grommet having a collar-form part, a leg part hanging down from said collar-form part, and a through-hole running through from the collar-form part to the leg part;
- and
- a pin having a shaft part capable of expanding said leg part in diameter by being inserted into said through-hole, and a flange part extending from said shaft part and having a larger diameter than said through-hole;
- wherein a recessed part and a raised part fitting together elastically to prevent movement in an axial direction of said shaft part in said through-hole in a state in which said leg part is made capable of expanding in diameter, are provided, either one on either part, between said leg part and said shaft part;
- a lock-releasing part is provided in a circumferential direction of said recessed part for allowing movement in the axial direction of said shaft part in said through-hole when said flange is rotated in a state in which the recessed part and the raised part are fitted together;
- an elastic body having elasticity is provided on a perimeter edge of said flange;
- said collar-form part is provided with a wall part to elastically contact with said elastic body in a state in which said leg part is made capable of expanding in diameter;
- and
- when said flange is rotated in the state in which said leg part is made capable of expanding in diameter, by an elastic return force accumulated in said elastic body, said shaft part is urged in a direction to be released from said through-hole.
