Abstract

A clamp including: a holding portion configured to hold a wire harness; and a fixing portion that is provided in a portion of an outer circumferential surface of the holding portion and is to be fixed to a fixed portion; wherein the fixing portion includes: a base that includes a first surface that faces a holding portion side and a second surface located opposite to the first surface, a support shaft that extends from the second surface of the base in a direction away from the holding portion, a lock that is provided at a leading end of the support shaft and is formed to be able to be locked to the fixed portion, and a vibration suppressor that is made of a material whose elastic modulus is lower than that of the base and protrudes from the second surface of the base toward a lock side.

First claim

The invention claimed is:

1. A clamp comprising:
a holding portion configured to hold a wire harness; and
a fixing portion that is provided in a portion of an outer circumferential surface of the holding portion and is to be fixed to a fixed portion;
wherein the fixing portion includes:
a base that includes a first surface that faces a holding portion side and a second surface located opposite to the first surface,
a support shaft that extends from the second surface of the base in a direction away from the holding portion,
a lock that is provided at a leading end of the support shaft and is formed to be able to be locked to the fixed portion, and
a vibration suppressor that is made of a material whose elastic modulus is lower than that of the base and protrudes from the second surface of the base toward a lock side.

2. The clamp according to claim 1 , further comprising
a tubular spring that encloses an entire outer circumference of the support shaft,
wherein the spring is made of a material whose elastic modulus is lower than that of the support shaft.

3. The clamp according to claim 2 ,
wherein the spring is formed to enclose the outer circumference of the support shaft over an entire length of the support shaft in a direction in which the support shaft extends.

4. The clamp according to claim 2 , wherein:
the support shaft is formed in a round columnar shape,
the spring is formed in a cylindrical shape, and
the vibration suppressor is formed in an annular shape surrounding an outer circumference of the spring in a plan view.

5. The clamp according to claim 1 , wherein:
the second surface of the base is provided with a groove, and
a portion of the vibration suppressor is fitted to the groove.

6. The clamp according to claim 1 , wherein:
a planar shape of the base is larger than a planar shape of the lock, and
the vibration suppressor is formed in an annular shape having a through-hole whose planar shape is larger than that of the lock.

7. The clamp according to claim 1 , wherein:
the vibration suppressor includes a plurality of divided bodies, and
the plurality of divided bodies are spaced apart from each other on the second surface of the base.

8. The clamp according to claim 1 ,
wherein a portion of the vibration suppressor that protrudes from the second surface of the base toward the lock side is formed in a semicircular shape in a cross-sectional view.

9. A clamp-equipped wire harness comprising:
the clamp according to claim 1 ; and
the wire harness held by the holding portion.

10. The clamp-equipped wire harness according to claim 9 ,
wherein the wire harness includes:
a wire,
an outer cover in which the wire is accommodated and whose outer circumference is enclosed by the holding portion,
a spacer provided in an internal space of the outer cover in a portion enclosed by the holding portion, and
the spacer is formed so as to fill a space between an outer circumferential surface of the wire and an inner circumferential surface of the outer cover.
