Abstract

A clamp including: a holding portion and a fixing portion, wherein the fixing portion includes: a base, a support shaft that extends from 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, a spring that is provided in a surrounding region of the support shaft between the base and the lock, and is formed so as to be extendable in a direction in which the support shaft extends, and a vibration suppressor provided between two opposing surfaces of the spring that are adjacent to each other in a direction in which the support shaft extends and face each other.

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,
a support shaft that extends from 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,
a spring that is provided in a surrounding region of the support shaft between the base and the lock, and is formed so as to be extendable in a direction in which the support shaft extends, and
a vibration suppressor provided between two opposing surfaces of the spring that are adjacent to each other in a direction in which the support shaft extends and face each other.

2. The clamp according to claim 1 , wherein:
the spring includes a plate spring that includes two plate members that are adjacent to each other in the direction in which the support shaft extends, and an elastic deformation portion connecting end portions of the two plate members, and
the vibration suppressor is provided between the two plate members.

3. The clamp according to claim 2 ,
wherein the spring is formed by the plate spring in a plurality of levels connected to each other in the direction in which the support shaft extends, and has a wave-shaped cross-section in which an S-shape continues in the direction in which the support shaft extends.

4. The clamp according to claim 2 , wherein:
one end of each plate member is provided with a notch that extends from the one end toward a plane central portion of the spring and into which the support shaft is insertable, and
the notch is formed so as to extend in a direction intersecting the direction in which the support shaft extends and pass through the plate member in a thickness direction.

5. The clamp according to claim 4 ,
wherein the elastic deformation portion is provided with a through-hole into which the support shaft is insertable such that the through-hole is in communication with the notch.

6. The clamp according to claim 1 ,
wherein the vibration suppressor is formed in a sheet shape.

7. The clamp according to claim 1 ,
wherein the base is provided with an accommodation portion in which a portion of the spring is accommodated.

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

9. The clamp-equipped wire harness according to claim 8 , 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.
