Antenna

1. An antenna, comprising:

an electrical cable;

an antenna body including an element part and a ground part integrally formed from a metal plate, the element part having an electric wire connecting part electrically connected with the electrical cable; and

a resin antenna holder having an antenna holding part connected to the antenna body and a cable holding part holding the electrical cable in a direction different from a direction in which the electrical cable extends from the electric wire connecting part, the antenna holding part having a plurality of staking bosses and a constriction smaller in width than other parts of the antenna holding part, the cable holding part having a holding floor, a holding wall standing from a first end in the width direction of the holding floor, and a plurality of first holding claws, the antenna holder preventing pull forces and vibration occurring on the electrical cable from being transmitted to the electric wire connecting part.

2. The antenna of claim 1 , wherein the antenna holder is an electrically insulating material.

3. The antenna of claim 1 , wherein the plurality of first holding claws each stand with an interval along an opposite second end in a width direction of the holding floor and are opposed to the holding wall.

4. The antenna of claim 3 , wherein a first end of the holding wall is cut out to form a path and an opposite second end of the holding wall is bent in an L-shape.

5. The antenna of claim 4 , wherein the L-shape of the holding wall is continuous with a holding slot extending through the holding floor.

6. The antenna of claim 5 , wherein the holding slot has a second holding claw projecting toward an inside of the holding slot.

7. The antenna of claim 6 , wherein the electrical cable extends through the constriction and the path, and is perpendicularly bent to extend between the holding wall and the holding claws.

8. The antenna of claim 7 , wherein the electrical cable extends to the back side of the holding wall through the holding slot.

9. The antenna of claim 1 , wherein the staking bosses are fixed to staking holes formed in the element part through heat staking.

10. The antenna according to claim 1 , wherein the electric wire connecting part of the element part is disposed at a position that does not overlap with the antenna holding part and the cable holding part.

11. The antenna of claim 1 , wherein the element part has a u-shaped cross section forming a receiving groove.

12. The antenna of claim 11 , wherein the antenna holding part is fitted into the receiving groove.

13. The antenna of claim 12 , wherein the cable holding part is disposed along the ground part.

14. The antenna of claim 13 , wherein a tab of the cable holding part partially overlaps and holds the ground part.
