Abstract

A suspension arm has an elongated shape. The suspension arm is shaped such that a line defining an outer shape of the suspension arm does not coincide with a line of force transmission, but a line extending through a shearing center point of each of a plurality of cross sections of the suspension arm coincides with the line of force transmission.

Claims

1. A suspension arm having an elongated shape,

wherein the suspension arm is shaped such that a line defining an outer shape of the suspension arm does not coincide with a line of force transmission, but a line extending through a shearing center point of each of a plurality of cross sections of the suspension arm coincides with the line of force transmission.

2. A suspension arm, comprising:

a pair of flanges each extending in a longitudinal direction of the suspension arm; and

a connector connecting the pair of flanges to each other,

wherein the suspension arm is bent with respect to the longitudinal direction,

wherein the connector is offset, with respect to a center point of the pair of flanges in a widthwise direction, to one of opposite sides of the center point, which one is nearer to a point of force action than another of the opposite sides.

3. The suspension arm according to claim 2,

wherein the connector is provided in a state in which a line extending through a shearing center point of each of a plurality of cross sections of the suspension arm coincides with a line extending through a point of force action.
