Description

  The present invention relates to a battery attachment structure for a vehicle in which a battery is attached to a front side frame at the front of a vehicle body.

  In many vehicles in which the battery is mounted in the engine room at the front of the vehicle body, the battery is attached to a front side frame that is a skeleton member. In this case, the battery is attached to a battery support base attached on the front side frame via a metal restraining tool. Moreover, the battery harness connected to the electrode part of the battery is routed around the battery and connected to a power use device such as an engine (see, for example, Patent Documents 1 and 2).

  In the vehicle described in Patent Document 1, a battery harness having one end connected to an electrode portion of a battery is drawn downward from a side portion of the battery and is related to a rectifying plate disposed to face the side portion of the battery. It is locked by a stopper.

  Further, in the vehicle described in Patent Document 2, the battery harness whose one end is connected to the electrode portion of the battery is pulled out to the front of the battery and routed along the panel member at the front of the vehicle.
