The purpose is to provide a support structure.

  In order to solve the above-described problems, a support structure for an electronic device according to the present invention includes a shelf board support that is fixed to a vehicle body and defines a storage space, and is arranged at a predetermined position in the storage space and intersects with the vertical direction. A shelf board, a fixing member that fixes the shelf board in the accommodation space to the shelf board support body at a predetermined position, and an elastic member that is interposed between the shelf board support body and the shelf board. The shelf board support body has a vertical plate portion that stands up along a predetermined direction and partitions one side of the storage space, a locking hole that penetrates the vertical plate portion, and an opening that opens the other side of the storage space. Have. The shelf board protrudes downward from the shelf board body that holds the electronic device, the locking projection that protrudes to the outside through the locking hole at a predetermined position, and the tip of the locking projection that protrudes to the outside. A protrusion is integrally formed. The locking hole has a height that allows insertion of the locking protrusion and the protrusion from the housing space to the outside. The elastic member is fixed to one of the locking hole or the locking projection, and is interposed between the locking hole and the locking projection to elastically support the locking projection.

  According to this, when arranging a shelf board in the predetermined position of the accommodation space of a shelf board support body, a shelf board is inserted into the accommodation space from the opening of the shelf board support body, and the locking protrusion and protrusion of the shelf board The portion is inserted into the locking hole of the vertical plate portion of the shelf board support, and the shelf board is fixed to the shelf board support by the fixing member. In such shelf board insertion work, the shelf board can be appropriately tilted to a desired angle with respect to the shelf board support so that the shelf board can be moved, so when other parts are attached in the vicinity of the opening.
