Reference numeral 1 denotes a hood ledge panel which constitutes a side wall of an engine room (E / R), and a shelf 2 is formed on a front side portion thereof. A rectangular battery tray 3 is arranged on the upper surface of the shelf portion 2 by joining, and a reinforcement 4 is joined on the lower surface to reinforce. The battery 5 is placed on the battery tray 3, and the peripheral side is covered with a cover 6 made of a heat-resistant resin material. For the battery 5 and the cover 6, the upper end of a fixing rod stay 7 hooked to the front and rear edges of the battery tray 3 is inserted into a holding frame 8 arranged on the upper surface of the battery 5, and the rod stay 7 is inserted. A nut 9 is screwed and fastened to the threaded portion of the projecting end of 7 to be fixed on the battery tray 3. In the figure, 10 is a radiator core support panel, and 11 is an engine hood. This similar structure is disclosed, for example, in Japanese Utility Model Laid-Open No. 62-135354.

[0003]

[Problems to be solved by the device]

 Since the end portion of the rod stay 7 projects above the battery 5, it is necessary to secure a sufficient space a between the upper end portion of the rod stay 7 and the engine hood 11 to avoid interference, and particularly, the engine hood. 11 The slant nose type vehicle, which lowers the ground clearance at the front end, is severely restricted in its molding. The lower end hook of the rod stay 7 is attached to the front and rear edges of the battery tray 3 to hold the upper end and tighten the nut 9 onto the frame 8, but the position is fixed when the rod stay 7 is attached. As a result, the workability of assembly will deteriorate. Further, a sealing material 12 such as urethane is interposed between the lower edge portion of the cover 6 and the upper edge portion of the battery tray 3 so as to fill the gap between them so as not to impair the heat resistance effect. However, the matching between the lower edge of the cover 6 and the upper edge of the battery tray 3 may be poor, and the sealing material 12 may be displaced and the desired effect may not be obtained.

Therefore, according to the present invention, the upward protrusion of the fastening member for fixing the battery can be kept as small as possible, and the assembling workability can be remarkably improved, and the battery can be installed in the engine room. It is intended to provide a battery mounting structure for an automobile, which can surely be protected from a thermal effect inside.
