Abstract

A support structure for a vehicle molded by a casting mold, provided between a vehicle body and a vehicle component, and including a support portion which supports the vehicle component and a rib which is continuously formed on the support portion. The support structure for a vehicle includes a core portion recessed in a direction different from a mold split direction of the casting mold on a side surface portion of the rib.

First claim

What is claimed is:

1. A support structure for a vehicle molded by a casting mold, provided between a vehicle body and a vehicle component, and includes a support portion which supports the vehicle component and a rib continuously formed on the support portion,
comprising: a core portion which is recessed in a surface portion of the rib and which extends into a wall of a main body on an opposing side of a fitting hole.

2. The support structure for a vehicle according to claim 1 , wherein
the core portion includes an inclined wall surface expanding from a bottom surface of the core portion to an outer surface of the rib.

3. The support structure for a vehicle according to claim 2 , wherein
the inclined wall surface is smoothly continuous with the bottom surface and the outer surface of the rib.

4. The support structure for a vehicle according to claim 1 , wherein
a thickness from a bottom surface of the core portion to an inner surface of the rib is equal to a thickness from the inner surface to an outer surface of a tip end portion of the rib.

5. The support structure for a vehicle according to claim 2 , wherein
a thickness from a bottom surface of the core portion to an inner surface of the rib is equal to a thickness from the inner surface to an outer surface of a tip end portion of the rib.

6. The support structure for a vehicle according to claim 3 , wherein
a thickness from a bottom surface of the core portion to an inner surface of the rib is equal to a thickness from the inner surface to an outer surface of a tip end portion of the rib.

7. A method of manufacturing the support structure for a vehicle provided between the vehicle body and the vehicle component and includes the support portion which supports the vehicle component and the rib continuously formed on the support portion of claim 1 , comprising:
casting the support structure by a casting mold,
wherein the casting includes forming a core portion recessed in a direction different from a mold split direction on a side surface portion of the rib by punching with a punching mold that slides in a direction different from the mold split direction of the casting mold.

8. The support structure for a vehicle according to claim 1 , wherein the main body extends from the rib and includes the fitting hole.

9. The support structure for a vehicle according to claim 8 , wherein the core portion has an upper side that extends onto the main body.

10. The support structure for a vehicle according to claim 8 , further comprising a support portion connected to a periphery of the main body via the rib.
