Abstract

The invention provides a support structure for a vehicle and a method of manufacturing the same. Weight reduction is realized. A support structure (10) for a vehicle is molded by a casting mold (22),provided between a vehicle body and a vehicle component, and including a support portion (12) which supports the vehicle component and a rib (14) which is continuously formed on the support portion (12). The support structure for a vehicle includes a core portion (16) recessed in a direction different from a mold split direction of the casting mold (22) on a side surface portion of the rib (14).

Description

technical field [0001] The present invention relates to a support structure for a vehicle capable of achieving weight reduction and a method for manufacturing the same. Background technique [0002] A steering knuckle (support structure for a vehicle) is a member that transmits a transmission force from a steering device to a wheel. As shown in Patent Document 1 (Japanese Patent Application Laid-Open No. 2013-144488 ) and the like, the steering knuckle has a main body and a support portion. Complicated irregular shape, in which the main body has a cylindrical fitting hole for fitting and fixing the axle (bearing), and the support part is connected to the periphery of the main body via ribs to connect and support the upper suspension, the lower suspension, and the steering knuckle Vehicle parts on the body side such as arms. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2013-144488 [0004] As described above, when a knuckle connects a plurality of support porti...
