Abstract

The present invention provides a supporting structure for a vehicle and a manufacturing method thereof, which can achieve weight reduction. The vehicle support structure (10) is formed by a casting mold (22) and is arranged between the vehicle body and the vehicle parts, and has a support part (12) supporting the vehicle part and a rib formed continuously with the support part 12 ( 14) A casting punch (16) recessed in a direction different from the parting direction of the casting mold (22) is provided on the side surface of the rib (14).

Description

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