Abstract

Provided is support structure of a pipe nut improving assemblability. The structure comprises a pipe nut 1 where one end side 1a is supported by matching to a hole part of a vehicle body frame 10, a bolt which is fastened to the pipe nut 1 through the hole part and supports a supported body to the vehicle body frame 10, and a reinforcing member 2 which is fixed to the vehicle body frame 10 and contacted to the other end surface 1b of the other end part of the pipe nut 1, and constituted so as to be mounted by welding the other end surface 1b of the pipe nut 1 and the reinforcing member 2.

Description

technical field [0001] The invention relates to a support structure of a pipe nut. Background technique [0002] A tubular nut (hereinafter simply referred to as a tubular nut) has a shaft portion that is elongated compared to a normal nut, and has an internal thread that engages with an external thread of a bolt on the inside. The tube nut is used, for example, to fasten the suspension member at the front end of the vehicle body to the frame extending in the front-rear direction of the vehicle body on both sides of the vehicle body with bolts. Although one end face of the tube nut is fixedly mounted on the vehicle frame, vibrations are generated at the other end of the tube nut because the shaft portion of the tube nut is relatively long. In order to suppress this vibration, the tube nut is fixed (locked) to the vehicle frame by using a reinforcing member. An example of a support structure of a conventional tube nut is shown in FIGS. 6 and 7 . [0003] In FIGS. 6 and 7 ,...
