Fastener structure for vehicle

A fastener structure for a vehicle in which a height adjustment spacer is interposed between a first vehicle body frame and a second vehicle body frame, and the first vehicle body frame and the second vehicle body frame are fixed by bolt fastening using a bolt and a nut, the fastener structure comprising:

• the nut having a first insertion hole through which the bolt is screwed, and being fixed to an inner side surface of the first vehicle body frame by welding;
• the height adjustment spacer having a second insertion hole through which the bolt is inserted, and being disposed in contact with an outer side surface of the first vehicle body frame;
• and
• the bolt being inserted through an attachment hole of the second vehicle body frame, the second insertion hole, an attachment hole of the first vehicle body frame, and the first insertion hole, wherein
• on a contact surface between the height adjustment spacer and the first vehicle body frame, a protrusion is provided to surround an entirety of the second insertion hole, and a recess is provided to surround an entirety of the second insertion hole in the vicinity of the protrusion, and wherein
• the attachment hole of the second vehicle body frame is defined by an inner cylinder of a bush fixed to the second vehicle body frame.
