Wire harness fixing structure

A wire harness fixing structure, comprising:

• a silencer disposed between a floor mat and a body in a vehicle;
• a wire harness disposed along a main surface of the silencer;
• a fixing member fixing the wire harness to the silencer, wherein
• a bottomed hole having a bottom is formed in the silencer to be concaved from the main surface in a thickness direction, and
• the fixing member is locked to the bottomed hole, thereby fixing the wire harness to the silencer;
• and
• the silencer includes a silencer body part and a locking member which is formed of a material having higher rigidity than the silencer body part,
• the locking member being integral with the silencer body part, and the locking member having the bottomed hole, wherein
• the locking member includes a shaft extending from one end portion exposed to a side of the main surface of the silencer body part toward an inner side of the silencer body part, the shaft having the bottomed hole formed therein and a retaining part linking to another end portion of the shaft to prevent the shaft from getting out of the silencer body part, and
• the fixing member has an insertion part formed into a rod-like shape to be inserted into and locked to the bottomed hole formed in the shaft and an insertion regulating part formed on a base end of the insertion part to regulate a further insertion of the insertion part into the bottomed hole.
