Fastener

A fastener for mounting a member to be mounted on a mount member, comprising:

• a band for fastening a member to be mounted;
• a band fastening portion for locking the band which is tightened to fasten the member to be mounted;
• and
• a mounting portion for mounting the band fastening portion on a mount member,
• wherein the band fastening portion has:
• a passage hole having an inlet opening and an outlet opening for the band;
• a locking claw which locks on the band which is passed through the passage hole;
• a supporting wall portion which surrounds the member to be mounted together with the band which is passed through the passage hole;
• and
• a pair of side wall portions which are positioned individually on both sides of the passage hole while connecting to both sides of the supporting wall portion,
• wherein the supporting wall portion extends in a direction from the inlet opening towards the outlet opening and has end faces which lie individually on a side thereof which faces the inlet opening and a side thereof which faces the outlet opening,
• wherein the band has a proximal end portion which extends from the end face of the supporting wall portion which lies on the side thereof which faces the outlet opening,
• wherein the pair of side wall portions are disposed so as to define a gap in a widthwise direction between the proximal end portion of the band and themselves,
• wherein end faces of the pair of side wall portions which lie on sides thereof which face the outlet opening project further in a passing direction of the band through the passage hole than the end face of the supporting wall portion which lies on the side thereof which faces the outlet opening, and
• wherein the proximal end portion of the band is hidden behind one of the pair of side wall portions when seen in a direction perpendicular to the passing direction of the band.
