Abstract: One aspect of the present disclosure provides a wire harness that can improve assembly workability. A wire harness (10) according to one aspect of the present disclosure comprises an electric wire (20) and an exterior member (40) formed of a tape member (50). The tape member (50) is wound on the outer circumference of the electric wire (20) in a spiral shape so that the tape member (50) does not partially overlap in the thickness direction. The tape member (50) comprises: a base material (51) having a first surface (51A) and a second surface (51B); an adhesive section (52) provided on one end section among both the widthwise end sections of the first surface (51A) of the base material (51); and a noon-adhesive section (53) provided on the other end section among both the widthwise end sections of the first surface (51A) of the base material (51) The tape member (50) has the adhesive section (52) disposed at the starting end in the advancement direction (P1) when being mounted in a spiral shape.

Abstract: A novel loosening prevention threaded fastener in which a clearance side protrusion portion protruding radially outwardly toward a clearance flank surface of a female screw thread is formed on a clearance flank surface of a male screw thread, and the clearance side protrusion portion is constructed such that a tip end portion thereof interferes with the clearance flank surface of the female screw thread, in a state where a pressure flank surface of the male screw thread is in contact with a clearance flank surface of the female screw thread. At the time of screw fastening, the crest end portion of the clearance side protrusion portion is pushed to the pressure flank surface of the female screw thread so that it is deformed in a deflective manner to apply a predetermined contact pressure to a contact surface due to its elastic restoring force, thus providing resistance against a loosening direction.
