Abstract

The wire harness (10) is provided with a wire member, an exterior member (30) that covers the outer periphery of the wire member, a path limiting member (40) that covers a part of the outer member (30) in the circumferential direction and limits the path along which the wire member is routed, and a fixing member (50) that holds the path limiting member (40) and is fixed to the vehicle body. The path limiting member (40) has an insertion opening (44) extending in the longitudinal direction of the path limiting member (40) and configured to be insertable into an opening of the exterior member (30), and a 1 st end (41) and a2 nd end (42) located opposite to each other in the circumferential direction of the path limiting member (40) to form the insertion opening (44). The fixing member (50) has an engagement portion (63) protruding toward the insertion port (44), and the engagement portion (63) is contactable with the 1 st end (41) and the 2 nd end (42) in the circumferential direction of the path limiting member (40).

Description

Wire harness Technical Field The present disclosure relates to wire harnesses. Background Conventionally, a wire harness is known which includes a corrugated tube covering an outer periphery of an electric wire member, and a path restricting member covering a part of the corrugated tube in a circumferential direction and restricting a path along which the electric wire member is laid (for example, refer to patent document 1). The corrugated tube in the wire harness described in patent document 1 has a slit formed along the longitudinal direction. The path limiting member includes a path maintaining member provided along an outer periphery of the bellows and a mounting member provided in the slit. The mounting member is configured to be capable of being locked with an inner peripheral portion of the slit and an outer peripheral portion of the path maintaining member, respectively. The path of the wire member is restricted by fixing these bellows, path maintaining member, and mounting member by tape winding or the like. Further, a structure is considered in which the integrated bellows and path restricting member are, for example, intensively wound and held by a belt clip, and are fixed to the vehicle body by the belt clip, whereby the wire harness is fixed to the vehicle body. Prior art literature Patent literature Patent document 1 Japanese patent application laid-open No. 2013-55760 Disclosure of Invention Problems to be solved by the invention However, in the structure in which the path restricting member is held by the fixing member such as the belt clip as described above, there is a possibility that the path restricting member rotates in the circumferential direction with respect to the fixing member. The path limiting member is rotated relative to the vehicle body, for example, so that a portion not covered by the bellows path limiting member faces the ground and is exposed to the outside, and further, the durability of the wire harness can be reduced. An object of the present disclosure is to provide a wire harness capable of suppressing rotation of a path restricting member with respect to a fixing member fixed to a vehicle body. Means for solving the problems A wire harness includes a wire member, a tubular outer member covering an outer periphery of the wire member, a path restricting member covering a part of a periphery of the outer member in a circumferential direction of the outer member and extending in a longitudinal direction of the outer member to restrict a path along which the wire member is routed, and a fixing member holding the path restricting member and fixed to a vehicle body, the path restricting member having an insertion opening configured to be insertable into the outer member along the longitudinal direction of the path restricting member and extending over an entire length of the path restricting member, and a1 st end portion and a 2 nd end portion located opposite to each other in the circumferential direction of the path restricting member to form the insertion opening, the fixing member having an engaging portion protruding toward the insertion opening, the engaging portion being contactable with at least one of the 1 st end portion and the 2 nd end portion in the circumferential direction of the path restricting member. Effects of the invention According to the wire harness of the present disclosure, the path limiting member can be restrained from rotating relative to the fixing member fixed to the vehicle body.
