Description

Wire harness Technical Field The present disclosure relates to wire harnesses. Background Conventionally, a wire harness is known which includes a bellows that covers an outer periphery of a wire member, and a path restricting member that covers a part of the bellows in a circumferential direction and restricts a path through which the wire member is routed (for example, see 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 fitting member provided in the slit. The fitting member is configured to be capable of being engaged 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 can be restricted by fixing these bellows, path maintaining member, and fitting member by tape winding or the like. 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 wire harness described in patent document 1, the fitting member is provided in the slit of the corrugated tube. Therefore, there is a possibility that a gap is generated between the fitting member and the slit. Such a gap is not preferable in improving the water-stopping property of the wire harness. The purpose of the present disclosure is to provide a wire harness that can suppress a decrease in water-stopping properties. 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 regulating 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 regulate a path along which the wire member is routed, the path regulating member having an insertion port that is open in a direction orthogonal to the longitudinal direction of the path regulating member and extends over the entire longitudinal direction, the insertion port being configured to be insertable into the outer member, a1 st end portion and a2 nd end portion that are located opposite to each other in the circumferential direction of the path regulating member to form the insertion port, and a protruding portion that protrudes from an inner surface of at least one of the 1 st end portion and the 2 nd end portion toward the outer member to be in contact with an outer surface of the outer member.
