Description

Wire harness Technical Field The present disclosure relates to wire harnesses. Background Conventionally, a wire harness is known that includes a corrugated tube that covers an outer periphery of an electric wire member, and a path restricting member that covers a part of the corrugated tube in a circumferential direction and restricts a path along which the electric 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 is restricted by fixing the bellows, the path maintaining member, and the fitting 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 on a belt clip, and are fixed to a 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 wire harness described above, only a single path-maintaining member is provided along the outer periphery of the corrugated tube, and therefore there is a possibility that bending rigidity becomes low. The low bending rigidity of the path limiting member causes the wire member to be detached from the path. In the wire harness described above, since only a single path-maintaining member is provided along the outer periphery of the bellows, for example, when the wire harness is disposed at a position close to a heat source of a vehicle, there is a possibility that the temperature of the wire member may easily rise. As described above, the wire harness has a problem that the protection function of the wire member is low. The present disclosure is directed to a wire harness capable of improving a protection function of an electric wire member. Means for solving the problems A wire harness includes a wire member, a tubular outer member covering an outer periphery of the wire member, a1 st path limiting member mounted on an outer periphery side of the outer member, and a2 nd path limiting member mounted on an outer periphery side of the 1 st path limiting member, the 1 st path limiting member including a1 st main body portion covering a part of the outer periphery of the outer member, and a1 st insertion port formed by circumferential both end portions in the 1 st main body portion, extending along a longitudinal direction of the 1 st path limiting member and throughout the entire longitudinal direction, and configured to be insertable into the outer member, the 2 nd path limiting member including a2 nd main body portion covering a part of the outer periphery of the 1 st path limiting member, and a2 nd insertion port formed by circumferential both end portions in the 2 nd main body portion, extending along the longitudinal direction of the 2 nd path limiting member and throughout the entire longitudinal direction, and configured to be insertable into the 1 st path limiting member. Effects of the invention According to the wire harness of the present disclosure, the protection function of the electric wire member can be improved.
