Abstract: A wire harness includes plural types of connectors connected to connection destinations different from each other and a plurality of wirings connecting the plural types of connectors to each other. The plural types of connectors include an apparatus connector connected to a connector of an apparatus and plural types of harness connectors to which connectors of counterpart wire harnesses different from each other are connected, respectively. The plurality of wirings include a through circuit wiring connecting a first harness connector and a second harness connector in the plural types of harness connectors and a plurality of apparatus wirings connecting the apparatus connector to the first harness connector and the second harness connector.

Abstract: A wire harness includes: an apparatus connector connected to a connector of an apparatus; a first harness connector connected to a connector of a first counterpart wire harness; a second harness connector connected to a connector of a second counterpart wire harness; a first apparatus wiring connecting the apparatus connector and the first harness connector; a second apparatus wiring connecting the apparatus connector and the second harness connector; and a flat base member holding the first apparatus wiring and the second apparatus wiring.

Abstract: A wiring member includes: at least one wiring body including a sheet and a wire-like transmission member fixed to the sheet; and a regulation member including a housing part and a retaining piece and attached to the wiring body. The housing part includes a bottom part and two sidewall parts protruding from the bottom part. The wiring body is housed in the housing part while both end portions along a width direction are bended with respect to an intermediate portion and extend toward a tip end portion of each of the two sidewall parts. The retaining piece protrudes above the housing part from the tip end portion of each of the two sidewall parts to press the end portions of the wiring body.
