A wire harness includes a high-voltage wire and a pipe member for receiving the high-voltage wire. The pipe member is provided, at a plurality of points thereon, with crushed portions formed by crushing a pipe outer surface inward. The crushed portions are formed as portions to which clamps are to be attached. The crushed portions are formed and positioned in correspondence with positions of L-shaped brackets. The crushed portions are formed as portions for generating protrusions on a pipe inner surface, and the protrusions serve as a contact supporting point for the high-voltage wire.

Provided are a braided shield member, a manufacturing method of a braided shield member and a wire harness which make it possible to demonstrate shielding performance sufficiently. The braided shield member constituting the wire harness includes a tubular body part and a tubular terminal part. The braided shield member is formed so that the terminal part is formed in a two-folded structure of an outside terminal part and an inside terminal part. Further, the braided shield member is formed so that metal wires are in a loose state inside stitches of the outside terminal part.

A flow rate control device comprises a regulator that adjusts the pressure of a fluid to be supplied, a plurality of narrowed pathways arranged in parallel on the downstream side of the regulator, and an open/close section that switches a predetermined narrowed pathway amongst the plurality of narrowed pathways between an open position and a closed position. One of the pathways can be an open narrowed pathway arranged on the downstream side of the regulator and another can be an opened/closed narrowed pathway arranged downstream of the regulator in parallel with the open narrowed pathway. In this case, the open/close section that switches the opened/closed narrowed pathway between as open position and a closed position.
