SHEATH ASSEMBLY AND WIRE HARNESS

A sheath assembly applied to a wire harness includes: a protector that includes a base member to which a wiring material is inserted, and a cover member; and a movable sheathing material which is attached to the base member in a movable manner and to which the end part of the wiring material housed in a housing space part can be inserted. The cover member includes a positioning part that is formed to protrude toward the housing space part side in a state where the cover member is assembled to the base member and that maintains a connection state between the base member and the movable sheathing material by abutting against a connection part of the movable sheathing material to the base member.
