  However, in such a conventional protector, for example, when the protector is packed or removed from the package, a load is applied in the direction of separating the protector body and the cover from each other on the other end side in the length direction. And stress will concentrate on the center part of the hinge provided in the one edge part side of the length direction.

  In particular, the thickness of the central portion of the hinge (hereinafter referred to as the hinge thickness) is set to be thinner than the other portions so that the cover can be easily folded. Therefore, in the conventional protector, when stress concentrates on the central part where the hinge thickness is thin, the hinge may be damaged.

  In this respect, by increasing the thickness of the hinge, it is possible to prevent damage due to stress concentration, but this impairs the original function of the hinge, which is easy to bend.

  The present invention has been made in view of the circumstances as described above, and an object of the present invention is to provide a protector capable of preventing the hinge from being damaged without impairing the original function of the hinge, which is easy to bend.

  In order to achieve the above object, a protector body according to the present invention includes a protector body that houses a wire harness, a cover that closes an open end of the protector body, and the protector body that covers the cover to the protector body. A protector that is integrally formed with a hinge that is connected so as to be openable and closable at either one end in the length direction, and that has a thin wall portion between the end on the cover side and the end on the protector body side The hinge includes a pair of projecting portions provided on the cover side and the protector main body side with the thin portion interposed therebetween, and projecting to the other end portion side in the length direction. In this open state, the fitting member that fits into the pair of protrusions is provided as a separate body.

  With this configuration, the protector according to the present invention is provided with a pair of protrusions protruding on the other end side in the length direction of the protector body and the cover on the hinge, and fitted to the pair of protrusions when the cover is open. The fitting member which performs is provided as a separate body. For this reason, the intensity | strength of the thin part of a hinge can be improved by making a fitting member fit a pair of protrusion part in the open state of a cover.

  Therefore, for example, when the protector main body and the cover are separated from each other when packing the protector or when removing it from the package, stress is not concentrated on the thin wall portion of the hinge, and the end of the hinge on the cover side It can prevent that a part and the edge part by the side of a protector main body displace in the direction which mutually spaces apart. Thereby, the breakage of the hinge is prevented.

  Moreover, since the fitting member for reinforcing the hinge is a separate member, when the cover is bent with respect to the protector main body, the original function of the hinge that it is easy to bend by simply removing the fitting member can be exhibited.

  Thus, the protector according to the present invention can prevent the hinge from being damaged without impairing the original function of the hinge, which is easy to bend.

  Moreover, the protector of the said structure WHEREIN: It is preferable that the said fitting member has a retaining part which prevents the said fitting member from falling out with respect to the said protrusion part.

  With this configuration, the protector according to the present invention has the retaining member for the protruding portion with respect to the protruding portion. Therefore, after the fitting member is fitted to the protruding portion, the fitting member can be easily detached from the protruding portion. Can be prevented.
