The clip has a lock portion to be locked and a nut to be screwed onto the bolt, and the clip is assembled to the plate so that the lock leg extends from the plate. The clip extends from the portion along the locking leg, and the clip is integrally assembled to the plate .

  The nut member has a simple structure of a metal plate with a nut and a plastic clip with a locking leg that holds the plate, and a pair of locking legs are inserted into the mounting holes of the mounted member. As a result, since it is fixed to the member to be attached, the attachment work to a flat member to be attached such as a body panel can be easily performed even when there is only a narrow space. The pair of locking legs are fixed to the attached member so as not to rotate the clip, and thereby the plate nut fixed to the clip is fixed to the attached member so as not to rotate. When fixing the mounting member, it is not necessary to hold the nut (and thus the nut member) by hand so as not to rotate. As a result, the bolting operation can be more easily and reliably performed.

  In the nut member, the clip is formed in an elongated box shape in which the side from which the locking leg extends is closed by the plate, and the clip is assembled to the plate so as to cover and cover the nut between the pair of locking legs. It is preferable. As a result, the nut member has an elongated rectangular parallelepiped compact shape as a whole, is easy to handle, and can be easily attached to the member to be attached. Further, the nut may be a press-fit nut fixed by press-fitting into a hole of the plate, or a burring process is performed at a predetermined position of a metal plate to form a cylinder rising from the plate, and the nut is formed inside the cylinder. An internal thread may be formed by tapping.
