  However, in the above-mentioned corner member fitting, the fitting portion bent in a U shape cannot be deformed if the fitting is first attached to the pillar (support material), and therefore, it is deep in the fitting groove. It has a structure that makes it impossible to insert. For this reason, it is necessary to attach the fixture to the protruding corner material (attachment) before attaching the fixture to the pillar (supporting material). There was a problem that (attachment) could not be attached to the fixture.

  In addition, since the range in which the fitting groove engaging protrusion can be displaced by the elastic deformation is reduced as a whole, the fitting groove engaging protrusion is not effectively engaged with the fitting groove in some cases, and attachment is uncertain. There was also a problem of fear.

  The present invention has been made in view of such a conventional situation, and the object of the present invention is to attach the attachment to the support first and then attach the attachment to the attachment. An object of the present invention is to provide an attachment that can be attached to a support member after the attachment is attached.

  Another object of the present invention is to increase the elastic displacement range of the engagement piece engaged with the inner surface of the recessed portion of the attached object, so that the engagement piece is always effectively brought into elastic contact with the inner surface of the recess. The object is to provide a fixture that can be securely attached to a support material.

  Still other objects of the present invention will become apparent from the following description.
