The interior illumination lamp 1 can be held by engaging the clip with one edge of the interior illumination lamp and sandwiching the other end between the functional part main body and the design part. That is, since only one of the clips needs to be provided, the indoor lighting can be reduced in size.

  Here, an elastic member projecting from the functional unit main body toward the back surface of the interior material can be provided. In this case, when the ceiling trim is sandwiched between the functional part main body and the design part, the elastic member is pressed against the ceiling trim.

  In addition, a lid that opens the inside of the functional unit main body is integrally formed with the functional unit main body via a thin hinge, and the thin hinge is the functional unit main body when the lid closes the functional unit main body. It can be configured to function as the elastic member by protruding toward the back surface of the interior material.

  In this case, since the hinge can also be used as an elastic member, the number of parts can be reduced and the cost can be reduced.

  Further, the end portion on the functional part main body side of the thin hinge is formed so as to protrude from the functional part main body toward the back surface of the interior material, and the end part on the lid part side of the thin hinge is formed, It can form so that it may protrude from the said cover part along the extension plane of the surface in the said cover part.

  In this case, although the thin hinge is thin, good elasticity can be provided.

  Furthermore, the bending strength of the end on the functional unit main body side of the thin hinge can be made higher than the bending strength of the end on the lid side of the thin hinge.

  In this case, the end of the thin hinge on the side of the functional unit main body has a relatively large curved shape, and this portion protrudes relatively large from the functional unit main body. Therefore, this protrusion can be suitably used as an elastic member.

  According to the present invention, since only one clip needs to be provided in order to attach the interior illumination lamp to the ceiling trim, the interior illumination lamp can be reduced in size.
