Since these engaging operations are guided by the rotation of the rotating portion 27, it is not particularly necessary to perform positioning or the like, and can be easily engaged even if the engaging portion is not visible. At this time, the edge of the mounting hole 31, that is, the roof trim 3, the second side wall of the flange portion 24 and the rotating portion 27 that generate elastic restoring force in the direction of pressing the roof trim 3 toward the indoor side. 29. In this way, the lens 4 is attached to the roof trim 3, the functional unit 2 is locked in the attachment hole 31, and the lamp unit 5 is attached to the roof trim 3. In this state, the valve 51 is opposed to a portion between the pair of rails 43.

  Furthermore, when removing the functional part 2 from the roof trim 3, the jigs are inserted between the locking receiving part 60 and the locking projection 25 from the vehicle body panel side of the mounting hole 31 to engage them. By releasing, it can be easily removed.

  According to the present embodiment, by positioning the rotating portion 27 at the insertion position, the rotating portion 27 and the main body portion 21 can be passed through the mounting hole 31 from the vehicle body panel side toward the indoor side and rotated. After the portion 27 is passed through the mounting hole 31, the edge of the mounting hole 31 is sandwiched between the rotating portion 27 and the flange portion 24 by being positioned at the locking position by the elastic restoring force of the hinge 26 and the rail 43. Thus, the housing 20 of the functional unit 2 can be attached to the roof trim 3. Therefore, the functional unit 2 can be passed in the vertical direction without being inclined with respect to the mounting hole 31, and can be easily attached to the roof trim 3. Furthermore, since the functional portion 2 can be easily attached to the roof trim 3 only by the operation of pushing the functional portion 2 into the attachment hole 31 in the vertical direction, this attachment operation can be mechanized. Moreover, since the conducting wire of the function part 2 in this attachment work can be made shortest, the electric wire 53 connected with the function part 2 can be made into the required minimum length. Therefore, the fixing work of the electric wire 53 performed after the lamp unit 5 is attached to the roof trim 3 can be omitted or simplified.

  Further, since the edge of the mounting hole 31, that is, the roof trim 3 can be sandwiched and fixed between the rotating portion 27 using the elastic restoring force of the flange portion 24, the flange portion 24 and the rotating portion 27 and the roof trim are fixed. It is possible to prevent the backlash from being generated between the functional part 2 and a plurality of types of vehicles having different thicknesses of the roof trim 3.

  In the above-described embodiment, the rotating portion 27 is connected to both edges in the longitudinal direction of the bottom wall 22. However, in the present invention, it is sufficient that at least one rotating portion 27 is provided. . Moreover, the rotation part 27 may be provided in the edge of the width direction of the bottom wall 22, and may be provided in the edge of both the width direction and a longitudinal direction.
