Further, as shown in FIGS. 1 and 2, the position of the occupant's hand with the forearm moved to the front of the torso is higher when the occupant's upper body is facing forward than when the occupant's upper body is facing forward. It is above. The return switch 23, which is operated when the occupant's upper body is facing forward and upward, is located behind and above the relaxing switch 22 which is operated when the upper body is facing forward. Therefore, the return switch 23 is easier to operate than when it is located behind or below the relax switch 22.

Since the decorative member 25 is formed of a member that transmits the light emitted from the light emitting element 50, the occupant can visually recognize the light emitted from the inside of the vehicle. Further, by using the capacitance sensor 54, it is possible to detect the touch operation of the occupant on the decorative member 25 without exposing the sensor to the decorative member 25. In this way, since both the switches 22 and 23 are covered from the inside of the vehicle by the decorative member 25, the design of the door 4 is enhanced. Further, since the protrusions 40 and 41 are provided on the outside of the vehicle, the occupant can easily understand the positions of the switches 22 and 23.

The light emitted from the light emitting element 50 enters the vehicle interior 2 from the vehicle outer wall surface of the decorative member 25 facing the opening of the main body 65. Therefore, on the inner wall surface of the car of the decorative member 25, the region located inside the car of the opening of the main body 65 emits light. By forming the main body portion 65 into a cylindrical shape, only the portion facing the opening of the main body portion 65 can emit light, and the light emitting region and the non-light emitting region can be clearly separated. Further, since the light emitting element 50 and the vehicle outer wall surface of the decorative member 25 are separated from each other, the intensity of the light in the region irradiated with the light of the light emitting element 50 can be made more uniform. Further, since the light from the light emitting element 50 is scattered by the diffuser 80, the intensity of the light reaching the region located inside the car inside the opening of the main body 65 is uniform on the car inner wall surface of the decorative member 25. Can be. Therefore, on the inner wall surface of the car of the decorative member 25, the region located inside the car of the opening of the main body 65 can be made to emit light evenly.

Since the capacitance sensor 54 is coupled to the vehicle outer wall surface of the light emitting region of the decorative member 25, the touch on the light emitting region of the occupant can be easily detected by the capacitance sensor 54. Further, by arranging the light-shielding member 52 along the vehicle outer wall surface of the decorative member 25, the diffraction of light is suppressed as compared with the case where the light-shielding member 52 is arranged away from the vehicle outer wall surface. The symbols 60 and 61 of the light-shielding member 52 can be displayed more clearly on the inner wall surface. Further, by providing the vibration motor 53 on the support portion 66, the vibration motor 53 can be brought close to the protrusions 40 and 41, and the vibration can be more effectively transmitted to the occupant's hand.

Although the description of the specific embodiment is completed above, the present invention can be widely modified without being limited to the above embodiment. In the present embodiment, the present invention has been applied to the switching device 16 for switching the position of the vehicle seat 1 in the right front seat, but it may be applied to the switching device for the vehicle seat in the rear seat. Further, although the relax switch 22 and the return switch 23 are both provided on the door trim 26, they may be provided on the trim constituting the inner wall of the vehicle interior 2, for example, the return switch 23 may be provided on the body side trim, more specifically. May be provided in the center pillar garnish between the front door and the rear door.

In the above embodiment, both the switches 22 and 23 are configured by the capacitance sensor 54 that detects the touch of the decorative member 25 by the occupant, but the present invention is not limited to this embodiment, and the decorative member 25 is, for example. It may be a membrane switch or a push type switch provided in.

In the above embodiment, the protrusions 40 and 41 and the plate 39 are integrally molded, but after the protrusions 40 and 41 are molded separately from the plate 39, the protrusions 40 and 41 are formed into a plate. It may be formed by being attached to the portion 39. However, by integrally molding the protrusions 40 and 41 and the plate 39, the bond between the protrusions 40 and 41 and the plate 39 becomes stronger, and the protrusions 40 and 41 and the plate 39 are separated. Can be prevented.

In the above embodiment, the film 37 is formed of a resin having a transparent colored material layer, but it may be a mode in which light from the light emitting element 50 is transmitted, and wood grain or the like may be printed on the surface. Further, although the identification portion 42 is thinner than the other portions, it may be thicker than the other portions. In this case, the film 37 is formed using a resin that shrinks due to heat, the film 37 and the base material 36 are adhered to each other, and then a heater is installed parallel to the surface of the base material 36 to heat the film 37 from the heater. It is preferable to shrink the surface on which the heat of the film 37 is easily transferred, that is, the portion of the film 37 facing the heater. The heating causes the protruding end surface and the portion of the plate 39 in contact with the outer surface of the vehicle to shrink. On the other hand, since the side surfaces of the protrusions 40 and 41 are difficult to transfer heat and shrink, the portion of the film 37 bonded to the side surfaces of the protrusions 40 and 41 is thicker than the other portions. Thereby, the identification portion 42 thicker than the other portions can be formed on the ridge line portion 43 and the outer edge 44.

In the above embodiment, the light emitting element 50 of the relax switch 22 is configured to always light up when the vehicle seat 1 is in the standard position, but after the vehicle seat 1 is in the standard position, a predetermined time is reached.
