In addition, the confirmation window 50B is penetrated in a direction that rises and slopes toward the front of the vehicle. For this reason, it is easy to insert the finger of the left hand into the confirmation window 50B from obliquely below.

  Further, by inserting a finger into the confirmation windows 50A and 50B, the vehicle interior side of the switch base 40 can be supported by the finger, and the switch base 40 can be gripped more reliably.

  Next, the operator causes the switch base 40 to approach the mounting claws 32 of the lower board 22 from the outside of the passenger compartment, and inserts the mounting claws 32 into the insertion holes 46A.

  In the process in which the attachment claw 32 is inserted through the insertion hole 46A, the contact surface 33 of the attachment claw 32 contacts the edge of the insertion hole 46A in the vehicle interior side wall 46 as shown in FIG. Thereby, when the contact surface 33 is pressed by the hole edge part of 46 A of insertion holes, the front end side of the attachment nail | claw 32 bends and deform | transforms upwards by using a base end as a fulcrum.

  In addition, since the vehicle interior side wall 46 is supported from the outside of the vehicle compartment by the support wall 47, the contact surface 33 can be reliably pressed without being deflected and displaced outside the vehicle compartment.

  And when the front-end | tip part 32A of the attachment nail | claw 32 passes 46A of insertion holes, as shown in FIG. 7, the attachment nail | claw 32 will return elastically. As a result, the locking surface 34 of the mounting claw 32 is locked from the outside of the passenger compartment to the edge of the insertion hole 46A. As a result, the attachment claw 32 is restricted from being removed from the insertion hole 46 </ b> A, and the switch base 40 is attached to the attachment claw 32.

  Simultaneously with the attachment to the attachment claw 32, an attachment boss (not shown) formed on the back surface of the decorative panel 26 is inserted into the attachment hole 45A of the switch bezel 42. The mounting boss inserted through the mounting hole 45A is fastened to the mounting piece 45 by fastening means such as heat caulking and screws.

  Next, the effect of this embodiment will be described.

  Thereby, the operator can check the state of the mounting claw 32. Specifically, as shown in FIG. 7, the distal end portion 32 </ b> A of the attachment claw 32 inserted through the insertion hole 46 </ b> A is disposed in a space S <b> 1 surrounded by the support wall portion 47.

  For this reason, by inserting a finger into the space S <b> 1 through the confirmation window 50 </ b> B (or 50 </ b> A), the tip of the tip 32 </ b> A of the mounting claw 32 can be touched. Thereby, it can be confirmed that the mounting claw 32 is inserted into the insertion hole 46A, and that the tip 32A of the mounting claw 32 is locked to the hole edge of the insertion hole 46A.

  Further, when the switch base 40 is attached, the switch base 40 can be gripped more reliably by inserting a finger into the confirmation windows 50A and 50B. If the confirmation windows 50A and 50B are not formed, it is difficult to insert a finger into the small gap between the switch base 40 and the lower board 22, and the operator supports the switch base 40 from the vehicle interior side. It is difficult. In this case, for example, it is conceivable that the operator performs the attaching operation by grasping the lower end portion of the switch main body 30.

  However, when the switch main body 30 is gripped at the time of attachment, a load acts on the switch main body 30 that is an electronic component, which is not preferable. In the present embodiment, the switch base 40 can be supported from the vehicle interior side by inserting a finger into the confirmation windows 50A and 50B, and it is preferable that the switch main body 30 does not need to be gripped.

  Further, when the switch base 40 is mounted with the fingers inserted into the confirmation windows 50A and 50B, the tip 32A of the mounting claw 32 and the tips of the pair of positioning ribs 35 and 35 are inserted into the insertion hole 46A. At this point, the operator can touch these tips with a finger. Thereby, it can be confirmed that the positioning of the mounting claw 32 and the insertion hole 46A is correctly performed during the mounting operation, and the mounting operation can be performed more reliably.
