The formation position of the drop portion 15 and the close contact portion 18 is set and configured (the accuracy of the formation position of the slide portion 14, the drop portion 15 and the close contact portion 18 is determined by resin molding). In order for the sliding portion 14 to exhibit a good sagging and sliding action with respect to the concave step surface 17 having a right angle, the sliding portion 14 is also in contact after the close contact portion 18 comes into close contact with the lower end surface of the hole edge of the mounting hole portion 8. A good slidable sliding action that attempts to slide down and slide into the sagging portion 15 is continuously exerted, and the close contact portion 18 keeps in close contact with the lower end surface of the hole edge of the mounting hole portion 8 to seal the mounting hole portion 8. It is set as the structure by which a state is maintained favorable. Note that the sagging portion 15 may be formed on a descending inclined surface that inclines descending toward the insertion base end side of the insertion portion 7 so that the sliding portion 14 exhibits a satisfactory sagging sliding action.

  Further, in this embodiment, the close contact portion 18 collides with the vicinity of the hole edge of the mounting hole portion 8 due to the drop sliding action in which the slide portion 14 tries to slide down into the drop portion 15 and is notified as “click”. It is configured to generate a sound (impact sound between synthetic resins), and due to the generation of this notification sound, the contact portion 18 is in close contact with the vicinity of the hole edge of the mounting hole portion 8 and the mounting hole portion 8 is securely sealed. Is configured to be recognized by the user.

  Note that the present invention is not limited to this embodiment, and the specific configuration of each component can be designed as appropriate.
