Since the inclined edge 35 is pressed by the rear edge of the mounting hole 38, the engaging plate 33 receives the upward and forward moving force. Since the upper edge of the engaging plate 33 contacts the lower surface of the holding projection 16 formed on the lamp body 3 and is prevented from moving further upward, the elastic piece 32 on which the engaging plate 33 is formed is formed. The S-shaped portion is bent so as to shrink in the front-rear direction, and the engagement plate 33 moves forward. Thereby, the mounting hole 38
The rear edge moves the inclined edge 35 of the engagement plate 33 relatively upward and engages with the engagement notch 34. In this way, the high-mount stop lamp 1 is mounted on the partition plate 37 inside the rear windshield 2. Incidentally, the high mount stop lamp 1 may be attached to the partition plate 37 by means such as screwing.
