する。 In order to achieve the above object, the present invention involves fitting a lens into a stepped opening provided in a rim, and attaching and bonding the legs provided around the lens to the stepped portion. The vehicle lamp is characterized in that a light-shielding wall is integrally formed on the inner peripheral side of the stepped opening, and the tip of the light-shielding wall is brought into contact with the periphery of the light-emitting portion of the lens. Next, an embodiment of the present invention will be described with reference to FIGS. 3 and 4. FIG. 3 shows a vertical cross section of the vehicle lamp according to the present invention, and corresponds to FIG. 1 of the conventional device. FIG. 4 also shows a horizontal cross section and corresponds to FIG. 2 of the conventional device.

リム１を不透明な合成樹脂でモールド成形する。
これに伴つて上記の遮光壁１２も不透明な合成樹
脂によつて形成される。 A light shielding wall 12 is integrally formed on the inner periphery 4 of a stepped opening provided in a rim 1. The light shielding wall 12 is set such that its base end 12a is connected to the inner periphery 4 of the stepped opening of the rim, and its free end 12b is brought into contact with the periphery of the light emitting portion 8 of the lens 7. In this example, the rim 1 is molded from an opaque synthetic resin.
Along with this, the above-mentioned light shielding wall 12 is also formed of opaque synthetic resin.

部に到達することを妨げる。 With the above configuration, as clearly understood from FIGS. 3 and 4, the inner peripheral edge of the opening of the rim 1 is extended substantially toward the light projection direction, and its tip is connected to the lens light emitting section 8. The shape is such that it touches the periphery from the inside. Therefore, the light shielding wall 12 does not prevent the light emitted from the lamp 5 from passing through the lens light emitting section 8, and also covers the peripheral portion other than the light emitting section 8 from the inside so that the light emitted from the lamp 5 passes through the lens. Prevents reaching the periphery.

るためダタつく虞れが無い。 Due to the above-mentioned effect, the light shielding wall 1 in this embodiment
2 has the same light-shielding effect as the light-shielding plate 11 (FIGS. 1 and 2) in a conventional vehicle lamp, and allows only the light-emitting portion 8 of the lens 7 to emit light, without leaking light to the surrounding area. That is understood. Moreover, since the light shielding wall 12 according to the present invention is molded integrally with the rim 1, the parts manufacturing cost is low, no separate assembly work is required, reducing assembly man-hours, and since the light shielding wall 12 is molded as one piece, there is no need for data. There is no risk of it happening.

漏光する虞れが無い。 As explained above, the present invention provides a vehicle in which a lens is fitted into a stepped opening provided in a rim, and the legs provided around the lens are fixed by abutting against the stepped portion. By integrally forming a light-shielding wall on the inner periphery of the above-mentioned stepped opening and bringing the tip of the wall into contact with the periphery of the light-emitting part of the lens, the light fixture has a simple and inexpensive structure that requires less assembly man-hours. To allow a projected light beam to pass only through a light emitting part of a lens without the risk of a member rattling, and to eliminate the risk of light leakage from the peripheral part of the lens.
