本発明は、光源を装着するための光源用取付孔と、車体に固定するための車体取付部とを有する合成樹脂製のランプボディを備えた車両用灯具に関する。   The present invention relates to a vehicular lamp including a synthetic resin lamp body having a light source mounting hole for mounting a light source and a vehicle body mounting portion for fixing to a vehicle body.

従来の車両用灯具の一例として、車体取付部に端縁リブ、縦リブおよび横リブを設けた車両用灯具が知られている（例えば、特許文献１参照）。   As an example of a conventional vehicular lamp, a vehicular lamp in which an edge rib, a vertical rib, and a horizontal rib are provided on a vehicle body mounting portion is known (for example, see Patent Document 1).

従来の車両用灯具の他の一例として、ランプボディであるハウジングの一部（開口縁部）に、ガスインジェクションにより空間部を形成した車両用灯具が知られている（例えば、特許文献２参照）。
実開平６−７５８８５号公報 特開平１０−３３４７０７号公報 As another example of a conventional vehicle lamp, a vehicle lamp in which a space portion is formed by gas injection in a part (opening edge portion) of a housing that is a lamp body is known (see, for example, Patent Document 2). .
Japanese Utility Model Publication No. 6-75885 Japanese Patent Laid-Open No. 10-334707

近年、車両用灯具のランプボディに装着される部品点数の増加に伴い、車体への取り付けを行う車体取付部への負荷が増大している。そのため、車体取付部の剛性を向上させる必要があり、車体取付部の大型化や重量化が、ランプボディ全体の大型化や重量化を招いていた。   In recent years, with an increase in the number of parts to be mounted on a lamp body of a vehicular lamp, a load on a vehicle body mounting portion for mounting on a vehicle body has increased. Therefore, it is necessary to improve the rigidity of the vehicle body mounting portion, and the increase in size and weight of the vehicle body mounting portion has led to the increase in size and weight of the entire lamp body.

上記特許文献１に開示された車両用灯具では、車体取付部の強度確保のための端縁リブ、縦リブおよび横リブ等の補強リブが設けられているが、車体取付部の重量化に繋がってしまっていた。   In the vehicular lamp disclosed in Patent Document 1 described above, reinforcing ribs such as edge ribs, vertical ribs and horizontal ribs for securing the strength of the vehicle body mounting portion are provided, but this leads to an increase in weight of the vehicle body mounting portion. It was.

また、上記特許文献２に開示された車両用灯具では、ランプボディの開口縁部の見掛け上の厚肉化は維持できるが、光源用取付孔であるバルブ挿入開口の周辺や車体取付部の剛性向上までには至っていなかった。   In addition, in the vehicular lamp disclosed in Patent Document 2, the apparent thickness of the opening edge portion of the lamp body can be maintained, but the rigidity of the periphery of the bulb insertion opening, which is the light source mounting hole, and the rigidity of the vehicle body mounting portion can be maintained. It did not lead to improvement.

本発明は、上述した事情に鑑みてなされたものであり、ランプボディの軽量化および剛性の向上を図ることができる車両用灯具を提供することを目的とする。   The present invention has been made in view of the above-described circumstances, and an object thereof is to provide a vehicular lamp that can reduce the weight and improve the rigidity of a lamp body.

本発明に係る上記目的は、少なくとも光源を装着するための光源用取付孔と、車体に固定するための車体取付部とを有する合成樹脂製のランプボディを備えた車両用灯具であって、
前記ランプボディは、少なくとも前記光源用取付孔の周辺又は前記車体取付部に補強リブが立設されており、該補強リブの内部に中空部を有していることを特徴とする車両用灯具により達成される。 The object of the present invention is a vehicle lamp comprising a synthetic resin lamp body having at least a light source mounting hole for mounting a light source and a vehicle body mounting portion for fixing to a vehicle body,
The lamp body has a reinforcing rib standing at least around the light source mounting hole or the vehicle body mounting portion, and has a hollow portion inside the reinforcing rib. Achieved.

上記構成の車両用灯具によれば、光源用取付孔の周辺又は車体取付部に立設されている補強リブの内部に中空部が形成されているので、補強リブにより剛性の向上を図ることができるとともに、補強リブ内部の中空部によりランプボディの軽量化を図ることができる。特に、光源用取付孔の周辺に補強リブが設けられている場合、重量化を抑えつつ剛性を向上させることができる。これにより、ランプボディが、例えば、エイミング部材自体の重量やエイミング調整時に加わる負荷等により変形するようなことはない。   According to the vehicular lamp having the above configuration, since the hollow portion is formed around the light source mounting hole or inside the reinforcing rib standing on the vehicle body mounting portion, the rigidity can be improved by the reinforcing rib. In addition, the weight of the lamp body can be reduced by the hollow portion inside the reinforcing rib. In particular, when a reinforcing rib is provided around the light source mounting hole, the rigidity can be improved while suppressing weight. Thereby, the lamp body is not deformed by, for example, the weight of the aiming member itself or a load applied during aiming adjustment.

また、上記構成の車両用灯具において、前記中空部は、複数の前記補強リブ内に形成され、隣設された複数の該中空部間が中空連結リブ内の連通中空部によって連通されていることが望ましい。 Further, in the vehicular lamp with the above configuration, the hollow portion is formed in a plurality of said reinforcing the ribs, that between the plurality of hollow portions which are provided adjacent are communicated by the communicating hollow portion in the hollow connecting rib Is desirable.

このような構成の車両用灯具によれば、隣設された中空部間が中空連結リブ内の連通中空部によって連通されているので、重量化を抑えつつ更なる剛性の向上を図ることができる。
特に、光源用取付孔周辺の補強リブ内の中空部と、車体取付部の補強リブ内の中空部とが中空連結リブによって連結されている場合、ランプボディ全体で剛性の向上を図ることができる。すなわち、例えば、光源用取付孔の周辺に加わる負荷を車体取付部の補強リブでも受けることができ、負荷を分散させることができる。 According to such a configuration vehicular lamp, because between the hollow portion which is provided adjacent are communicated by the communicating hollow portion in the hollow connecting rib, it is possible to further improve the stiffness while reducing weight of .
In particular, when the hollow portion in the reinforcing rib around the light source mounting hole and the hollow portion in the reinforcing rib of the vehicle body mounting portion are connected by the hollow connecting rib, the rigidity of the entire lamp body can be improved. . That is, for example, a load applied to the periphery of the light source mounting hole can be received by the reinforcing ribs of the vehicle body mounting portion, and the load can be distributed.

また、上記構成の車両用灯具において、前記中空部は、前記ランプボディ成形時に、前記補強リブ内に連通する成形ガス供給孔から成形ガスが供給されることにより形成されることが望ましい。   In the vehicular lamp configured as described above, it is preferable that the hollow portion is formed by supplying a molding gas from a molding gas supply hole communicating with the reinforcing rib when the lamp body is molded.

このような構成の車両用灯具によれば、ランプボディ成形時の樹脂射出後に、補強リブ内に連通する成形ガス供給孔から成形ガスが供給される、所謂、ガスインジェクション成形により、例えば、車体取付部等を射出成形しながら補強リブ内に中空部を形成することができる。したがって、ランプボディの軽量化と剛性の向上を図ることができる。   According to the vehicular lamp having such a configuration, after injection of the resin at the time of molding the lamp body, a molding gas is supplied from a molding gas supply hole communicating with the reinforcing rib. A hollow part can be formed in the reinforcing rib while injection molding the part or the like. Therefore, the lamp body can be reduced in weight and rigidity.

本発明に係る車両用灯具によれば、ランプボディの光源用取付孔の周辺又は車体取付部に立設されている補強リブの内部に中空部が形成されているので、ランプボディの剛性向上を図りつつ軽量化を図ることができる。   According to the vehicular lamp according to the present invention, since the hollow portion is formed around the light source mounting hole of the lamp body or inside the reinforcing rib standing on the vehicle body mounting portion, the rigidity of the lamp body is improved. The weight can be reduced while being planned.
