Abstract

In a conventional lamp for vehicles, there may be a case in which any shuddering is generated. The present invention comprises a semiconductor-type light source, a lens, a lens holder, and a heat sink member. An attachment hook section is provided in the lens holder. Attachment sections are provided in the heat sink member. The attachment sections of the heat sink member are interposed between the lens holder and the attachment hook section. The present invention is capable of attaching the lens holder to the heat sink member without any shuddering being generated.

First claim

The invention claimed is:

1. A lamp for vehicles, comprising:
a light source;
an attachment member; and
an attached member, wherein
at the attachment member and the attached member, attachment structures to attach the attached member to the attachment member are respectively provided,
the attachment structures each comprises:
an attachment section which is provided at least at either one of the attachment member and the attached member, and which has an insertion space section; and
an attachment hook section which is provided at least at another one of the attachment member and the attached member to attach the attached member to the attachment member, and which corresponds to the attachment section, the attachment hook section being configured such that, when being inserted in an insertion direction into the insertion space of the corresponding attachment section and then moved in a direction crossing the insertion direction, the attachment hook section and said another one of the attachment member and the attached member at which the attachment hook section is provided, interpose the corresponding attachment section therebetween in the insertion direction and an opposite direction thereof by way of a mutual abutment between the corresponding attachment section and each of the attachment hook section and said another one of the attachment member and the attached member.

2. The lamp for vehicles, according to claim 1 , wherein the attachment hook section comprises:
an interposing section which is provided to oppose to at least at said another one of the attachment member and the attached member, and which interposes the attachment section; and
a positioning section which is provided in the movement direction between at least said another one of the attachment member and the attached member and the interposing section, and which abuts against an edge at the movement direction side of the insertion space section and then determines a position in the movement direction.

3. The lamp for vehicles, according to claim 2 , wherein, at said another one of the attachment member and the attached member, in a state in which the positioning section abuts against the edge at the movement direction side of the insertion space section, there is provided a slip stop section to abut against an opposite edge to the edge at the movement direction side and then determine an opposite position to the movement direction and then stop the attachment hook section from slipping off from the attachment section.

4. The lamp for vehicles, according to claim 2 , wherein the positioning section and the edge at the movement direction side of the insertion space section against which the positioning section abuts are provided at least by two in a direction crossing the insertion direction and the movement direction.

5. The lamp for vehicles, according to claim 4 , wherein the movement direction is a direction crossing a gravitational direction.

6. A lamp for vehicles, comprising:
an attachment member to which a light source is attached;
an attached member; and
an attachment structure to attach the attached member to the attachment member,
wherein the attachment structure comprises:
an attachment section which is provided at least at either one of the attachment member and the attached member, and which has an insertion space section; and
an attachment hook section which is provided at least at another one of the attachment member and the attached member to attach the attached member to the attachment member and which corresponds to the attachment section, the attachment hook section being configured such that, when being inserted in an insertion direction into the insertion space section of the corresponding attachment section, and then moved in a direction crossing the insertion direction, the attachment hook section and said another one of the attachment member and the attached member at which the attachment hook section is provided, interpose the corresponding attachment section therebetween in the insertion direction and in an opposite direction thereof by way of a mutual abutment between the corresponding attachment section and each of the attachment hook section and said another one of the attachment member and the attached member,
wherein the attachment structure is provided in plurality,
wherein, in a front view, the light source is positioned inside of a plurality of the attachment structures, and
wherein, in a front view, distances between the respective attachment structures and the light source are substantially equal to each other.

7. The lamp for vehicles, according to claim 6 , wherein the attachment hook section is provided at least by one in a direction crossing the movement direction, and comprises:
a rising plate section which is provided to rise in the insertion direction from at least another one of the attachment member and the attached member;
an interposing plate section which is extended from the rising plate section in the movement direction, and which interposes the attachment section between the interposing plate section and at least said another one of the attachment member and the attached member; and
a reinforcement plate section which is provided at one side of a respective one of the rising plate section and the interposing plate section, said one side being at a symmetrical position with respect to the movement direction.

8. A lamp for vehicles, comprising:
a light source;
a first member; and
a second member, wherein
attachment structures to attach the first member to the second member are respectively provided at the first member and the second member,
each of the attachment structures comprises:
an attachment section, provided at least at one of the first member and the second member, and having an insertion space section; and
an attachment hook section provided at least at another one of the first member and the second member,
the attachment hook section configured to attach the first member to the second member, and corresponding to the attachment section,
the attachment hook section configured such that, when inserted in an insertion direction into the insertion space of the corresponding attachment section and then moved in a direction crossing the insertion direction, the attachment hook section and said another one of the first member and the second member at which the attachment hook section is provided, interpose the corresponding attachment section therebetween in the insertion direction and an opposite direction thereof by way of a mutual abutment between the corresponding attachment section and each of the attachment hook section and said another one of the first member and the second member.
