DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tail lamp device for a vehicle such as a motorcycle.

[0002]

2. Description of the Related Art Generally, a tail lamp of a vehicle is floatingly attached to a vehicle body member via cushion rubber or the like in order to reduce a vibration acceleration applied thereto, and a surrounding portion is covered with a cover member.

[0003] When the tail lamp is mounted on the body member in a floating manner, the vibration acceleration is reduced, but the amplitude tends to increase instead. When the amplitude is large, the tail lamp hits the cover member. Since a large acceleration is generated, a predetermined gap (clearance) is provided between the tail lamp and the cover member. In particular, in a motorcycle, the tail lamp easily vibrates in the vertical direction, so that the vertical gap is important.

Japanese Unexamined Patent Publication No. 5-105140 discloses a bracket attached to the rear part of a vehicle body in order to prevent the tail lamp mounted as described above from falling due to weight or the like, so that the upper and lower gaps with the cover cannot be made uniform. Attach the front end of the tail lamp to the vertical wall with cushion rubber, sandwich the cushion rubber between the upper and lower walls on the rear side of the vertical wall and the upper and lower surfaces of the tail lamp, and attach the upper and lower tail covers to the upper and lower walls of the bracket A motorcycle tail lamp device is disclosed in which the upper and lower edges of the side cover are fastened to each other and the upper and lower edges of the rear portion of the side cover are fitted and connected to each other.

[0005]

In the above-described tail lamp device, the upper and lower gaps between the tail cover and the tail lamp can be kept uniform. However, in order to make the left and right gaps uniform, a plurality of elastic members are required. And the number of parts and the number of assembling steps increase.

That is, as shown in FIG. 1A, if the tail lamp 01 has a shape having upper and lower horizontal sides a, a and both side sides b, b perpendicular thereto, the upper and lower gap α ,
By simply setting α to a predetermined value, it is possible to prevent the tail lamp 01 from hitting the cover 02 due to the vertical vibration of the tail lamp 01. However, this is not always the case when both sides b, b are inclined with respect to the upper and lower horizontal sides a, a as shown in FIG. 1 (b).

This is because the cover 02 is displaced in the left-right direction with respect to the tail lamp 01, and as shown in the enlarged view of FIG. When the tail lamp 01 vibrates in the vertical direction when approaching the side b, the side b hits the opening edge c ′ before the upper side a hits the upper opening edge d of the cover 02, thereby causing the tail lamp 01 to have a large acceleration. (Force) will be added. That is, the minimum clearance α in the vertical direction of the tail lamp 01 decreases to β.

Further, the tail lamp device has a complicated structure of a bracket and a large number of parts, which increases the number of assembling steps and costs. Furthermore, replacement of the bulb is also difficult. That is, since there are many brackets on the front vehicle body side, they become an obstacle when replacing the bulb from the front, and when replacing from behind, the lens cannot be removed without removing the side cover.

Accordingly, the present invention is to improve such a conventional tail lamp device and to provide a tail lamp device which overcomes the above-mentioned problems.

[0010]

According to the present invention, a tail lamp is mounted on a vehicle body in a space surrounded by a tail cover covering a rear portion of the vehicle body, and a lens surface of the tail lamp is provided. In a tail lamp device for a vehicle facing a window hole provided on a rear surface of the tail cover, a lens of the tail lamp and the tail cover are engaged with each other via an elastic body at a position hidden from behind by the tail cover. An engaging portion to be provided is provided.

According to the present invention, by engaging the tail lamp lens with the tail cover via the engaging portion,
Since both are positioned relatively not only in the vertical direction but also in the horizontal direction, a uniform gap can be secured over the entire circumference of the lens, and the appearance is improved. The displacement in the left-right direction does not limit the clearance for the vertical vibration of the tail lamp.

Since the elastic portion is interposed in the engaging portion, the vibration-proof effect of the tail lamp floatingly attached to the vehicle body member is not lost by the engaging portion.
In addition, since the relative amplitude between the window hole and the lens is reduced by this engagement, the gap can be reduced, and a better appearance can be obtained.

Further, the tail lamp device of the present invention does not require a bracket or the like having a complicated structure as in the above-described conventional tail lamp device, and therefore, the cost can be reduced with a simple shape and configuration.

The engaging portion is constituted by a convex portion and a concave portion which are fitted to each other, and the elastic body is attached to the tip of the convex portion, so that the configuration of the tail lamp device is further simplified and the assembling work is simplified. It can be easier.

Further, if the rear surface of the tail cover is divided and formed by a detachable single member, the bulb can be replaced very easily from the rear by removing this member.

In the present embodiment, the lens 57 of the tail lamp 36 and the rear panel 21 are engaged with each other via the engaging portion formed by the engaging concave portion 63 and the engaging convex portion 64, so that both of them are vertically movable. Since the positioning is relatively performed in the left-right direction, a predetermined uniform gap can be secured between the lens surface 59 and the edge of the window hole 15 of the rear panel 21 over the entire circumference. Accordingly, the appearance is improved, and the clearance with respect to the vibration of the tail lamp 36 is not restricted by the small portion of the gap. That is, the tail lamp 36 does not hit the rear panel 21 when vibrating and receives a large acceleration, so that the life of the filament of the bulb 58 is prolonged.

Since the elastic body 65 is interposed in the engaging portion, the vibration-proof effect of the tail lamp 36 floatingly mounted via the mount rubber 51 is not lost by the engaging portion. In addition, since the relative amplitude between the window hole 15 and the lens 57 is reduced by this engagement, the gap can be reduced, and a better appearance can be obtained.

Since the engaging portion is provided at a position hidden by the rear panel 21, the appearance is not impaired.

In this embodiment, since the seat lock body 24 exists in front of the tail lamp 36, it is difficult to replace the light bulb 58 from the front.
Since it is constituted by the engaging concave portions 63 and the engaging convex portions 64 arranged on a straight line, the mounting and dismounting of the rear panel 21 are easy, and the light bulb 58 can be replaced very easily from behind. When replacing the light bulb, from the rear of the vehicle body, if the three screws 28 holding the rear panel 21 are removed and the rear panel 21 is moved rearward, the engaging convex portion 64 comes out of the engaging concave portion 63. After removing the rear panel 21, remove the lens mounting screw 56 and remove the lens 57 to easily
58 can be removed. Since the elastic body 65 is fixed to the engaging convex portion 64 and enters and exits the engaging concave portion 63 integrally with the engaging convex portion 64, there is no possibility that the elastic body 65 falls off and is lost when the rear panel 21 is removed, In addition, when the rear panel 21 is attached, there is no need to insert the elastic body 65 between the engaging concave portion 63 and the engaging convex portion 64, and the rear panel 21 can be easily removed.

In addition, the tail lamp device of this embodiment
The mounting structure to the vehicle body is simple, the work of assembling the tail lamp is easy, and there are many effects such as a reduction in cost.

Although a preferred embodiment of the present invention has been described above, the present invention is not limited to this, and it goes without saying that many modifications are possible within the scope of the present invention.

For example, in the above embodiment, the lens 57
Although the engaging concave portion 63 is provided on the rear panel 21 and the engaging convex portion 64 is provided on the rear panel 21, the engaging convex portion may be provided on the lens side and the engaging concave portion may be provided on the rear panel side. Further, the elastic body 65 may be fixed to the engaging recess 63 side, and further, when the bulb replacement is performed from the front side, and the rear panel does not need to be detached and attached for this purpose, the elastic body may be fixed to the convex portion or the concave portion. It is also possible not to stick to the side.

Further, the tail lamp 36 in the above embodiment is used.
Is a two-lamp type having a pair of right and left bulbs 58 and a lens surface 59, but it may be a single-lamp type. It may be provided.

Further, the present invention is applicable not only to motorcycles but also to various vehicles such as motorcycles and automobiles.
