This metal covering 92M be located at brake lamp 52 top and with the position of brake lamp 52 subtend, more specifically, more more rearward than the center C1 of the bulb 53 of brake lamp 52 viewed from vehicle body side and that the direct light (representing with single dotted broken line Fig. 7) irradiated rearwardly and upwardly from bulb 53 is incident position is located at.

Lenticular unit 93 is formed by the red, transparent material homochromy with the illuminant colour of brake lamp 52 and is fixed on substrate parts 92, to cover the metal covering 92M of this substrate parts 92 from rear.

This lenticular unit 93 has sees forwards open bowl shape at vehicle body side, and holds around it and be fixed on this substrate parts 92 entering under the state in the recess 92C (with reference to Fig. 5 and Fig. 7) crossing and form and formed around the longitudinal wall part 92A of substrate parts 92.

As shown in figure 5 and figure 7, because lenticular unit 93 to cover the back side of substrate parts 92, completely so can not see this substrate parts 92 from car body rear and only can see lenticular unit 93 from rear from rear.

Thus, because false high-position lamp 91 to be arranged on rear handle 71 and to have the red lens parts 93 can seen from rear, thus can obtain with when the vehicle rear handle 71 being provided with high-position lamp due to engine stop etc. and taillight extinguishes time identical outward appearance.And lenticular unit 93 has been implemented lens cutting not shown in the figures, utilizes these lens to cut, the outward appearance identical with the light fixture such as high-position lamp can be obtained.

And, owing to there is the metal covering 92M with the convex strip portions 92B of substrate parts 92 in lenticular unit 93, so when seeing in lenticular unit 93, this metal covering 92M can realize the outward appearance similar to the inner structure (reflector structure) of the light fixtures such as high-position lamp.Even if from du vehicule, also the outward appearance identical with the vehicle that high-position lamp is housed can be obtained.

In addition, because this lenticular unit 93 can pass through light, so can pass through from the light of brake lamp 52, and make the metal covering 92M of the incident substrate parts 92 of this light.Thereby, it is possible to utilize this metal covering 92M that light is rearward reflected, utilize lenticular unit 93 make this reflected light become red and irradiate to car body rear.

In detail, as shown in figure 5 and figure 7, reflect towards the light of the front end of the convex strip portions 92B of metal covering 92M owing to utilizing the circle of this front end from the light of brake lamp 52 incidence, thus easily to car body rear reflection and this reflected light can identify from rear.On the other hand, from the light of brake lamp 52 incidence towards the light beyond the front end of the convex strip portions 92B of metal covering 92M owing to reflecting downwards under this convex strip portions 92B, so can not identify from rear.In addition, recessed bar portion 92F that is recessed to car body front and that extend along vehicle-width direction is formed between each convex strip portions 92B.This recessed bar portion 92F forms dark portion and can produce light and shade difference.

Thus, from car body rear can identify Line of light that the front end along each convex strip portions 92B extends at vehicle-width direction, each convex strip portions 92B can be identified front end between namely 92F place, recessed bar portion dark portion and can identify that light and shade is poor.Thus, when brake lamp 52 is lighted, three wire red light equal with the quantity of convex strip portions 92B are identified by from car body rear across compartment of terrain in the vertical direction.

So when brake lamp 52 is lighted, this false high-position lamp 91 can utilize the light of this brake lamp 52 rearward to irradiate red light, and with the same with the situation of the bright high-position lamp in brake lamp phase interlock place, identity during brake operating can be improved.

And, due to this false high-position lamp 91 for many wire red light are identified across interval up and down, so the outward appearance as being built-in with wire light emitting source can be realized, and outward appearance extremely similar when can realize lighting to high-position lamp.Thus, light emitting source is not adopted just can to realize the function identical with high lamp brake lamp and same outward appearance.

As above illustrated, in this structure, handle 71 after having above the brake lamp 52 forming taillight 51, and have as rearward reflecting the false high-position lamp 91 worked from the reflecting part of the light of brake lamp 52 in the bottom of this rear handle 71.Due to this false high-position lamp 91 be installed into brake lamp 52 in opposite directions and there is substrate parts (reflection part) 92 and lenticular unit 93, this substrate parts (reflection part) 92 has the metal covering 92M of the light rearward reflected from brake lamp 52, this lenticular unit 93 cover substrate parts 92 metal covering 92M and through light, so the structure not possessing light emitting source can be utilized rearward luminous by lighting of taillight 51, can when high-position lamp is lighted in the same manner as improve identity, even and if also the outward appearance same with the light fixture with light emitting source can be obtained when brake lamp extinguishes by day.

Even if thereby, it is possible to utilize simple structure also to obtain the excellent outward appearance of the identity same with high-position lamp when taillight extinguishes, and compared with adopting the situation of light fixture, number of components can be reduced and reduce price.In addition, owing to utilizing metal covering 92M to reflect, so aesthetic appearance can be improved and more effectively reflected light.

In addition, in this structure, because metal covering 92M has the convex strip portions 92B for the formation of the stage portion extended along vehicle-width direction, thus can rearward send extend along this stage portion at vehicle-width direction light, can realize as the outward appearance be built-in with wire light emitting source and can aesthetic appearance be improved.

In addition, the convex strip portions 92B arranging multiple and more top side across compartment of terrain in the vertical direction due to convex strip portions 92B is more outstanding to car body rear, so can rearward send in the vertical direction across interval and many light extended in the vehicle width direction, and form dark portion between this convex strip portions 92B, the further identity improved from outside of light and shade difference can be utilized, improve aesthetic appearance further.

In addition, because the front end of convex strip portions 92B sees to have circular section segment in side, utilize the circle of this front end, easily the light from brake lamp 52 to car body rear reflection, reliably can improve the identity from car body rear.

And, because the front end of convex strip portions 92B is formed in vehicle-width direction central authorities by the left and right extended end portion 92B1 that linearity extends in the lateral direction and is formed by the inclined end portion 92B2 more more forwards tilted outside vehicle-width direction outside vehicle-width direction, so can be luminous to car body rear and in the broad range of vehicle-width direction, the identity in the broad range of car body rear can be improved.

In addition, in this structure, due to the illuminant colour of taillight 51 and the solid colour of lenticular unit 93, so the identity that the color light identical with taillight 51 also can improve taillight 51 can be sent.In the case, owing to making the color of the illuminant colour of brake lamp 52 and lenticular unit 93 be redness, so the identity of brake lamp 52 can be improved.

In addition, in this structure, as shown in Figure 5, bulb center C1 due to taillight 51 is configured to more closer to the front than the front end of the substrate parts 92 with metal covering 92M, so with substrate parts 92 is configured in directly over the C1 of bulb center or compared with the situation in front, the luminous intensity distribution making taillight 51 is not needed to spread, therefore, it is possible to reduce the horsepower output of this taillight 51 itself.

And, in above-mentioned configuration, as shown in figure 5 and figure 7, and substrate parts 92 to be configured in directly over the C1 of bulb center or compared with the situation in front, incidence angle θ 1 can be increased.Because incidence angle θ 1 is larger, light reflectance is larger, so can strengthen the reflection of rearward light.That is, in this structure, owing to making reflecting surface be metal covering 92M, so can surface reflectivity be improved, and utilize above-mentioned configuration, also can improve reflectivity, can more effectively rearward reflected light.Thus, even if hypothesis makes the thickness of metal covering 92M thin, also enough light can rearward be launched.Wherein, in the figure 7, symbol theta 2 represents angle of reflection.
