  The outer surface that constitutes a part of the vehicle exterior of the rear grip 61 mainly includes the upper surface 63 and a lower surface 64 that extends obliquely downward and inward from the outer edge thereof. Ridge lines (outer edges of the upper and lower surfaces 63 and 64) R where the upper and lower surfaces 63 and 64 intersect form an outer peripheral shape of the rear grip 61 in a top view. In other words, the upper and lower surfaces 63 and 64 are provided so as to reach the outer edges of the rear grip 61 in a top view, respectively. The outer edge of the rear grip 61 in the top view is provided so as to follow the outer peripheral shape in the top view of the rear combination lamp 51 on the outer side.

  The lower surface 64 of the rear grip 61 is inclined so as to be positioned higher on the outer edge side, and the lower surface 64 is formed with a predetermined width over the entire left and right width of the rear grip 61. Hereinafter, although the part which forms the lower surface 64 in the rear grip 61 is demonstrated as the plane part 65, the lower surface 64 is a substantially flat curved surface. That is, the plane portion 65 is a portion that forms a flat surface having a predetermined width and without unevenness, and may be a polygonal shape or a step shape as well as a flat shape.

Here, in the lens 54 of the tail lamp 52 of the rear combination lamp 51, an upper lens 54a capable of distributing the bulb light of the tail lamp 52 also upward is located above the top (vertical middle part) of the convex cross section. Configured as
Above the upper lens 54a, the rear portion of the rear grip 61 protrudes rearward so as to cover the upper lens 54a. That is, the upper lens 54a and the rear portion of the rear grip 61 are provided so as to overlap each other when viewed from above, in other words, facing each other in the vertical direction. As a result, the lower surface 64 of the rear grip 61 inclined rearward is positioned above the upper lens 54a.

Is configured as a reflective surface 64a capable of reflecting the vehicle rearward.
Thus, the light from the tail lamp 52 is directly distributed from the lens 54 and is reflected (distributed) toward the rear of the vehicle on the lower surface 64 of the rear grip 61. In other words, the predetermined range in the plane portion 65 is the reflection portion 65a that forms the reflection surface 64a that reflects the light from the tail lamp 52 toward the rear of the vehicle.

  A groove-like concave portion (rear reflection suppressing portion) 66 having a predetermined depth is formed in a portion of the flat portion 65 near the rear combination lamp 51 (a portion close to the upper lens 54a). The recess 66 extends in the left-right direction over at least the left-right width of the upper lens 54a. For example, the ridge line portion between the lower end facing the lens upper surface and the lower surface 64 in the rear grip 61 is recessed in a circular arc shape. . The concave portion 66 does not reflect the bulb light from the upper lens 54a backward (in other words, suppresses reflection of the bulb light from the upper lens 54a rearward). As a result, when the rear part of the vehicle body is viewed from the rear, the light emission of the lens 54 of the tail lamp 52 and the light emission due to reflection on the lower surface 64 of the rear grip 61 appear to be separated vertically.

  Further, the recess 66 also functions as a finger hook portion of the hand placed on the rear grip 61. That is, when the rear occupant grips the rear grip 61 with his hand on the rear grip 61, the fingertip is placed in the recess 66, and the gripability of the rear grip 61 is improved. It is further improved. The upper surface 63 of the rear grip 61 and the upper surface of the rear seat 35 are generally continuous, so that the luggage placed on the rear seat 35 and the rear grip 61 is easily stabilized.

  As described above, the vehicle body rear structure in the above embodiment is applied to the motorcycle 1 including the tail lamp 52 provided at the rear of the vehicle body and the rear grip 61 provided above the tail lamp 52. The rear grip 61 has a flat surface portion 65 that allows the lower surface 64 to be continuous. The flat surface portion 65 is provided with a reflective portion 65a that faces the tail lamp 52 and reflects light from the tail lamp 52 backward. is there.

  According to this configuration, the light reflected backward by the reflecting portion 65a above the tail lamp 52 plays the same role as the light distribution by the high-mount stop lamp, thereby further improving the visibility of the tail lamp 52. Thus, it is possible to reduce the cost of the rear part of the vehicle body by eliminating the need to provide a separate high-mount stop lamp.

  Further, in the rear structure of the vehicle body, a recess 66 that suppresses rearward reflection of light from the tail lamp 52 is provided in a portion of the rear grip 61 near the tail lamp 52, so that the rear lamp 61 is provided between the tail lamp 52 and the reflecting portion 65a. The recessed portion 66 is disposed, and the direct light from the tail lamp 52 and the reflected light from the reflecting portion 65a can be separated to further improve the visibility.

The present invention is not limited to the above-described embodiments. For example, the rear grip 61 may have a function as a rear carrier or may be integrated with the rear carrier. Further, as a means for suppressing the backward reflection of the bulb light from the upper lens 54a, it may be a convex part instead of the concave part 66, or the reflection itself may be suppressed by embossing, knurling or matting.
Then, that the configuration in the above embodiment is an example of the present invention, a three-wheeled or four-wheeled vehicle or can be also applied to a scooter type vehicle, of course, various modifications are possible without departing from the scope of the invention Needless to say.
