[0007]
According to the support structure for the light unit according to the above (1) of the present invention, it is possible to support the housing on the vehicle body cover by sandwiching it between the upper and lower sides, for example, when only the top and side portions of the housing are supported on the vehicle body cover. Compared to this, the vertical shaking of the light unit can be suppressed with a simple configuration. In particular, by supporting the housing from both sides in the vertical direction, it is possible to easily suppress the shaking of the light unit due to pitching when the vehicle accelerates or decelerates. Each engaging part on the housing side and each engaging part on the vehicle body cover side constitute a contact support structure that can be separated from each other, so compared to a support structure that uses fasteners etc., parts cost and installation/removal man-hours are reduced. can be suppressed.
Further, it is possible to easily suppress the vibration of the light unit not only in the vertical direction but also in the front-back direction. Moreover, by supporting the vertical direction and the front-back direction, it is possible to cope with sudden starting and braking of the vehicle.
In addition, it becomes possible for at least one of the upper side support structure and the lower side support structure and the front-back support structure to share each engagement part with each other, so that the structure is simplification and common use of parts.
In addition, in the support structure of the tail light unit at the rear of the vehicle body, the upper support structure and the rear support structure share an engaging part, and the lower support structure and the front support structure share an engaging part with each other. . That is, the upper side support structure and the front side support structure use mutually different engagement parts, and the lower side support structure and the rear side support structure use mutually different engagement parts. As a result, by essentially only providing two abutment support structures, the load can be distributed between these two abutment support structures, while shaking in the pitching direction (swinging diagonally forward and upward and diagonally backward and downward). can be suppressed efficiently.
Furthermore, the arrangement can be made suitable for a rear body cover that rises backwards. That is, it is preferable that the upper part of the rear body cover extends further rearward than the lower part around the tail light unit, and the lower support structure is located relatively toward the front of the vehicle.
