VEHICLE BODY SIDE STRUCTURE

The invention provides a vehicle body side structure using a turn light of a vehicle as welcome lighting. A vehicle body side structure (10L) is provided with: a turn light (1) that serves as a light source for irradiating an area in the turning direction when a vehicle (100) turns; a light path section (2) that constitutes a path through which light passes from the turn light (1) toward an area in the turning direction; and a reflection part (3) that is provided in the light passage part (2) and that reflects at least a part of the light so as to irradiate a region near the door opening in the side part of the vehicle body. 本发明提供将车辆具备的转向灯作为欢迎照明使用的车身侧部构造。车身侧部构造(10L)包括：转向灯(1)，其作为车辆(100)转弯时照射转弯方向的区域的光源；光通路部(2)，其构成光从转向灯(1)朝向转弯方向的区域通过的通路；以及反射部(3)，其设置于光通路部(2)，反射光的至少一部分以照射车身侧部的开门口附近区域。
