TURN INDICATOR DEVICE OF SADDLE-RIDING TYPE VEHICLE

PROBLEM TO BE SOLVED: To provide a lamp body case which is capable of protecting a turn indicator device using an LED (Light Emitting Diode) and provided on a handlebar grip end from the external force, and efficiently radiating the heat generated in the LED or a driving circuit, and functioned as a dynamic damper.SOLUTION: A lamp body case 51 accommodates them therein an LED 53 as a light source and a driving circuit 54 of the LED 53 mounted on a substrate 55. An opening part 51a of the lamp body case 51 is covered by a lens 52. The lamp body case 51 is screwed in an end of a handlebar 39, and mounted thereon. The lamp case 51 is formed of a metallic material as a thermal conductor, and includes a base part 56 having a mounting surface 56a with the substrate 55 being abutted thereon, and a case end part located on the outer side in the width direction of the vehicle body with respect to the base part 56. The lamp body case 51 has a profile to be tapered toward the outer side in the vehicle width direction.
