In other words, the front surface 52a of the lens 52 has a partial columnar shape, and the shape of the outer side 56b of the base portion 56 is a flat surface that forms a straight line along the extension line of the handle 39 in a top view. The shape of the lens 52 is set so as to have a continuous surface shape with no step difference from the lamp case 51. Thereby, when the driver grips the grip 40, it is possible to prevent the front winker 44 from being caught by a finger or a hand, so that the operability of the handle can be improved. Further, since the front winker 44 is tapered and the outer shapes of the grip 40 and the front winker 44 are different, the driver can clearly distinguish the grip 40 and the front winker 44 by touch.

  Further, since the lamp case 51 has a linear portion (base portion 56), when the front winker 44 is attached to the handle 39, the front winker 44 is easily grasped and attached (screwed) to the handle 39. The same applies to the removal.

  In the above-described embodiment, the configuration and effects of the front winker 44 on the left side of the vehicle body are particularly described in detail. However, the present invention is not limited to the left front winker 44 and is similarly applied to the right front winker 44. can do. Further, the lamp case 51 does not screw and fix the coupling portion 51c to the handle 39, but screw the set screw from the outer periphery of the handle 39 toward the coupling portion 51c to connect the handle 39 and the lamp case 51.
