Steering system

Abstract

To provide a steering device equipped with a first light emitting part that can increase a ratio of light that shines on a gripping part.SOLUTION: The steering device comprises a rotating part that is rotatably mounted on a moving body and a gripping part connected to the rotating part and symmetrically constituted across the rotating part. The rotating part comprises a light emitting part that emits light toward at least a portion of the gripping part, and the light emitting part comprises a light emitting element that emits light in a predetermined angle range and a lens that narrows the angle range of the light emitted by the light emitting element. When a direction in which at least a portion to which light is emitted of the gripping part extends is defined as a first direction, a direction perpendicular to a direction of a light axis of the light emitted by the light emitting part and the first direction is defined as a second direction, a surface including the light axis and the first direction is defined as a first surface, and a surface including the light axis and the second direction is defined as a second surface, the lens narrows the angle range of the light emitted by the light emitting element so that a first angle range which is an angle range in the first surface becomes larger than a second angle range which is an angle range in the second surface.SELECTED DRAWING: Figure 3

Claims
