  "textContent": "The steering wheel includes a light source, a light guide member having a light passage portion that includes a first emission surface formed at an end of the light passage portion, guiding light output from the light source by the light passage portion, and emitting the light from the first emission surface, a transmission suppression portion suppressing a transmission of the light and covering a side surface of the light passage portion, and a lens member having transmissivity for emitted light emitted from the first emission surface, receiving the emitted light and having a second emission surface for emitting the emitted light outward. In a radial cross-section of the steering wheel, a position of the first emission surface in an optical axis direction of the emitted light is farther from an intersection point of the second emission surface and the optical axis than a position in the optical axis direction of an end on a lens member side of the transmission suppression portion.",
