By bending and positioning the knob part 42 bent inward from the corner part 31 formed on the side edge of the surface part 30 and holding it inside the cover member 45, the knob part at the terminal part of the skin body 14 is fixed. 42 slips into the inside of the cover member 45, and the end portion of the skin body 14 can be easily treated so as not to be exposed to the outside. Furthermore, even if there is variation in size in the knob 42 of the skin body 14, the variation is unlikely to be exposed to the outside, and a good appearance can be obtained.

In addition, when the cover member 45 and the component 35 are attached to the steering wheel main body 3 from the front and back, the component 35 is positioned with the end portion of the skin body 14 sandwiched between the surface portion 30. At a position P that is a boundary point between the arm portion 52, the component 35, and the end portion of the skin body 14, the cover member 45 and the component Covered by 35. Therefore, a good appearance can be obtained. In addition, there is no need to cut the end portion of the skin body 14 according to the shape of the cover member 45 and the component 35, for example, so as not to interfere with the cover member 45 and the component 35, and the number of man-hours can be reduced. Variations such as the end face of the terminal part being exposed to the outside are eliminated, and a stable shape is maintained, improving product precision.

Note that in the above embodiment, the end portion of the skin body 14 extending from the rim portion 6 side to the spoke portion 7 side may be covered from the front side by a module 10 that is a component instead of the component 35. .
