Title: STEERING WHEEL AND METHOD FOR MANUFACTURING SAME
Abstract:
Provided are: a steering wheel configured such that a sensor is mounted on the steering wheel, the surface hardness of the steering wheel is maintained, and the steering wheel is excellently designed; and a method for manufacturing the steering wheel. This steering wheel 1 has a steering hub 7, a wheel 2, and spokes 8L, 8R, 8D extending from the steering hub 7 and continuous with the wheel 2. The wheel 2 is provided with: a metallic core 3 extending circumferentially along the steering wheel; a foamed synthetic resin layer 4 covering the metallic core 3; a sensor 10 covering the foamed synthetic resin layer 4; and leather 5 directly covering the sensor 10 and forming the outermost surface of the wheel 2. The sensor 10 has a circular arc shape or an annular shape extending in the circumferential direction of the steering wheel and is composed of a plurality of sensors having a U-shaped or C-shaped cross-sectional shape. The outer surfaces of the sensors are continuous without steps.
