On a steering wheel unit, a sensitive region for detecting contact of a human body with respect to a steering wheel is formed by arranging an electrostatic capacitance sensor on an outer circumferential portion of a rim of the steering wheel, and non-sensitive regions that do not detect contact of the human body with respect to the steering wheel are formed, respectively, on a left portion (left spoke connected part) positioned relatively to the left on the rim, and on a right portion (right spoke connected part) positioned in facing relation to the left portion via a center portion of the rim when the steering wheel is in a neutral state.
