PROBLEM TO BE SOLVED: To provide a steering wheel in which an entire perimeter of the steering wheel can be heated quickly.SOLUTION: A leather and a decorative member are provided on a surface part of a rim part of a steering wheel. A first heater part 24 for adjusting the temperature of the leather and a second heater part 32 for adjusting the temperature of the decorative member are controlled by an ECU 16. The ECU 16 starts energization only to the first heater part 24 first. When the temperature of the first heater part 24 reaches a targeted first specified temperature, the ECU 16 stops the energization to the first heater part 24 and then starts energization to the second heater part 32. When the temperature of the first heater part 24 becomes lower than a second specified temperature, the ECU restarts the energization to the first heater part 24 and thereafter controls ON/OFF of the energization to the first heater part 24 and the second heater part 32 so that the temperature of the first heater part 24 is kept between the first specified temperature and the second specified temperature.SELECTED DRAWING: Figure 4
【課題】ステアリングホイールの全周をすばやく暖めることのできるステアリングホイールを提供すること【解決手段】ステアリングホイールのリム部の表面部には皮革と加飾部材が設けられている。皮革の温度を調節する第1ヒータ部24と加飾部材の温度を調節する第2ヒータ部はECUによって制御されるように構成されている。ECU16は始め第1ヒータ部24にのみ通電を開始し、第1ヒータ部24の温度が目標とする第1規定温度に達するとECU16は第1ヒータ部24への通電を停止し、第2ヒータ部32への通電を開始する。第1ヒータ部24の温度が第2規定温度より下がると第1ヒータ部24への通電を再開し、以降は第1ヒータ部24の温度が第1規定温度と第2規定温度の間で保持し続けるように第1ヒータ部24と第2ヒータ部32への通電のON、OFFを制御する。【選択図】図4
