PROBLEM TO BE SOLVED: To prevent a wiring structure from being complicated and prevent cost required for a configuration from increasing while realizing warming of a steering wheel and acquisition of a heartbeat signal.SOLUTION: A vehicular steering device 10 comprises a low-resistance electrode part 11, a high-resistance electrode part 12, a harness 13, an electrification part 31, a heartbeat detection part 32, and a control part 16. The low-resistance electrode part 11 is provided on a steering wheel of a vehicle. The high-resistance electrode part 12 is provided on an outer surface of the low-resistance electrode part 11. The electrification part 31 is connected to the low-resistance electrode part 11 and the high-resistance electrode part 12 by one harness 13. When the control part 16 electrifies from the electrification part 31 to the low-resistance electrode part 11 and the high-resistance electrode part 12, at least the low-resistance electrode part 11 generates heat. When the control part 16 does not electrify from the electrification part 31 to the low-resistance electrode part 11 and the high-resistance electrode part 12, the heartbeat detection part 32 detects heartbeat of a driver based on a signal pattern obtained from the high-resistance electrode part 12.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】ステアリングホイールの加温および心拍信号の取得を実現しつつ、配線構造が複雑になることを防ぎ、構成に要する費用が嵩むことを防ぐ。【解決手段】車両用ステアリング装置10は、低抵抗電極部11と、高抵抗電極部12と、ハーネス13と、通電部31と、心拍検出部32と、制御部16と、を備える。低抵抗電極部11は、車両のステアリングホイールに設けられる。高抵抗電極部12は、低抵抗電極部11の外面に設けられる。通電部31は、1つのハーネス13によって低抵抗電極部11および高抵抗電極部12に接続される。制御部16が通電部31から低抵抗電極部11および高抵抗電極部12へ通電する場合に、少なくとも低抵抗電極部11は発熱する。制御部16が通電部31から低抵抗電極部11および高抵抗電極部12へ通電しない場合に、心拍検出部32は高抵抗電極部12から得られる信号パターンに基づいて運転者の心拍を検出する。【選択図】図1
