To provide a door holding force generator capable of holding a door open at a predetermined opening further securely.SOLUTION: A door check device 20 comprises a housing 30, a cylinder member 31, a piston member 32, a rod member 33, an electromagnetic coil 34, a first flow passage 35, a second flow passage 36, a check valve 37 and an electromagnetic valve 38. The first flow passage 35 and the second flow passage 36 connect a first space S1 and a second space S2. The check valve 37 restricts a magnetic fluid F of the first space S1 from flowing into the second space S2 through the first flow passage 35 in response to an opening action of a swing door while allowing the magnetic fluid F of the second space S2 to flow into the first space S1 through the first flow passage 35 in response to a closing action of the swing door. A door ECU 21 has the electromagnetic valve 38 in an open state until an opening angle of the swing door reaches a limit angle and has the electromagnetic valve 38 in a closed state when the opening angle of the swing door reaches the limit angle.SELECTED DRAWING: Figure 3

    【課題】所定の開度で開いているドアをより確実に保持できるドア保持力発生装置を提供する。【解決手段】ドアチェック装置20は、ハウジング30、シリンダ部材31、ピストン部材32、ロッド部材33、電磁コイル34、第1流路35、第2流路36、逆止弁37、および電磁弁38を備えている。第1流路35および第2流路36は、第1空間S1と第2空間S2とを接続している。逆止弁37は、スイングドアの閉動作に対応して第2空間S2の磁性流体Fが第1流路35を介して第1空間S1へ流動することは許容しつつ、スイングドアの開動作に対応して第1空間S1の磁性流体Fが第1流路35を介して第2空間S2へ流動することは規制している。ドアECU21は、スイングドアの開角度が制限角度となるまでは、電磁弁38を開状態とし、スイングドアの開角度が制限角度に達したときには、電磁弁38を閉状態とする。【選択図】図3
