The purpose of the present invention is to provide: a position detection device which can be reduced in size; and a vehicle steering device provided with the position detection device. A stroke sensor (2) detects the position of a rack shaft (12) in which a conductive portion (121) and a recessed portion (120) are disposed side by side in the movement direction. The stroke sensor (2) is provided with an excitation coil (31) and detection coils (32, 33) which are arranged so as to extend in the movement direction of the rack shaft (12), and a voltage is induced in the detection coils (32, 33) by a magnetic field generated by the excitation coil (31). The magnitude of the voltage induced by the detection coils (32, 33) changes in accordance with the position of the rack shaft (12) in the movement direction with respect to the detection coils (32, 33). A vehicle steering device (1) is provided with: a rack shaft (12); a housing (13) that contains the rack shaft (12) and is made of a conductive metal; and a stroke sensor (2) that detects the position of the rack shaft (12) with respect to the housing (13).

    目的在于提供能够小型化的位置检测装置和具备该位置检测装置的车辆用转向装置。行程传感器(2)检测沿移动方向并排设置有导电部(121)和凹部(120)的齿条轴(12)的位置。行程传感器(2)具备沿齿条轴(12)的移动方向延伸配置的励磁线圈(31)和检测线圈(32、33),因励磁线圈(31)产生的磁场而在检测线圈(32、33)感应出电压。在检测线圈(32、33)感应出的电压大小根据齿条轴(12)相对于检测线圈(32、33)在移动方向的位置而变化。车辆用转向装置(1)具备齿条轴(12)、收纳齿条轴(12)的由导电性金属构成的壳体(13)、和检测齿条轴(12)相对于壳体(13)的位置的行程传感器(2)。
