A sensor device includes a main driving gear (52), a driven gear (53, 54), a biasing member (85), a support member (55), a rotational angle sensor (62, 63), and a magnetic shield (75, 76). The drivengear includes a gear portion (71, 73) and a shaft portion (72, 74). The shaft portion is provided with a permanent magnet. The biasing member (85) is configured to bias the driven gear toward the maindriving gear. The support member supports the driven gear and the biasing member. The magnetic shield rotatably surrounds the shaft portion. The biasing member biases the driven gear toward the maindriving gear by biasing the magnetic shield toward the main driving gear. The sliding resistance between the magnetic shield and the driven gear is lower than the sliding resistance between the magnetic shield and the biasing member.

    本发明提供了一种传感器装置,其包括主驱动齿轮(52)、从动齿轮(53,54)、偏置构件(85)、支承构件(55)、旋转角度传感器(62,63)以及磁屏蔽件(75,76)。从动齿轮包括齿轮部分(71,73)和轴部(72,74)。轴部设置有永磁体。偏置构件(85)构造成将从动齿轮朝向主驱动齿轮偏置。支承构件支承从动齿轮和偏置构件。磁屏蔽件以可旋转的方式围绕轴部。偏置构件通过将磁屏蔽件朝向主驱动齿轮偏置来将从动齿轮朝向主驱动齿轮偏置。磁屏蔽件与从动齿轮之间的滑动阻力小于磁屏蔽件与偏置构件之间的滑动阻力。
