A magnetic sensor unit capable of accurately detecting a change in a magnetic field by a magnetic sensor and accurately positioning a position of each magnet relative to a yoke. The magnetic sensor unit includes a yoke fixed to the rotor relatively displaced with respect to the substrate, two magnets fixed to the yoke and disposed apart from each other in a relative displacement direction of the rotor, and a magnetic sensor fixed to the substrate and detecting a change in a magnetic field formed by the two magnets. The yoke has a convex portion protruding between the two magnets. The convex portion includes an abutting portion on which the two magnets abut.

    一种磁性传感器单元,其能够通过磁性传感器准确检测磁场的变化,并准确定位每个磁体相对于磁轭的位置。磁性传感器单元包括:固定到相对于基板相对位移的转子的磁轭、固定到磁轭并在转子的相对位移方向上彼此分开设置的两个磁体、以及固定到基板并检测由两个磁体形成的磁场的变化的磁性传感器。磁轭具有在两个磁体之间突出的凸部分。凸部分包括两个磁体抵接在其上的抵接部分。
