The first transmission mechanism of the present invention includes a first permanent magnet, a first rocking member with a rod-like shape that includes one end at which the first permanent magnet is disposed and is extended in Z-axis direction, and two supporting bodies that rockably support the first rocking member at two different positions in Z-axis direction of the first rocking member. The first rocking member is rocked to move the first permanent magnet by an amount of displacement smaller than an amount of displacement inputted to the first supporting body, which is located on a side of the other end of the first rocking member in the two supporting bodies.

A rotation angle detection device includes a rotary body rotating in linked motion with a steering wheel; a detector rotating in linked motion with the rotary body; a magnetic detection element placed on a wiring board and detecting magnetism of a magnet placed at the detector; a control part for detecting a rotation angle of the rotary body based on a detection signal from the magnetic detection element; and a holder latched onto the wiring board and rotatably holding the detector.

Rotation angle detection device

A rotation angle detector is provided with a spring to thrust a rotary body against protrusions formed on an inner wall of an opening via a detector body in a manner to keep the rotary body rotatable without any play in a linked motion with a steering shaft. As a result, the detector can detect rotation angles of the steering shaft with high accuracy.
