ROTARY ANGLE AND ROTARY TORQUE SENSING DEVICE

A rotary angle and rotary torque device includes a rotary torque sensor for sensing rotary torque of a steering shaft, a first magnet, a first magnetism sensing element, a sensing gear engaged with a rotary gear, a second magnet mounted to the sensing gear, a second magnetism sensing element, and a controller. The rotary torque sensor includes a first rotator and a second rotator either one of which has the rotary gear. The first rotator rigidly adheres to the second rotator via a coupler. The first magnet is mounted to either one of the first rotator or the second rotator. The first magnetism sensing element faces the first magnet, and the second magnetism sensing element faces the second magnet. The controller senses a rotary angle based on signals supplied from the first and the second magnetism sensing elements.
