An input device includes: a rotating member that rotates about a predetermined rotation axis; and a mover that includes a protrusion protruding toward an inner peripheral surface of the rotating member and moves in a direction different from a rotation direction of the rotating member along with rotation of the rotating member. The protrusion protrudes toward an inner peripheral surface of the rotating member. The rotating member includes a first projection and a second projection that project from the inner peripheral surface toward the mover. The protrusion of the mover is inclined with respect to the predetermined rotation axis and disposed between the first projection and the second projection.

Input device

A rotational angle detection device includes a first gear that rotates about a first rotation axis and that has a main surface having an annular shape that crosses the first rotation axis and a plurality of first teeth provided on the main surface; a second gear that rotates about a second rotation axis in engagement with the first gear and that has a larger number of second teeth than the first teeth; and a sensor that detects a rotational angle of the second gear. The second rotation axis extends in a direction orthogonal to both of a virtual line that connects a center of the first gear and a position where the first gear and the second gear are engaged with each other, and the first rotation axis. Each of the first teeth extends so as to shift from an outer side toward an inner side in a radial direction of the main surface as it shifts along a circumferential direction of the main surface. Adjacent two of the first teeth are disposed so as to overlap each other in the radial direction.

Rotational angle detection device

A rotation angle detector includes a rotator, first and second detecting bodies, an auxiliary detecting body, first and second detectors, an auxiliary detector, and a controller. The first detecting body rotates in association with the rotator, and the first detector detects rotation of the first detecting body. The second detecting body rotates in association with the first detecting body at a different speed therefrom, and the second detector detects rotation of the second detecting body. The auxiliary detecting body is engaged with the rotator at a position symmetrical to the first detecting body with respect to a rotation axis of the rotator. The auxiliary detector detects rotation of the auxiliary detecting body. The controller detects a rotation angle of the rotator based on detection signals from the first, second, and auxiliary detectors.
