<p>An angle detection device capable of highly accurately detecting a rotational angle independent of displacement, play, and eccentricity of a drive shaft. The angle detection device has the drive shaft (4), a rotation sensor (5), and a rotating body (3) placed between the drive shaft (4) and a rotor (53) of the rotation sensor (5). The rotating body (3) has an elastic section (15) and a pivot shaft (16) and rotates about a rotation axis (L). The elastic section (15) has a through-hole (3b) at the center in a lateral cross-section of the elastic section and has a structure where solid sections (3c) that are perpendicular to each other are piled up on each other. The pivot shaft (16) is rotatably supported at a pivot shaft receiver (32) of a cover (2b) and is positioned on the rotation axis (L) by a bearing (58) by using the rotor (53).</p> |
