PURPOSE:To obtain an angle detector of high accuracy and a low cost by fixing a common stand supporting two detection mechanisms to one point on a stand rotating around a main shaft. CONSTITUTION:When an antenna device rotates in an angle detector of an antenna device, a stand 4 rotates around a main shaft 6 under elastic deformation by external force. However, two detection mechanisms 2 are provided on a common stand 3 mounted at one point of the stand 4 and therefore the relative displacements of the two mechanisms 2 owing to the elastic deformation of the stand 4 are eliminated and no influences are given upon angle detection errors. Thereby, the angle detector of high accuracy and a low cost is obtained. |
