ROTATION ANGLE DETECTING DEVICE |
| 摘要 |
A rotation angle detecting device includes: a magnet member placed in a shaft member to face a magneto-electric conversion element and detecting a rotation angle of the shaft member in response to a relative rotation of the magnet member with respect to the magneto-electric conversion element, wherein the magnet member has a magnet where a groove formed in a rectangular parallelepiped body having maximum surfaces orthogonal to an axis of the shaft member is formed to be open to one maximum surface side of the rectangular parallelepiped body and extend in parallel to a short-side lateral surface of the rectangular parallelepiped body, and is magnetized along the groove with respect to the magnet. |

1. A rotation angle detecting device comprising:
a magnet member placed in a shaft member to face a magneto-electric conversion element and detecting a rotation angle of the shaft member in response to a relative rotation of the magnet member with respect to the magneto-electric conversion element, wherein the magnet member has a magnet where a groove formed in a rectangular parallelepiped body having maximum surfaces orthogonal to an axis of the shaft member is formed to be open to one maximum surface side of the rectangular parallelepiped body and extend in parallel to a short-side lateral surface of the rectangular parallelepiped body, and is magnetized along the groove with respect to the magnet. |
