PURPOSE: To release an acceleration sensor surely and reliably by providing a specific inclinable component rotationally symmetric to the optical axis of the sensor. CONSTITUTION: The acceleration sensor 10 comprises an inclinable component 45 rotationally symmetric to the optical axis Z of the sensor. The component 45 is provided with a flange 48 projecting radially and the circumference fringe of flange 48 is spaced apart by a predetermined distance from a contact face A in the vertical direction and located at a fulcrum D. The component 45 is made of a ferromagnetic body. The component 45 performs a limited inclining motion 55 to a second operating position through means 30, 31 for holding the component 45 on the contact face A with a predetermined force FH in the direction of the optical axis Z when the component 45 is in a first operating position and guide means 27, 29, 31. When the component 45 is in the first operating position (stationary position), it is mounted on the holding means 30, i.e., a magnet 30 magnetized in the axial direction. |
