PURPOSE:To provide a shock sensor capable of sensing shocks from many directions and having no anxiety of damaging a magnet and no limitation on the fitting direction. CONSTITUTION:A magnet 15 having the preset void between it and a reed switch 12 stored in a main body casing 11 is fixed and arranged, and a nearly fan-shaped magnetic shielding plate 16 is rotatably arranged in the void between the reed switch 12 and the magnet 15 while the vicinity of its curvature center serves as a fulcrum. The magnetic shielding plate 16 is normally held by springs 18a, 18b at the position magnetically shielding the contact section 12a of the reed switch 12 from the magnet 15. |
