<P>PROBLEM TO BE SOLVED: To provide an acceleration sensor improved in durability by preventing break of a stopper part. <P>SOLUTION: When downward vibration is applied to a weight member 36 and the weight member 36 is displaced downward, the bottom of the weight member 36 hits a bottom plate 90 and the weight member 36 stops, which prevents downward displacement. When the weight member 36 is displaced upward, an edge part 36B of the weight member hits a stopper part 20 and the weight member 36 stops, which prevents upward displacement. If the strength of the stopper part 20 is low, a break of the stopper part 20 may occur because displacement of the weight member 36 is prevented by hitting the stopper part 20. However, this sensor is provided with reinforcement parts 24 to reinforce the stopper part 20 on both sides thereof, which prevent the break of the stopper part 20, and thereby improves durability of an acceleration sensor 100. <P>COPYRIGHT: (C)2009,JPO&INPIT |
