The elastic support part 6 elastically supports the acceleration sensor unit 5. The elastic support part 6 includes a support pin 61 and an elastic member 62. The support pin 61 is formed separately from the housing 10 and coupled to the housing 10. The elastic member 62 is disposed between the support pin 61 and the acceleration sensor unit 5 in at least an anteroposterior direction.SELECTED DRAWING: Figure 2
