Claims

[Scope of utility model registration request]

In an impact sensing device, a sensing mass moves in response to acceleration when an impact is applied, and closes a contact point when the sensing mass moves a predetermined distance. An impact sensing device characterized in that the spherical body suppresses movement of the sensing mass when an impact is applied.
