Claims (1)

[Scope of utility model registration request] slanted grooves that rise in the longitudinal direction of the vehicle; and slanted grooves that are arranged along the slanted grooves within the slanted grooves, and that are in a non-contact state with each other in a vicinity including the lowest point within the slanted grooves. A reed switch is sealed in the inclined groove, and when the acceleration/deceleration is high, the reed switch rises upward in the inclined groove due to inertia force, and de-energizes the reed switch. It has a plurality of G sensors for anti-skid control consisting of mercury bulbs that stop at the lower point and turn on the reed switch, and compares the output signals of the G sensors, and when the signals differ from each other, the The present invention is characterized by comprising a comparator that sends an on signal when one of the G sensors is in failure, and a failure notification means that notifies the failure of the G sensor when the on signal is received. Anti-skid G sensor failure alarm device.
