When a collision detecting mechanism 27 detects a front collision of a vehicle, a clutch mechanism 18 integrally connecting a pedal arm 2 to a push rod lever 15 connecting a push rod 14 of a Master vac 13 is disconnected. Accordingly, even when the push rod 14 is backward moved together with the Master vac 13, the push rod lever 14 strikes the air, so that a collision load does not act on the pedal arm 2. <IMAGE> |
