Claims

[Scope of utility model registration request]

A switch means that is turned on when the foot brake is stepped on when the gear position is not neutral is provided in parallel with the exhaust brake switch, and a switch means that is turned off when the gear position is not neutral and the clutch is engaged is provided for idle up. An exhaust brake circuit characterized by being installed in series with the magnetic valve's power supply circuit.
