Claims

[Scope of utility model registration request]

A switch means is provided in parallel with the exhaust brake switch that turns on when the foot brake is stepped on when the gear position is not neutral, and when the clutch is connected to a first normally open relay that turns on when the gear position is neutral. An exhaust brake circuit characterized in that a second normally open relay that is energized via a clutch switch that is turned on is provided in series with a power supply circuit of a magnetic valve for idle up.
