A brake device S has a switching unit 6 having: a first pipe 7 one end of which is connected to a brake pedal B and through which air supplied from a main air tank 4 passes; a second pipe 8 one end of which is connected to the brake pedal B, through which the air is passed, and which is longer than the first pipe 7; a first partition plate 67 that partitions a first space 651 into which air flows from the first pipe 7 and a second space 652 into which air flows from the second pipe 8; and a valve 62 that opens and closes a second opening 69 that allows air flowing in from a wheel park air tank 5 to flow out to a service line 1. When the brake pedal B is stepped on: air flows in from the first pipe 7 into the first space 651, the first partition plate 67 moves, and as result, the valve 62 moves; and the valve 62 moves further as a result of air flowing in from the second pipe 8 thereby closing the second opening section 69.
