制動解除装置。 A motor 5 is connected between the diagonals of a bridge circuit 4 in which a forward switch 1 and a reverse switch 2 are connected in parallel to a power source 3, and the motor 5 is rotated forward and reverse by connecting the forward switch 1 or the reverse switch 2. In an electric vehicle that moves the aircraft forward and backward, both switches 1 and 2 are provided with contacts on the common side a, make side b, and break side c, and the common side contacts a and a of both switches 1 and 2 are connected together. By connecting to the break side contacts c and c, the power to the power supply 3 is cut off and the motor 5
A brake release device for an electric vehicle is configured to form a closed circuit 6, and an on/off switch 7 is provided in the closed circuit 6.
