ベース回路。[Claims for Utility Model Registration] A pair of forward/reverse control transistors is formed into a transistor bridge, a field winding of a DC motor is connected to the bridge, and the field winding is controlled by turning on/off the transistors. In a DC motor drive circuit that drives and controls a motor in forward or reverse rotation by changing the direction of current flowing through the circuit, a constant current is stably output to the base terminal of the forward/reverse control transistor in response to an ON signal of the transistor. A transistor-based circuit in a DC motor drive circuit, characterized in that a constant current circuit is connected to the transistor base circuit.
