A lane departure suppression device is provided in a car equipped with a steering angle change mechanism that changes a steering angle and with a motor that operates the steering angle change mechanism, and the lane departure suppression device includes: a main control unit that outputs a main control signal after a position of the car reaches a deflection starting position at which deflection of the car is started in order to suppress departure of the car from a lane, the main control signal representing a main control amount for causing the motor to generate an assist torque that changes the steering angle; and a pre-control unit that outputs, until the main control unit outputs the main control signal, a pre-control signal while the position of the car is located closer to a center of the lane than the deflection starting position is, the pre-control signal representing a pre-control amount for causing the motor to generate an assist torque equal to or less than a friction torque of the steering angle change mechanism.
