When an external detection device detects an obstacle (another vehicle (T)) on either a left or right side of the own vehicle (M), a control device of a steering assistance device for a saddle type vehicle controls an assist torque so that a handle operation to the side opposite to the side on which the obstacle is detected becomes heavier (more difficult to turn) than a case in which the obstacle is not detected. The handle operation to the side on which the obstacle is detected makes a handle relatively light (makes it easier to turn) while steering assist is maintained.
