摘要： There is provided a driving control device of an opening and closing body, which drives the opening and closing body in a closed state by a motor through an idling section thereof. The device includes a calculation section for calculating a rotation speed difference between a rotation speed of the motor in the idling section and a current rotation speed of the motor; and an insertion detection section for detecting insertion of a foreign member based on the calculated rotation speed difference and a predetermined threshold value. The threshold value monotonously decreases according to an increase in the rotation amount of the motor to coincide with a fully-closed state threshold value at a predetermined rotation amount of the motor within an error range of the rotation amount corresponding to the fully-closed state, and to maintain the fully-closed state threshold value to a maximum rotation amount in the error range.

摘要： When a worm wheel rotates relative to an object pinching detection plate due to pinching of a foreign object, protruding pieces respectively formed on opposed surfaces of the worm wheel and the object pinching detection plate engage with each other. Through the engagement, the object pinching detection plate axially moves. At this time, the object pinching detection plate axially moves without rotation, and hence the object pinching detection plate is brought into contact with a movable piece of an object pinching detection switch without rotation. Therefore, wear due to rotation does not occur when the object pinching detection plate and the object pinching detection switch are brought into contact with each other. Thus, deterioration in object pinching detection accuracy due to the wear is prevented.
