A driving device for a door opener includes a motor driving a first transmission member to rotate. Rotation of the first transmission member causes lateral displacement of a sliding member which moves jointly with a connecting rod. A return spring is mounted around the connecting rod. An adjusting ring is in threading connection with the connecting rod and abuts against the return spring. When the first transmission member does not rotate, rotation of the adjusting ring causes displacement of the adjusting ring in the lateral direction to change an extent of pre-compression of the return spring. When the first transmission member rotates in a direction, the connecting rod and the adjusting ring together move in the lateral direction towards the first transmission member, and the return spring is compressed. When the first transmission member rotates in a reverse direction, and the return spring restores its length.
