A stator(200) is arranged in the base(10) and includes a magnet(210) and yokes(120) fixing the magnet. A case includes a first case(300) and a second case(304) which is extend from the first case and is fixed in the base. A guide pin(420) is extended from the first case to the inside of guide groove which is formed in the upper part of a bobbin.
