Abstract
First and second guide means are provided to both a movable member which moves together with a vibration member, which is in press contact with a rail-shaped stator, and the rail-shaped stator. The first and second guide means have different functions: the first guide means restricts the degree of freedom of the movable member, and the second guide means receives a total compression counterforce of the vibration member.
