Claims

[Claims for Utility Model Registration] Movement constituted by a flat connecting part made of an elastic body and a pair of drive legs made of an elastic body protruding from both ends of the connecting part in a substantially vertical direction. and a piezoelectric vibrator or an electrostrictive vibrator that is fixed to the moving element and applies vibrations to both of the drive legs. a spring means having one end supported on the upper side of the housing and holding a biasing force for pressing the slider toward the rail; and a spring means having one end supported on the lower side of the housing and opposite to the slider. A support structure for a rail of an ultrasonic linear motor, characterized by comprising a bearing part that comes into contact with a side rail surface.
