SUPPORT MECHANISMS AND TIGHTENING STRUCTURES FOR VIBRATION ACTUATOR

摘要

PURPOSE: A support machine of a vibration actuator and a coupling structure thereof are provided to support a vibration actuator by fixing a stator of a vibration actuator by a narrow member, thereby preventing influences to vibration of the vibration actuator. CONSTITUTION: A vibrator(1013) is placed between a base block(1011) and a stator(1012). A recess part(1015) is formed on the other side of the stator opposite to the side of the stator contacting the vibrator. A support member(1017) is arranged on the stator. A ring shaped part(1018) and an angle part(1019) are fixed onto the stator. A pre-pressurizing unit(1020) is formed on the leading end of the angle part.
