VIBRATION-RESISTANT ACTUATOR, AND ACTIVE TYPE VIBRATION-RESISTANT DEVICE WITH THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a vibration-resistant actuator with a new structure capable of easily opening and closing an opening of a guide hole guiding a guide rod in a simple structure and blocking it with an advanced sealing property. SOLUTION: A cover plate metallic fixture 148 is fitted on the opening of the guide hole 142 being as a large diameter section 143, and a C-shaped stop ring 155 is locked on an inner peripheral surface of the large diameter section 143 so as to block slipping out of the opening of the cover plate metallic fixture 148. The cover plate metallic fixture 148 is pressed by the C-shaped stop ring 155 after a seal rubber layer 154 is formed and stuck on the inside of the cover plate metallic fixture 148, and the opening of the guide hole 142 is sealed by pushing the seal rubber layer 154 onto the opening.
