<p>PURPOSE:To simplify conduction to the inside from an external circuit while holding the airtightness of an actuator, which inside must be made in an airtight condition, in a device that conducts electricity to the inside from the outside of the actuator. CONSTITUTION:A seal bush 49 is pressure attached to an opening portion of a housing 11 near a post 17 after passing lead wires through the holes 49a, 49b, 49c, and the inside and outside of the housing 11 are held in an airtight condition. A seal block 50 is fitted to the projected portion 49a of the seal bush 49 while guiding lead wires to the grooves 50a, 50b, 50c and pressure contacting the block 50 with a yoke 18. Thus, the lead wires cannot be drawn out even if the wires are pulled. Conduction to the inside from an external circuit can be simplified while holding the airtightness of this actuator by inserting the seal block and the seal bush into holes for communicating the inside and outside of the actuator as mentioned above.</p> |
