<p>PROBLEM TO BE SOLVED: To integrate the bottom wall of a stationary case for reducing the number of part items by shielding an opening in the peripheral wall of the stationary case with a cover, and continuing the cover to the peripheral wall as the same curvature. SOLUTION: A cylindrical peripheral wall 11b is made to protrude upward from the outer periphery of a bottom wall 11a of a fixed case 11. An opening 13 in the peripheral wall 11b is formed with a cover 14, and the cover 14 is formed into an arc shape, consisting of the same curvature as that of the peripheral wall 11b. One end in the peripheral direction is formed with a latching part 14a extending in the peripheral direction, after being reflected inward. The latching part 14a is fitted into the interior part of the peripheral wall 11b from one end of the opening 13 in the peripheral direction of the opening 13. Under this condition, the cover 14 is fitted into the opening 13 as a diameter having the same curvature as that of the peripheral wall 11b to form part of the peripheral wall 11b. A locking claw 14b is provided to the top end of the cover 14, and locking connection is provided for a locking groove 15a in a connector 15 so as to become continuous.</p> |
