PROBLEM TO BE SOLVED: To solve the problem that a drive device is conventionally secured to a rotary valve by bolting, and bolting is troublesome, then to secure with a simple operation, in the extreme case, with a one-touch operation. SOLUTION: A securing projection standing upright from a mounting surface is installed in the mounting surface of the drive device facing toward a flange attached to the rotary valve. A cleavage cutting the projection from the front end into two places in the axial direction is installed in the securing projection, and a swelling section projecting in the perpendicular direction to the cleavage is installed in the front end of the securing projection. A through-hole is bored at the position corresponding to the securing projection in the flange surface. When the inside diameter of the through-hole is pressed against the front end of the securing projection toward the narrower direction of the cleavage, such a size that the swelling section can not pass the through-hole is made. When the pressing is stopped, a detent, a frame, etc., are annexed to the mounting surface. COPYRIGHT: (C)2006,JPO&NCIPI
