<p><P>PROBLEM TO BE SOLVED: To reduce assembly man-hour and cost, and improve productivity by equalizing side clearance of both sides in a rotary shaft direction of multiple intake air flow control valves 2 without putting a shim therebetween. <P>SOLUTION: In a multiple series integrated valve open close device, projection parts 71, 72 for retaining and fixing the intake air flow control valve 2 under a condition where the same touches a valve left and a valve right side surfaces of the intake air flow control valve 2 and grips the intake air flow control valve 2 are provided on each of a plurality of housings 6 built in an inside of an intake manifold 1. Each projection part 71, 72 projects out of each side wall surface of housing left and housing right wall parts by height enabling rough equalization of side clearance of both sides formed between each side wall surface of the housing left and the housing right wall part of the housing 6 and the valve left and the valve right side surface of the intake air flow control valve 2. Consequently, productivity is improved since labor of building in and taking out the shim to/from the both sides of the plurality of intake air flow control valves 2. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
