PROBLEM TO BE SOLVED: To provide a suction device that improves a supercharger effect by increasing a suction amount circulating in a fluid passage communicating two spaces in a surge tank in a case where a valve body is at an opened position, and can ensure excellent sealability in a case where the valve body is at a closed position.SOLUTION: A suction device 100 includes a suction device body 105 including a surge tank 1 for a V-shaped six-cylinder engine 10, and a valve body 21 for opening/closing a fluid passage 41 formed on a partition wall 4 dividing the inside of the surge tank 1 into two. The suction device body 105 is formed by connecting a middle piece 103 into which the valve body 21 is assembled with an upper piece 101 and a lower piece 102. The middle piece 103 is arranged in the vicinity of the fluid passage 41, and has a jig receiving part 161 and a jig receiving surface 4a for receiving jigs 201, 202 holding the middle piece 103 in connection between the middle piece 103 and the lower piece 102 and in connection between the middle piece 103 and the upper piece 101. |
