<p>A throttle assembly (30) including a bore wall (40) to which a seal member (60) is previously attached is inserted into a key-like slot (21) of an intake air passage body (20), and flanges (25, 35) are fixed to each other by screws (65). A bore inner wall (45) of the bore wall (40) is placed to correspond to an inner wall of an intake air passage (11), and the seal member (60) completely seals between the intake air passage body (20) and the throttle assembly (30). That is, the throttle assembly (30) including the seal member (60) is inserted into the key-like slot (21), so that the throttle assembly (30) is easily attached to the intake air passage body (20), a sealing mechanism therebetween is simplified, and a stress strain of the bore wall (40) is prevented. <IMAGE></p> |
