ABSTRACT:
An idle adjusting device for an engine having an air intake passage and a throttle valve disposed in the air intake passage, includes an auxiliary passage communicating with the air intake passage in such a manner as to bypass the throttle valve. A first member protrudes into the auxiliary passage so as to locally reduce the cross-sectional area of the auxiliary passage. A second member movably protrudes into the auxiliary passage at a position relatively near the first member so that the first and second members will cooperate to adjust the effective cross-sectional area of the auxiliary passage in accordance with movement of the second member.
