PROBLEM TO BE SOLVED: To prevent recirculating gas from being led to reversely flow in an intake pipe, and also prevent deposits from being stuck to the circumference of a throttle valve. SOLUTION: In this device, in the following flow area of an intake air flow on the downstream side of the throttle valve 3 of an intake pipe 5, a curved pipe 24 opened toward the downstream side is made to server as a recirculating gas guide passage 17, thereby the terminal part of a recirculating gas introducing passage 8 can be formed. A recirculating gas control valve 4 is arranged on the way to the recirculating gas introducing passage 8. Recirculating gas flows assuredly to the downstream side by being carried on an intake following flow, thereby it may not be reversely led to flow toward the throttle valve 3. The recirculating gas guide passage 17 may be formed, for example, as a part comprising a partitioning wall and a slant surface. The thusly arranged recirculating gas guide passage 17 is arranged in this device, thereby not only sticking of deposits can be prevented, but also recirculating gas can be uniformly distributed to each air cylinder.

PURPOSE:To miniaturize the titled mechanism, and to let it have a multi- function, by constituting the mechanism so that when a dust guard door switch is turned ON in a state that a tape pack exists in a recording/reproducing position, an eject motor is driven until an eject completion switch is turned ON, and the tape pack is ejected. CONSTITUTION:At the inside of a tape pack insertion port 11 provided on an escutcheon 10, the dust guard door 12 provided with a projection 12a on the front, and an interlocking arm 13 are supported pivotally in a movable state. Also, at the inside of the excutcheon 10, a dust guard door switch 2 is fixed in the vicinity of the tip of the interlocking arm 13. When the dust guard door 12 is pressed, the interlocking arm 13 turns ON the dust guard door switch 2 by following up turning of the dust guard door 12. When the dust guard door switch 2 is turned ON in a state that a tape pack exists in a recording/reproducing position, an eject motor 7 is driven until an eject completion switch 8 is turned ON by the output of an AND circuit 3, and the tape pack is ejected. In such a way, the titled mechanism can be miniaturized and allowed to have the multi-function.
