<P>PROBLEM TO BE SOLVED: To surely hold the connection of a turning shaft and a guide vane by a simple constitution. <P>SOLUTION: This drive mechanism of a variable guide vane is constituted so that a guide vane unit 2 is fit to a step 10 of a housing 3 having the step 10 at an suction port 7 of a compressor impeller, the guide vane unit 2 sandwiches and supports a shaft 22 of the guide vane 1 so as to be turnable between a bearing ring 14 and a presser ring 15 which are divided by opposing faces, and the drive mechanism has a turning shaft 29 connected to the shaft 22 of one guide vane 1 of the guide vane unit 2 fit to the step 10 through a penetration hole 28 formed at the housing 3. The mechanism also comprises a snap ring 40 which is attached to the internal end 29' of the turning shaft 29 which protrudes to the inside of the step 10 of the housing 3 from the penetration hole 28 and is connected to the shaft 22 of the guide vane 1, and regulates the movement of the turing shaft 29 to the outside. <P>COPYRIGHT: (C)2013,JPO&INPIT |
