PROBLEM TO BE SOLVED: To improve workability during assembly of a driving means, in a link mechanism to rotate a member 4 to be driven between a first position and a second position by transmitting rotational movement of an output shaft 81 of the driving means 8 to the member 4 to be driven. SOLUTION: A holding groove part 512 to hold an intermediate link member 6 in a given position when the member 4 to be driven is positioned in a first position G is formed in a drive guide groove 51 with which an intermediate pin 62 situated at an intermediate link member 6 makes contact. This constitution, since the intermediate link member 6 is held in a given position even when a worker does not hold the link member as usual, facilitates registration between a screw through hole 83 and the screw threaded hole and improves screw fastening workability when the driving means 8 and a drive link member 7 are assembled to a case 1.
