<P>PROBLEM TO BE SOLVED: To improve operational reliability of a link mechanism with interference between a slider and a guide part avoided by slanting a guide direction of the slider by the guide part toward the side disposed with a spindle. Ž<P>SOLUTION: A lock device 2 includes: a connection plate 21 with the center part in a longitudinal direction secured on a rotation shaft 2a1; a lever fitting 22 in which one end is axially supported on the end of the connection plate 21 by a screw 2B; a lever 23 in which one end is axially supported on the end of the lever fitting 22 by a screw 2C and another end side is supported by a guide base 24 from the bottom side; and a guide cover 25 secured on the guide base 24. A guide recess part 25a of the guide cover 25 is disposed with the axis C0 intersecting with the shaft center of the rotation shaft 2a1 and the axis C1 of the guide recess part 25a slanted to the axis C0. When the connection plate 21 is rotated with the rotation shaft 2a1, the lever fitting 22 is rotated in an opposite direction (counterclockwise rotation) to the connection plate 21 about the screw 2B to extrude the lever 23 to the guide base 24 side. The lever 23 is moved in an extrusion direction by the lever fitting 22 in the guide recess part 25a. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
