PROBLEM TO BE SOLVED: To provide a high-quality table device capable of being smoothly restrained by a movement restraint mechanism.SOLUTION: A stopper mechanism 50 capable of performing restraint and cancellation of the restraint of movement of a table device includes: a grounding member 51 capable of being projected from a caster 25 downward and contacting a floor face F; an arm member 55 including one end side 55a supported rotatably around a horizontal rotation shaft 56, and the other end side 55b being oscillated vertically by operation with an operation lever, with the rotation shaft 56 as the center; and a link pin 54 formed on the grounding member 51, being linked with the arm member 55, displacing vertically to project/retract the grounding member 51; and lock means 60 by which an engagement motion between the arm member 55 and the grounding member 51 is started immediately before the grounding member 51 reaches a descended end position and an engagement motion between a projection 61 and an engagement recess 62 is completed when the grounding member 51 reaches the descended end position. |
