PROBLEM TO BE SOLVED: To provide a mobile scaffold device in which frame bodies formed by combining posts and horizontal members are arranged in parallel at intervals, and braces and scaffolding boards bridge between and connect the opposed frame bodies to assembly them; the posts being provided with casters in the lower ends so that only a small force is required for movement and stably turnable during movement; thus remarkably improving stability of a mobile scaffold. SOLUTION: The casters provided in the lower ends of at least four posts or more located at corner parts consist of two wheels, respectively, rotatable independent to each other; the respective two wheels comprising tires 20 including tires 20b fit to the outer peripheries of wheel parts 20a, coaxially held on an axle 34.
