To provide a caster which can lock or release the lock with a small force in a reliable manner, and to provide a dolly and a bed.SOLUTION: A caster 10 includes: a jig 11 fixed to a transported object; a wheel 14 in which a shaft 13 is connected to a rotation center; a shaft case 12 which pivotally supports the wheel 14 and the jig 11 and connects the wheel 14 with the jig 11; a stopper member 24 which may come into contact with a wheel 39 of the wheel 14; a stopper mechanism 15 having a toggle structure including the stopper member 24; and an operation mechanism 18 which deforms the toggle structure to cause the stopper member 24 to contact with the wheel 39 and thereby stop rotation of the wheel 14. The stopper mechanism 15 presses the stopper member 24 to the wheel 39 at a substantially right angle.SELECTED DRAWING: Figure 4
