Abstract
A caster device for a pipe leg includes a caster unit, a mounting unit, and a braking unit. The caster unit includes a wheel seat subunit, a caster subunit that is rotatably connected to a bottom end of the wheel seat subunit, and a protection subunit that is located between the wheel seat subunit and the caster subunit. The mounting unit is mounted to the wheel seat subunit and is adapted to be mounted to the pipe leg. The braking unit extends through the protection subunit and the wheel seat subunit into the mounting unit, and is movable in an up-down direction between a braking position, in which the braking unit projects out of the protection subunit and is in contact with the caster subunit so that the caster subunit is refrained from rotating, and an initial position, in which the braking unit is spaced apart from the caster subunit.
