To provide an auxiliary wheel device for a caster which can achieve space-saving when arranging a caster and an auxiliary wheel.SOLUTION: An auxiliary wheel device for a caster comprises: a caster which rotates in a travel direction of a vehicle body and in which steering angle is freely changed when the vehicle body turns; and an auxiliary wheel which is arranged in front of or in the rear of the caster in the travel direction, and arranged at the height where the auxiliary wheel is not grounded when the caster is grounded. The caster does not interfere with the auxiliary wheel at the initial position of the auxiliary wheel, and the steering angle is changed when the auxiliary wheel is grounded so that the caster does not interfere with the auxiliary wheel.SELECTED DRAWING: Figure 1
