Provided is a wheel support structure for self-propelled electronic device which takes safety into account, by not jumping out vigorously with strong force when a drive wheel protrudes to the exterior. The wheel support structure for self-propelled electronic device is characterized by comprising; a drive wheel which supports and drives a housing on a floor surface; a swinging support unit which rotatably supports the drive wheel and mounts the drive wheel to the bottom part of the housing so as to be able to swing in a vertical direction about the swinging axle; and a biasing mechanism which includes a biasing member which biases the drive wheel so as to swing downwards, wherein the biasing mechanism biases the winging support unit downwards by means of the biasing member in a state in which the housing is placed on the floor, and the biasing towards the swinging support unit by the biasing member is released in a state in which the drive wheel is not in contact with the floor surface.
