PROBLEM TO BE SOLVED: To provide a wheel device of a model plane operated by a wireless communication that alleviates the impact during a landing operation to prevent damage to the wheel device and the model plane body.SOLUTION: A wheel device body 2a is attached to an indirect attachment member 5, and a wheel device 2 is attached to a model plane body 1a. By a recess 7 provided to the model plane body 1a, one of pieces 5a of the indirect attachment member 5 does not directly contact the model plane body 1a. The indirect attachment member 5 has a shape of an angle, and is bent when an impact is received to alleviate the impact. Thereby, damage to the wheel device 2 and the model plane body 1a can be prevented with a simple configuration that does not require a reinforcement member.
