A wheel unit 1 is composed of a stopper portion 70 installed in a main body portion 20 and a stopped portion 14 installed in a wheel and tire assembly portion 10. The stopper portion 70 is an electromagnet. When a voltage is applied to the stopper portion 70 at the time of turning a power source on with an electrode terminal portion 50 nested in a main shaft portion 40 as a contact, the electromagnet generates a magnetic field and is magnetically attached to the stopped portion 14 formed of a metal piece, whereby the rotation of the wheel and tire assembly portion 10 can be restricted.
