A wheel device with quick-releasing mechanism comprises a wheel body and an U-shaped movable member. The wheel body further has two tabs and an elastic element. The movable member further includes a first board having a first wall surface and a second wall surface each other in different planes, and an I-shaped second board restricted by the two tabs. When the movable member is at a first position and the first wall surface is aligned with a second section of a shaft, the wheel body can be escaped from the shaft. When the movable member is at a second position and the second wall surface is aligned with the second section of the shaft, the wheel body is restricted to the shaft by the movable member. In addition, the movable member having quick-releasing function is usually kept at the state of restriction due to the elastic element and/or a protrusion on the movable member.
