A shaft supporting structure includes a shaft having longitudinal end portions, with at least one of the end portions having at least one planar surface parallel to the axis of the shaft. A receiver part which receives the one end portion of the shaft has a regulate structure defining a recess through which the one end portion of the shaft can pass when the one end portion is moved in an insertion direction parallel to the planar surface. The regulate structure is operable to restrict radial displacement of the shaft after the shaft has been received in the receiver part and the shaft has been rotated so that the planar surface is no longer parallel to the insertion direction. A resilient pawl is operable to engage the planar surface and restrict rotation of the shaft in the receiver part. According to another embodiment, a receiver member and a cylindrical member have an assembled position in which the cylindrical member is disposed between one end portion of the shaft and the receiver member, the cylindrical member being placed in the assembled position by sliding the cylindrical member axially between the one end portion of the shaft and the receiver member such that the one end portion of the shaft is slidably received in the cylindrical member and the receiver member slidably receives the cylindrical member.
