The present invention is a device for supporting a wheel comprising a first member, which has a retention member and an axle operably configured to receive the wheel, and; a second member, which has a chock and an engagement portion. The second member is rotatably attached to the axle. Further, the second member is operably configured to have an unchocked position when not in use and selectively rotatable to a chocked position against the wheel to keep the wheel from rotating in at least one of a forward and reverse direction when the second member is use. Additionally, the retention member retains the engagement portion of the second member in the unchocked position when the chock is not in use.
