Claim:
A slide rail unit, comprising: a body side rail attached to a body in which an object is accommodated; and an object side rail attached to the object and slidable relative to the body side rail; and a retainer interposed between the body side rail and the object side rail to retain a rolling member between the body side rail and the object side rail, the rolling member rolling between the body side rail and the object side rail when the object side rail and the body side rail slide relative to each other, the retainer having a bottom wall section extending in a longitudinal direction of the retainer and having a pair of arm-shaped sections extending upward from respective ends in a width direction of the bottom wall section, wherein the body side rail and the object side rail are bent around an axis parallel to a width direction of the body side rail and the object side rail, and one of said body side rail and said object side rail is fitted to an inside portion of an other of said body side rail and said object side rail, such that said one of said body side rail and said object side rail fitted to the inside portion is slidable relative to the other of said body side rail and said object side rail, and said body side rail and said object side rail each have a portion bent in a circular arc shape to guide the object so that the relative sliding of the body side rail and the object side rail guide the object along a circular arc locus out from the body in which the object is accommodated.
