ABSTRACT:
An improved disc-type key holder includes a circular disc with an annular sliding groove on its peripheral surface, and a multiplicity of key retaining rings slidably suspended in the groove. The disc is formed of two halves each having in the center of the disc surface a boss portion with a recess on the outside and a convexity on the inside and which are opposedly joined together to form a wheel-type body. On the disc surface of one of the two halves is provided a guide slit cutting and extending along the surface from a point on the peripheral wall toward the center to terminate in an enlarged end opening provided on the peripheral surface of the boss portion.
