Claims

[Scope of Claim for Utility Model Registration] A horizontal rotary rack in which a plurality of racks are installed between a pair of left and right endless drive chains, and each rack is configured to rotate along a long vertical circulation path in the front and rear horizontal directions. Of the chain rollers supported by the link connecting pin between the links of the endless drive chain, only the chain roller supported by the link connecting pin supporting the rack alone is supported via rolling bearings, and the other chain rollers are supported by rolling bearings. is a horizontal rotating rack made of synthetic resin rollers supported on the link connecting pin without using rolling bearings. Among the links of the endless drive chain, a protrusion is provided only on the pair of left and right links connected by a link connecting pin that supports the single rack, and the protrusion moves while sandwiching the chain guide rail from both left and right sides. 2. A horizontal rotary rack according to claim 1, wherein said rack is configured to do so.
