Abstract
This invention relates to a two piece plastic idler pulley formed of identical portions including a hub, a web and a rim with identical fastening means on the two half portions which permit the two portions to be joined together as the idler pulley. The hub of the idler pulley has a through bore which is inversely tapered whereby the hub will flex when subjected to a workload and will capture the lubricant internally of the bore. The rim carries diverging means which extend radially and laterally outwardly from the rim to insure proper seating of power transmission means such as a belt. The diverging means also is capable of engaging the power transmission belt when it is inadvertently seated on the hub to move the belt into seated relationship on the rim for proper operation of the device.
