The invention discloses an idler wheel of a compartment type elevator. The section of a metal idler wheel framework is in a T shape. The longitudinal part is of a hollow structure. A limiting check ring stretching in the radial direction of a through hole is arranged on the edge of the through hole, on the same side of the transverse part, of the longitudinal part, a first arc-shaped ring groove is formed in the inner hole wall of the through hole, a metal shaft sleeve is arranged in the through hole, a second arc-shaped ring groove opposite to the first arc-shaped ring groove is formed in the outer surface of the metal shaft sleeve, and balls are annularly distributed in a cavity formed by the first arc-shaped ring groove and the second arc-shaped ring groove jointly. The longitudinal part of the metal idler wheel framework is sleeved with a non-metal outer ring, one side face is connected with the transverse part of the metal idler wheel framework in a blocking manner, the longitudinal part of the metal idler wheel framework is further sleeved with a metal gland, and the metal gland, the metal shaft sleeve and the metal idler wheel framework are riveted. The technical purpose of reducing the production cost of the idler wheel of the compartment type elevator is achieved, and the production cost of the idler wheel is low.
