Provided are a slewing frame of a work machine and a method of assembling a slewing frame of a work machine where the slewing frame is separable into at least two front and rear members, and an operation of connecting these two members can be easily performed. A slewing frame (120) is separable into a front frame (121) and a rear frame (122). When a pin fitting portion (742) of a rear frame (122) is fitted on a positioning pin (731) of a front frame (121), and the rear frame (122) is rotated downward, at a position where a front pin hole (73A) and a rear pin hole (74A) are aligned with each other, a contact portion (743A) of the rear connecting portion (74) is brought into contact with a rotation preventing portion (732). As a result, a connecting pin can be easily inserted into the front pin hole (73A) and the rear pin hole (74A).
