<p>A connecting rod joint structure used for a trolley which can firmly hold the connecting rod in a rod insert hole only by using a small operating force. According to the connecting rod joint structure used for the trolley of the invention, the joint teat (36) of the rod insert hole (41) is enabled to concave-convexly engage with the joint through hole (12) of the connecting rod (11). Thus, the resting wall part of the joint teat (36) of a rest pad (20) needs no generation of elastic deformation like existing elastic block sheets, therefore improving the supporting strength of the joint teat (36) of the rest pad (20), holding the connecting rod (11) in the rod insert hole (41) more firmly than before. Additionally, a rod retainer (60) doesn't bear forces from other structure units of the connecting rod (11) and the rest pad (20) in a direction of pulling out from hole inside space (41S), therefore reducing the blocking force of the elastic block sheet (63) used for holding the rod retainer (60) in the hole inside space (41S), and reducing the insert/pulling resistance of the rod retainer (60).</p> |
