A movably mounted furniture part includes a torque-transmitting shaft, especially a synchronizing rod. The shaft has at least two sub-shafts, one sub-shaft being a rod-type component and the other sub-shaft being a connecting part. A connecting device connects the rod-type component to the connecting part, and can include at least one spring that resiliently holds the rod-type component and the connecting part together. A locking part is formed on the rod-type component and/or on the connecting part and/or can be mounted thereon, with the locking part securing the rod-type component and the connecting part against detachment.
