The utility model discloses a pulley mechanism and a sliding rail door. The pulley mechanism comprises a shell, a swing support, a pulley, an elastic element and a limiting structure. The shell is installed in an installation groove of a bottom frame of the door body, the swing support is connected with the shell through a first pivot shaft, the pulley is connected with the swing support through a second pivot shaft, and the elastic element is connected between the shell and the swing support and used for driving the swing support to swing downwards, so that the pulley is arranged on the guide rail in a riding mode. The limiting structure is arranged between the shell and the swing support and used for limiting the swing amplitude of the swing support, and the situation that the pulley is disengaged from the guide rail due to too large self-adaptive adjustment amplitude can be avoided. When an obstacle exists on the guide rail, the pulley can move upwards in a self-adaptive mode to cross the obstacle, the der
