The utility model relates to a life saving slow-lowering device in a high-rising building with direct steel wire transmission, which is provided with an outer shell, an optical axis and a steel cable which penetrates through an inner screw thread sleeve to wind on the optical axis. One end of the optical axis is sheathed with a centrifugal block seat which is respectively pivoted with an L-shaped lever, one end of each lever is provided with a centrifugal block, and a draw rod which is arranged in the optical axis is connected with a baffle plate nut. The other end of the lever is extended between the centrifugal block seat and the baffle plate nut, the other end of the optical axis is connected and provided with a friction rotor plate, and the outer shell is inserted with a friction static plate. The utility model has the advantages that the optical axis with small diameter can be adopted, the utility model needs no speed increasing mechanism, and the optical axis drives the centrifugal block to control a speed limiting mechanism directly. The utility model has simple structure and high stability.
