Abstract: A shock absorber structure of a castor wheel is disclosed. The bottom section of a leg is inserted with a mounting tube and the circumferential edge of the leg is mounted with a protective hood. A screw nut is used to lock the mounting tube and the protective hood to the bottom section of the leg. The interior of the protective hood and the mounting tube are inserted with an insertion shaft having a bottom section passed through between two bearings on the seat of the castor and a screw nut locks the seat at the bottom section of the through shaft such that the seat can be freely rotated with the through shaft as the shaft center. Further, the top and the bottom section of the through shaft are respectively mounted with a spring to form into top and bottom buffer. The buffer is effectively used as the shock produced as a result of uneven ground and allowing the castor wheel to pass an obstacle.
