Spring castor utility model adopts the following technical scheme of a suspension function castor including: a shaft socket, a steering shaft and pin joint to connect on the bottom surface of the object to an object; A suspension mechanism, and shaft socket joint configuration, suspension mechanism includes: a body, the c2: extend outward from shaft, on both sides of the seat body peripheral extension is equipped with two phase in the face of the side panel, make body are picture type and set to form one for the space, the two sides adjacent axis at the bottom of the socket location to open a shaft hole respectively, and in the location of the seat body placed adjacent to the space of the top is equipped with a first must have a convex column; A connecting arm, pursuant to the first pin joint position defines a section, a second pin joint section and the connection between the first and second pin joint section, where the first pin joint setting between the two sides, the first pin joint section has a first pin hole, and through a shaft rod wear in two axle hole and a pin hole, make the connection arm swing in a body, the free end of the second pin joint section is equipped with a groove, let trough the connection section of extension, and throughout the second pin joint section has a capacity of groove second pin hole; A twisted, with its top surface has a first a convex column to keep the relative position of the second positioning convex column, and there is a long twisted seat extends outward at the bottom of the pin joint, long pin joint block in capacity in the groove, the long pin joint block corresponding to the second pin hole has a third pin hole; At least one limit lobe, it is set in the body below the shaft hole location nearby, limit lobe selective rely on top face in the lateral connection arm, to limit the extent of the connecting arm swinging down; And a spring, set between the seat body and twisted, and placed in the space of the springs at both ends, respectively, set in the first must have a convex column and second positioning convex column, provide the first and second spring positioning convex column elastic binding, to keep the first and second positioning convex column position; And two casters, each with a round hole, and through a shaft through the second pin joint section of the second pin hole, long block pin joint third pin hole and two castor wheel hole, and make the gyration and 2 caster wheel spin in connection arm respectively. The second pin joint section of the relative link arm side facing prominent, limit convex department as the second pin joint section extends to form a rely on, rely on the selective rely on in the second pin joint section and limit the scope of the connecting arm swinging down.
