An automatic speed reducing wheel includes a wheel unit (10) and a speed reducing unit (20). The wheel unit (10) includes a wheel seat (11), a wheel axle (12) passing through the wheel seat (11), and a roller (13) rotating about the wheel axle (12). A plurality of blockers (1312) is disposed on one side of a wheel frame (131) in adjacent to an edge thereof in a radiation shape arrangement. The blockers (1312) rotate along with the roller (13). The speed reducing unit (20) includes a fixing seat (21, 24) and a sliding member (22, 25). The fixing seat (21, 24) is on one side of the roller (13) and includes a sliding bore (212, 241). The sliding member (22) is slidably disposed in the sliding bore (212) and includes an elastic portion (222) having a blocking portion (223). When the roller (13) moves downhill, the blocking portion (223, 252) of the sliding member (22, 25) protrudes out of an outer side of the sliding bore (212, 241) to interrupt a rotation route of the blockers (1312, 1313), achieving a speed reducing effect.
