PURPOSE: A planetary gear speed increasing device capable of regular rotational outputting in single direction is provided to enable regular rotational outputting in single direction of the bidirectional rotation input of an input shaft by comprising first and second one way clutches. CONSTITUTION: A first planetary gear set(PG1) comprises at least 3 rotation elements. One rotation element is connected to an input shaft(10). Two rotation elements among the three rotation elements of a second planetary gear set(PG2) is directly connected to the first planetary gear set. A first one way clutch(OWC1) is arranged at an output shaft(20). The first one way clutch is arranged to selectively receive the power of one rotation element of the first planetary gear set. A second one way clutch(OWC2) is coaxially arranged with the first one way clutch. The first one way clutch is arranged to selectively receive the power of one rotation element of the second planetary gear set. The first planetary gear set comprises a first sun gear(S1), a first planetary carrier(PC1), and a first ring gear(R1). The second planetary gear set comprises a second sun gear(S2), a second planetary carrier(PC2), and a second ring gear(R2). |
