<p>A pinion shaft fixing structure for a planetary gear, said structure having a shaft-side pin hole (45b) formed in a pinion shaft (40), having a carrier-side pin hole (20B) formed in a carrier (20), and having the pinion shaft (40) fixed to the carrier (20) by a fixing pin (70) passing through both the shaft-side pin hole (45b) and the carrier-side pin hole (20B). When an oil catch plate (60) is mounted to the carrier (20), a marginal part (65) of the oil catch plate (60) covers an opened insertion opening (the insertion opening into which the fixing pin (70) is inserted) in the carrier-side pin hole (20B). Consequently, the number of man-hours for assembly of the planetary gear can be reduced, and the production cost can be decreased.</p> |
