The present invention relates to a planetary gear device for a vehicle, comprising: a ring gear portion having a plurality of ring teeth portions formed at an internal side thereof; a carrier portion having a plurality of carrier teeth portions formed in the ring gear portion and individually circumscribed to be engaged with the ring teeth portions; a sun gear portion inserted into the carrier portion, and having a plurality of sun teeth portions selectively circumscribed to be engaged with any one of the carrier teeth portions; and an operating portion moving the sun gear portion in an axial direction to control connection between the carrier teeth portions and the sun teeth portions. Therefore, a size of a product is reduced, and at the same time, multiple shifting of a gear can be performed.
