Claim Text:
1. A vehicular automatic transmission, comprising: a housing; an input shaft which is sustained to be rotatable around a rotation shaft line in the housing; an output shaft which is sustained to be rotatable around the rotation shaft line in the housing; single pinion type first, second and third planetary gear sets which are sustained in parallel coaxially with the rotation shaft line in the housing as the input shaft and a carrier of the first planetary gear set are linked to each other, the output shaft and a carrier of the third planetary gear set are linked to each other, the carrier of the third planetary gear set and a ring gear of the second planetary gear set are linked to each other, and a sun gear of the third planetary gear set and a ring gear of the first planetary gear set are linked to each other; a first brake which selectively fixes a ring gear of the third planetary gear set with respect to the housing; a first clutch which selectively links the ring gear of the third planetary gear set and a carrier of the second planetary gear set; and a switching element which blocks the link between the input shaft and the carrier of the first planetary gear set, and switches the input shaft to be in a switched state in which the input shaft is linked to a sun gear of the second planetary gear set and a sun gear of the first planetary gear set, wherein, in a reverse gear shift stage, the first clutch is in an engaged state, the first brake is in a fixed state, and the switching element is in a switched state.
