PROBLEM TO BE SOLVED: To provide an automatic transmission capable of disposing a parking lock mechanism in a compact manner in a transmission case accommodating a plurality of rotating shafts in parallel with each other, and being reduced in a size and a weight.SOLUTION: A virtual line L2 being in parallel with a straight line L1 passing through a center point O1 of an output shaft through hole 92d and a center point O2 of a counter shaft through hole 92e, and kept into contact with a lower half portion of an addendum circle C1 of a parking gear 73, is drawn. In a case where the center point O1 of the output shaft through hole 92d and the center point O2 of the counter shaft through hole 92e are respectively projected onto the virtual line L2, a rotating shaft holding portion 82b is disposed to intersect the virtual line L2 between a projection point P1 of the center point O1 of the output shaft through hole 92d and a projection point P2 of the center point O2 of the counter shaft through hole 92e to the virtual line L2.SELECTED DRAWING: Figure 5

    【課題】互いに平行な複数の回転軸を収納する変速機ケースの内部にパーキングロック機構をコンパクトに配置でき、小型化および軽量化できる自動変速機を提供すること。【解決手段】出力軸貫通孔92dの中心点O1とカウンタ軸貫通孔92eの中心点O2を通る直線L1と平行で、かつパーキングギヤ73の歯先円C1の下半部に接する仮想線L2を描出し、仮想線L2上に出力軸貫通孔92dの中心点O1とカウンタ軸貫通孔92eの中心点O2とを夫々投影した場合、回動軸保持部82bは、仮想線L2に対する出力軸貫通孔92dの中心点O1の投影点P1とカウンタ軸貫通孔92eの中心点O2の投影点P2の間で仮想線L2と交差するように配置される。【選択図】図5
