A knitting method of a tubular knitted fabric wherein, when knitting the tubular knitted fabric using a flat knitting machine having a front and back needle bed (FB, BB) in which at least one of the front and back needle beds (FB, BB) is capable of being racked in a traverse direction and stitches are transferable between the front and back needle beds (FB, BB), a back stitch is rotated by positioning a stitch β, which is newly formed following a stitch α at an end in a knitting width direction of a one side knitted fabric portion held on one needle bed (FB or BB), on an outer side of a knitting width of an other side knitted fabric portion with respect to a stitch γ at an end in a knitting width direction of the other side knitted fabric portion held on the other needle bed (BB or FB) facing the one needle bed (FB or BB) the knitting method of a tubular knitted fabric being characterized by: assuming the direction from the stitch α toward the knitted fabric portion is an inner side and the opposite direction is an outer side in a movement direction of a yarn feeder along an extending direction of the needle beds (FB, BB), a step 1 of moving the yarn feeder toward the outer side, forming the stitch γ during the movement, and positioning the yarn feeder on the outer side of the stitch α; a step 2 of transferring the stitch α to an empty needle on the outer side of the knitting width with respect to the stitch γ on the other needle bed (BB or FB); a step 3 of moving the yarn feeder positioned on the outer side of the stitch α toward the inner side to be positioned on the inner side of the stitch α; a step 4 of feeding a knitting yarn to the knitting needle of the other needle bed (BB or FB) holding the stitch α while moving the yarn feeder positioned on the inner side of the stitch α toward the outer side, and forming the stitch β to become the back stitch when the tubular knitted fabric is seen from the outer side of the tube; and a step 5 of moving the yarn feeder toward the inner side and forming a new stitch ε following a stitch δ proximate to the stitch α in the step 1. assuming the direction from the stitch α toward the knitted fabric portion is an inner side and the opposite direction is an outer side in a movement direction of a yarn feeder along an extending direction of the needle beds (FB, BB), a step 1 of moving the yarn feeder toward the outer side, forming the stitch γ during the movement, and positioning the yarn feeder on the outer side of the stitch α; a step 2 of transferring the stitch α to an empty needle on the outer side of the knitting width with respect to the stitch γ on the other needle bed (BB or FB); a step 3 of moving the yarn feeder positioned on the outer side of the stitch α toward the inner side to be positioned on the inner side of the stitch α; a step 4 of feeding a knitting yarn to the knitting needle of the other needle bed (BB or FB) holding the stitch α while moving the yarn feeder positioned on the inner side of the stitch α toward the outer side, and forming the stitch β to become the back stitch when the tubular knitted fabric is seen from the outer side of the tube; and a step 5 of moving the yarn feeder toward the inner side and forming a new stitch ε following a stitch δ proximate to the stitch α in the step 1.
