1. A vehicle seat comprising:
a seat back frame including:
left and right side frames that have a plate-shaped portion spreading along a vertical plane orthogonal to a rotational axis around a rotating shaft and extending upward along the vertical plane, a front wall that extends inward from a front edge of the plate-shaped portion and extends vertically from the rotating shaft, and a rear wall that extends inward from a rear edge of the plate-shaped portion and extends vertically from the rotating shaft; and
an upper frame that provides a link between the left and right side frames above the rotating shaft; and
a ventilation fan;
wherein:
the upper frame includes a front wall that is partitioned by an upper ridge line and a lower ridge line extending in a horizontal direction, an upper wall that spreads rearward from the upper ridge line, an upper standing wall that extends upward from a rear end of the upper wall, a lower wall that spreads rearward from the lower ridge line, and a lower standing wall that extends downward from a rear end of the lower wall;
an inner edge of the front wall of the side frame has a projecting piece that spreads to the inside from a virtual outline corresponding to a shape of the upper frame and is superimposed to a rear side of the front wall of the upper frame; and
the ventilation fan is fixed to the lower standing wall of the upper frame.
