An operating lever of a vehicular seat according to the invention is provided at a front face, an upper face, or a back face of a seat (1) including a seat cushion (2) and a seat back (3), and includes a first lever (30) and a second lever (40). The first lever (30) and the second lever (40) are axially supported pivotably by each other on one end sides in length directions of the two levers (30) and (40). Other end side in the length direction of the first lever (30) is axially supported pivotably by the seat (1), and the axially supported other end side is connected to a lock mechanism capable of changing a state of an attitude of the seat (1) by way of a wire. Other end side in the length direction of the second lever (40) is formed as an operating portion (43). The attitude of the seat (1) can be operated while bending the first lever (30) in two stages around axial shafts (21) and (23) on sides of both ends in the length direction of the first lever (30) by operating an operating portion (43) of the second lever (40) in a direction of being remote from the seat (1).
