The pad 20r is supported by a buckle 50 as shown in FIG. Therefore, in the configuration of Comparative Example 1, even if a load is input to the seating surface side, the pad 20r is less likely to drop between the right side frame 31 and the right spring member 32R. .

(Comparative example 2)
FIG. 5 is a top view showing a conceptual configuration of the vehicle seat 1 according to Comparative Example 2 when viewed from above. FIG. 6 is a cross-sectional view of the seat cushion 2 taken along line BB in FIG. FIG. 7 is a perspective view showing a configuration of pads on the right side surface portion 2SR of the vehicle seat 1 of FIG.

As shown in FIG. 5, the vehicle seat 1 includes a seat cushion 2, a seat back 3, and a headrest 4, similar to FIG. The seat cushion 2 shown in FIG. 5 has a configuration in which the removed portion 100 is removed from the seat cushion 2r shown in FIG. The right side portion 2SR of the seat cushion 2 has a rear portion 5, a middle portion 7 and a front portion 6. As shown in FIG.
