PROBLEM TO BE SOLVED: To provide an automotive seat that has improved appearance and can easily by assembled. SOLUTION: A shaft 19 is connected to a lumber support part 18 provided inside a seat back 11. In the shaft 19, a full-circumferential groove 19a is provided, and a tooth-formed part 19c is formed on the tip side of it. A lever 3 compises a handle part 31 and a shaft part 32. In an inner circumferential surface of the shaft 32, a tooth-formed part 32c in an internal gear form corresponding to the tooth-formed part 19c in the shaft 19 is formed. In an outer circumference of the shaft part 32, a pair of notches 32e are provided. A spacer 4 comprises a cylindrical base part 41 and a circular flange part 42. An inner diameter of the base part 41 is a little larger than an outer diameter of the shaft part 32. A snap 5 is fitted in the groove 19a through the notches 32e the time of assemblage. After assemblage, the spacer 4 has a larger diameter than a hole in the seat back 11, so it is slidable in an axial direction.
