Provided is a brake device for a vehicle seat, which includes a tooth plate installed on an unlock member and coupled to a pinion shaft in a serration manner to constrain rotation of the pinion shaft. Therefore, even when the rotational constraint force by brake rollers is reduced due to the repeated loading, the rotation of the pinion shaft is reliably suppressed by the tooth plate, thereby preventing seat sagging.
