To provide a brake device for automobile seat which contributes down-sizing of a device, and a method for manufacture thereof.SOLUTION: In this brake device 7, a pair of regulation parts 121e, 122e, which are projected from an outer peripheral part of a deformed shank 12c, are brought in contact with an inner bottom surface of a housing 11 to regulate axial movement of a pinion shaft 12 to a seat side. Therefore, down-sizing of the pinion shaft 12 in an axial direction can be achieved by only an axial dimension of a flange part compared to when the flange part is provided in series in the axial direction with respect to the deformed shank 12c, thereby enabling contribution to down-sizing of the brake device 7.SELECTED DRAWING: Figure 5

    【課題】装置の小型化に寄与する自動車用シートのブレーキ装置およびその製造方法を提供する。【解決手段】本発明に係るブレーキ装置7では、異形軸部12cの外周部に突設した一対の規制部121e,122eをハウジング11の内底面に当接させて、ピニオン軸12のシート側への軸方向移動を規制している。このため、異形軸部12cに対して軸方向に直列にフランジ部を設ける場合と比べて、当該フランジ部の軸方向寸法の分だけ、ピニオン軸12の軸方向の小型化を図ることが可能となり、ブレーキ装置7の小型化に寄与することができる。【選択図】図5
