PROBLEM TO BE SOLVED: To achieve improvement in a brake strength while reducing a deformation volume (displacement of a rotation angle) of a pinion gear with respect to a load acting on the pinion gear.SOLUTION: A brake control system of a vehicle seat adjuster comprises a brake mechanism part 9 and a drive mechanism part 10. The brake mechanism part 9 is configured from a brake housing 8 comprising a housing body 11 and a brake drum 13, two sets of clamp members 14, 16 having a clamp surface 26, an output shaft 12 having a pinion gear 12d, and composite springs 15, 17 which energize respective clamp members 14, 16. The clamp surface 26 of each clamp member 14, 16 has a large diameter clamp surface, and a projection part which is so formed as to be separated from the large diameter clamp surface, and has a minute space between itself and a brake surface 13a of the brake drum 13 at a normal time.SELECTED DRAWING: Figure 7

    【課題】ピニオンギヤに作用する荷重負荷に対してピニオンギヤの変形量(回転角の変位)を小さくすると共に、制動強度の向上を図る。【解決手段】ブレーキ機構部9と駆動機構部10とを備え、ブレーキ機構部9は、ハウジング本体11とブレーキドラム13とからなるブレーキハウジング8と、クランプ面26を有する二組のクランプ部材14,16と、ピニオンギヤ12dを有する出力軸12と、各クランプ部材14,16を付勢する複合ばね15,17と、から構成される。各クランプ部材14,16のクランプ面26は、大径クランプ面と、この大径クランプ面から離間して形成されて、通常時にはブレーキドラム13の制動面13aとの間に微小隙間を有する突起部と、を有している。【選択図】図7
