To provide a vehicle sensor, a seat-belt retractor, and a seat-belt device that can reduce noise during normal traveling of a vehicle.SOLUTION: A vehicle sensor 5 comprises: a spherical mass body 51; a casing 52 comprising a lower plate surface 52a that rotatably supports the mass body 51; and an actuator 53 disposed above the mass body 51 and configured to be engageable with a tooth portion 61f of a lock gear 61 when the mass body 51 is moved by an inertial force, in a predetermined direction. The casing 52 is configured not to allow portions other than the lower plate surface 52a to come into contact with the mass body 51 when the mass body 51 revolves around the lower plate surface 52a. The actuator 53 is configured not to allow portions other than an upper plate surface 53a to come into contact with the mass body 51 when the mass body 51 revolves around the lower plate surface 52a.SELECTED DRAWING: Figure 2

    【課題】車両の通常走行時における騒音を低減することができる、ビークルセンサ、シートベルトリトラクタ及びシートベルト装置を提供する。【解決手段】ビークルセンサ5は、球形の質量体51と、質量体51を公転可能に支持する下皿面52aを備えたケーシング52と、質量体51の上部に配置され質量体51が慣性力で所定の方向に移動した際にロックギア61の歯部61fに係合可能に構成されたアクチュエータ53と、を備え、ケーシング52は、質量体51が下皿面52aを公転する際に下皿面52a以外の部分が質量体51と接触しないように構成されており、アクチュエータ53は、質量体51が下皿面52aを公転する際に上皿面53a以外の部分が質量体51と接触しないように構成されている。【選択図】図2
