To provide a belt transmission device which can inhibit increase of operation sound caused by inclination of a driving pulley, and to provide a steering device.SOLUTION: A belt transmission device includes: a housing; a motor fixed to an outer surface of the housing; a cylindrical driving pulley 31 which integrally rotates with an output shaft 18a of the motor; a driven pulley rotatably supported within the housing; a belt wound around the driving pulley 31 and the driven pulley; and a joint 81 which is provided within the driving pulley 31 and couples the output shaft 18a to the driving pulley 31 in a manner that the output shaft 18a can swing along a direction in which tensile force of the belt 33 acts. The joint 81 has: a torque transmission part 83 which is supported within the driving pulley 31 so that the torque transmission part 83 can swing along a direction in which the tensile force of the belt 33 acts; and a connection part 82 which connects the torque transmission part 83 to a tip part of the output shaft 18a.SELECTED DRAWING: Figure 7

    【課題】駆動プーリの傾きに起因する作動音の増大を抑制することができるベルト伝動装置およびステアリング装置を提供する。【解決手段】ベルト伝動装置は、ハウジングと、ハウジングの外面に固定されるモータと、モータの出力軸18aと一体的に回転する筒状の駆動プーリ31と、ハウジングの内部において回転可能に支持される従動プーリと、駆動プーリ31と従動プーリとに巻き掛けられるベルトと、駆動プーリ31の内部に設けられて出力軸18aを駆動プーリ31に対してベルト33の張力が作用する方向に沿って揺動可能に連結する継手81と、を有している。継手81は、駆動プーリ31の内部においてベルト33の張力が作用する方向に沿って揺動可能に支持されたトルク伝達部83と、トルク伝達部83と出力軸18aの先端部とを連結する連結部82と、を有している。【選択図】図7
