Rotating body and elevator

The invention provides a rotating body and an elevator using the same, which can prevent lubricant used by a bearing from leaking. The present invention is provided with: a main shaft serving as a rotating shaft; a first structure rotatably supported by the main shaft via a bearing; and a second structure which is attached to the first structure via a liquid gasket and seals a space in which the bearing is provided. In addition, the present invention is provided with: a bolt hole provided from the second structure body to the first structure body side; the fixing bolt is in threaded connection with the bolt hole and is used for fixing the second structural body to the first structural body; and a vent hole which is provided in the first structure, communicates with the bolt hole, and communicates with a space different from the space in which the bearing is provided. 本发明提供一种旋转体以及应用了该旋转体的电梯，能够防止轴承所使用的润滑剂泄漏。具备：主轴，其成为旋转轴；第一结构体，其经由轴承以能够旋转的方式支撑于主轴；以及第二结构体，其经由液状垫圈安装于第一结构体，对设置有轴承的空间进行密封。另外，还具备：螺栓孔，其从第二结构体设置到第一结构体侧；固
