Scroll fluid machine having injection holes through which lubricant is injected to the orbiting bearing
The purpose of the present invention is to provide a scroll fluid machine configured so that, during maintenance, grease can be easily supplied to a bearing regardless of an installation environment, thereby improving work efficiency. The present invention provides a scroll fluid machine characterized by comprising: a stationary scroll obtained by forming a wrap section on an end plate; an orbiting scroll obtained by forming a wrap section on an end plate such that the wrap section faces the wrap section of the stationary scroll; a drive shaft for driving the orbiting scroll; an orbiting bearing for supporting the drive shaft relative to the orbiting scroll; and a plurality of pouring openings for pouring a lubricant into the orbiting bearing from the outside.
