Claims

[Scope of utility model registration request]

In a spray lubrication device having a spray nozzle for spraying a mist of lubricating oil onto a lubricated target part, the spray nozzle has a direction in which the angle at which the oil mist is sprayed is not opposite to the moving direction of the lubricated target part. A spray lubrication device characterized by having a jet nozzle inclined at a predetermined angle.
