FIG. 1 shows a grease applying device 10, which has an air dispenser 11 connected by an air supply tube P and a syringe 12, and from the syringe 12 through a grease supply tube Pg. The configuration is such that grease is fed into the applicator main body 13 on which the component W is set.
In the applicator main body 13, a target part W is set and a grease application location Wg is allowed to enter, and an application space R is formed in which the grease from the grease supply tube Pg is ejected by means described later.

  The air dispenser 11 appropriately controls the air sent from the facility in the factory via the air supply tube P by the control means (not shown) from the air supply tube P on the outlet side to the syringe. 12 is sent.

  Although details are not shown, the syringe 12 temporarily stores the grease to be applied by a supply means from a storage means (not shown), and the air discharged from the air supply tube P on the outlet side of the air dispenser 11 is used to apply the main body of the applicator. 13 is a container for feeding grease to 13.

  The applicator main body 13 forms a central application space R so that a grease application location Wg of the target component W can be inserted from above. The application space R is formed in a cylindrical shape, and a grease supply nozzle 14 is formed on the inner wall constituting the application space R. In this case, as shown in FIG. 2, the grease supply nozzles 14 are plural (here, four), and the nozzle tips are allowed to enter the application space R radially at equal intervals. Of course, the number of grease supply nozzles 14 is not limited to four, and an appropriate number of grease supply nozzles 14 can be provided according to the grease application location Wg of the target component W to be applied.
