Abstract: A sealing agent (25) sent from a nozzle tube (36) to a nozzle main body (37) is passed through a main body flow channel portion (37a), a connecting portion (37c), a first flow channel portion (37b), and plural second flow channel portions (37d), sent to a chamber (37e), and discharged from a nozzle port (37f) to the outside. Since the second flow channel portions (37d) are smaller than a downstream end of the first flow channel portion (37b), the sealing agent (25) in the first flow channel portion (37b) is vigorously sent to the chamber (37e), and discharged from the nozzle port (37f) to the outside. As a result, substantially the same quantity of the sealing agent (25) is discharged in the entire range of the chamber (37e).

Abstract: An application unit (13) comprises a rotation unit (26) and a support unit (27). The rotation unit (26) comprises a nozzle unit (28), a nozzle support part (29), a body base (30), a first supply part (31), a second supply part (32), a third supply part (33), a valve (34), and a motor (35). The nozzle support part (29) rotatably supports the nozzle unit (28) such that the central axis of the nozzle unit (28) is inclined with respect to the rotation axis of the rotation unit (26).
