indicates the connection direction with the motor. 5, the shaft seal part 6 is oil mist,
Reference numeral 8 indicates an air breather, 9a19b indicates first and second air vent pipes, and 10 indicates a baffle plate.
ギヤケース１のケース内圧圧部（後述）に第１エア抜き
管９ａと、第２エア抜き管９ｂとを設ける。A first air vent pipe 9a and a second air vent pipe 9b are provided in a case internal pressure section (described later) of the gear case 1.
第１図に示すように、増速ギヤ２を回転させると、ギヤ

れている。As shown in Fig. 1, when the speed increasing gear 2 is rotated, due to the rotation of the gear, the inside of the gear case 1 is caused by 20 rotations of the gear.
Due to the centrifugal force inevitably generated on the gear surface, as shown in FIG. 1, there is a negative (-) pressure around the shaft seal 5, and a positive (+) pressure elsewhere. Air vent pipes 9a and 9b are arranged in this positive pressure section.
エア抜き管９ａ、９ｂの配設によって油ミストは排出さ
れ、ギヤケース１内は負圧に保たれ、油ミスト６が軸封
部５より外部に漏出することはなくなる。By disposing the air vent pipes 9a and 9b, the oil mist is discharged, the inside of the gear case 1 is maintained at a negative pressure, and the oil mist 6 is prevented from leaking to the outside from the shaft seal portion 5.
また、第２図に示すように、前記エア抜き管９ａ、９ｂ
