<P>PROBLEM TO BE SOLVED: To simplify the structure of a transmission device by functioning a single port formed in a casing as a greasing route or an air breather route. <P>SOLUTION: Points requiring lubrication in the casing 1 include a drive shaft 4, a hub 3, and spline-connection part to the drive shaft 4. A cartridge 15 for greasing is installed so as to surround the drive shaft 4, a port 24 is drilled in the peripheral body part 10 of the casing 1 and covered by a plug 25, and a grease pipe 26 is connected to the plug 25. Further, a through hole formed in the plug 25 is formed in a stepped hole comprising a small diameter part 31 on the upper end side and a large diameter part 32. An annular passage 33 led to the inside of the casing 1 is formed in the large diameter part 32 on the outer peripheral side of the greasing pipe 26, and an air breather pipe 30 is connected to the large diameter part 32. <P>COPYRIGHT: (C)2007,JPO&INPIT |
