合がある。 The opening end surface of the first chamber on the pinion case side is formed in an annular shape, and the opening end surface of the second chamber on the same case side is formed in a gate shape that bulges out from the annular portion. If the packing is clamped with the tightening force of the coupling bolt only at the end face of the pinion, the surface pressure on the packing will become uneven, resulting in insufficient sealing between the end face of the second chamber opening and the end face of the pinion case opening, which will cause the lubrication to deteriorate. Problems may occur if oil leaks to the outside or water enters the center bracket.
