- the wall member 40 in combination with the fact that the main body portion 42 and the cover portion 43 are integrally formed and that the wall member 40 is fixed to the upper rib 22 by a plurality of attachment portions 41a, 41b, 41c, the wall member.
- the strength of 40 can be improved, and the wall member 40 can be more closely attached to the outer surface of the upper rib 22.
- the wall member 40 can be molded by injection molding, the wall member 40 can be easily formed of plastic such as resin.
- the upper standing surface 43b 1 on which the oil discharged from the notch 22a first comes into contact is configured to be flat.
- the housing is provided from the transmission case side. It is good also as a taper surface inclined toward the case side.
- the upper elevation ⁇ 43 b 1, and a tapered surface inclined towards the housing case side to the transmission case side collect the discharged oil from the notch 22a to efficiently guide passage 45, the oil from the guideway 45
- the discharge part 43b may be configured to discharge the gas toward the housing case.
- the transmission case side of the lower elevation ⁇ 43b 2 forming the guide path 45 a discharge hole communicating the inner surface 43b and the outer surface 43a of the cover portion 43 is provided, there is no momentum, the transmission case side of the guide path 45 It is also possible to configure so that the oil accumulated in can be discharged out of the cover part 43.
- the automatic transmission with six forward speeds has been described, but the present invention is naturally applicable to any stepped automatic transmission such as, for example, eight forward speeds.
- the present invention may be applied to any transmission such as a three-axis continuously variable transmission, a hybrid drive device, or a manual transmission as long as it is a vehicle transmission.
- the inventions disclosed in the first and second embodiments may naturally be combined in any way.
- the vehicle transmission according to the present invention can be mounted on a passenger car, a truck, a bus, and the like, and is particularly suitable for use in a vehicle transmission such as a multistage or continuously variable automatic transmission or a hybrid drive device. It is.
