摘要： PROBLEM TO BE SOLVED: To provide a breather device for an automatic transmission discharging, into the atmosphere, high-pressure air flowing from a case into a breather chamber, and smoothly returning to the case, oil flowing into the breather chamber together with the high-pressure air.
SOLUTION: The breather device 20 for an automatic transmission has a main body part 21 attached to an upper part of a case. The case houses a power transmission mechanism part together with an ATF. A breather chamber 22 is formed in the main body part 21. The main body part 21 is provided with: a first connecting pipe 24 connected with a communication hole disposed to the upper part of the case to communicate the inside of the case with the breather chamber 22; and a second connecting pipe 25 communicating the breather chamber 22 with the air at a position above the first connecting pipe 24 in a perpendicular direction and separated in a horizontal direction. A downward inclination is formed to an inner bottom face 22c of the breather chamber 22. The downward inclination leads the ATF flowing into the breather chamber 22 through the first connecting pipe 24, to the first connecting pipe 24 side.
