In the breather chamber 2, a 1/4 circular hole 11 is bored in the corner of the side wall 10 at a position 8 where the air-fuel mixture changes direction, that is, a position 8 where the side wall 9 and the bottom wall 6 butt each other. In the side wall 10 including this hole 11,
A cylindrical shaft support 12 whose shaft center line l is lower than the inner surface of the bottom wall 6 is formed. One end of a hollow shaft 13, which opens only one end from the outside of the breather chamber 2, is fitted and supported by this cylindrical shaft support 12. A torque transmission gear 14 is rotatably mounted on the torque shaft 13, and in order to guide oil to the bearing of the torque transmission gear 14,
A thin hole 15 extends from the inner circumferential surface of the hollow shaft 13 to the outer circumferential surface which is the bearing part of the torque transmission gear 14.

In the breather chamber structure configured as above,
The mixture of gas and oil in the engine enters the breather chamber 2 through the hole 3, changes direction and flows within the breather chamber 2, so that the oil adheres to each wall surface and is separated from the gas. The gas is discharged from the gas outlet 5 in the ceiling wall 4. The oil adhering to each wall surface flows and flows, especially the oil flowing along the side wall 9 and bottom wall 6, which tends to accumulate at the position 8 where the direction changes, but since the hole 11 is drilled in this part,
Oil flows into this hole 11. The oil that has flowed into the hole 11 flows into the hollow shaft 13, and from inside this shaft 13 flows into the narrow hole 15.
The lubricant is supplied to the bearing portion of the torque transmission gear 14 on the outer periphery of the torque shaft 13 through the shaft to ensure lubrication.
