Claims

[Scope of Claim for Utility Model Registration] 1. A breather device 13 is formed in the head cover 3 of the overhead valve engine E at a position biased to either side when viewed from the pair of front and rear rocker arms 11, and a push rod insertion hole 6 and a rocker arm are formed in the crank chamber 5. In a breather device for an overhead valve engine configured by communicating a breather device 13 through the chambers 4 in order, the breather device 13 is arranged on one side of the front and back inside the rocker arm chamber 4, and the breather device 13 is arranged along the side wall of the rocker arm side of the rocker arm chamber 4. The blow-by gas flowing into the rocker arm chamber 4 is directed to the breather device 1 from the side opposite to the rocker arm installation side.
3. A breather device for an overhead valve engine, characterized in that the breather device is configured to flow into the engine. 2. A breather device 13 is formed in the head cover 3 of the overhead valve engine E at a position that is biased to either side when viewed from the pair of front and rear rocker arms 11, and the breather device 13 is inserted into the crank chamber 5 through the push rod insertion hole 6 and the rocker arm chamber 4 in this order. In the breather device for an overhead valve engine configured by communicating the breather device 13 with the rocker arm chamber 4, the breather device 13 is arranged on one front and rear side of the rocker arm chamber 4, and the communication port 14 that communicates the breather device 13 with the rocker arm chamber 4 is covered with a communication port cover. 17, and the opening 16 of this communication port cover 17
is formed on the anti-push rod installation side,
The bottom wall 18 of the communication port cover 17 is formed into an inclined wall that is higher on the side where the push rod is disposed, so that the blow-by gas flowing into the rocker arm chamber 4 flows into the breather device 13 from the side opposite to the side where the rocker arm is disposed. A breather device for an overhead valve engine featuring: 3. A breather device 13 is formed in the head cover 3 of the overhead valve engine E at a position that is biased to either side when viewed from the pair of front and rear rocker arms 11, and the breather device 13 is inserted into the crank chamber 5 through the push rod insertion hole 6 and the rocker arm chamber 4 in this order. In the breather device for an overhead valve engine, the breather device 13 is arranged in the rocker arm chamber 4 on the side opposite to the push rod, and the blow-by gas flowing into the rocker arm chamber 4 is made to cross the rocker arm chamber 4. A breather device for an overhead valve engine, characterized in that it is configured as follows.
