That is, a tappet, a push rod 8 and a knuckle type arm 11 are attached to the valve cam of the forced air cooling type overhead valve engine E.
Through, the intake and exhaust valve 20 is interlockingly connected so that it can be driven to open and close,
The stud bolt 1 is attached to the cylinder head 2 of this engine E.
6, the spherical bearing 18 is supported, and the spherical bearing portion 12 of the knuckle type swing arm 11 is pivotally supported by the spherical bearing 18 so that the push rod contact portion 13 of the knuckle type swing arm 11 is supported. In addition to receiving the push rod tip portion 8a, the valve shaft head contact portion 14 is contacted with the valve shaft head 21a of the intake / exhaust valve 20.

る。The above-mentioned conventional techniques have the following problems. I. Since the push rod 8 is in sliding contact with the guide hole 30a of the push rod guide plate 30, the guide hole 30a becomes large due to wear, and the swing of the knuckle type arm 11 increases as the wear progresses. B. Since the push rod guide plate 30 is required and the number of parts is increased and the labor for assembling is required, the manufacturing cost is high. An object of the present invention is to solve the problem of wear of the guide hole 30a of the push rod guide plate 30 and to reduce the manufacturing cost by omitting the push rod guide plate.

要旨とするものである。The means adopted by the present invention to achieve the above object is, for example, as shown in FIGS. 1 and 2, in the basic structure, the knuckle type arm 11 described above.
A valve shaft head engaging portion 15 is formed on the valve shaft head abutting portion 14, and the valve shaft head engaging portion 15 is engaged with the valve shaft head 21a of the intake / exhaust valve 20 in a roll-proof manner. This is the summary.

に解消する。The present invention operates as follows. The push rod 8 moves up and down by the valve cam 6, and the knuckle type swing arm 11 swings back and forth with the spherical bearing 18 as a swing fulcrum.
The valve shaft head abutment portion 14 contacts the valve shaft head 21a and moves it up and down to open and close the intake and exhaust valve 20. At this time, the knuckle type arm 11 has its valve shaft head engaging portion 15 engaged with the valve shaft head 21a in a roll-proof manner, and is restrained by the motion of the valve shaft head 21a without lateral vibration. Since it swings back and forth, the knuckle type swing arm 9 does not swing left and right. Further, since the valve shaft head 21a rarely comes into sliding contact with the valve shaft head engaging portion 15, the problem of wear is substantially eliminated.

It is possible to solve the problem of wear of the push rod guide hole and prevent the swing of the knuckle type swing arm 11 from increasing for a long period of time. Further, the valve shaft head engaging portion 15 has the knuckle type arm 11
Since it is integrally formed with the push rod guide plate 30, which is an independent component, the structure thereof is simplified, and the manufacturing cost can be reduced by omitting the assembling work.

製造コストを引き下げることができる。With the construction of the above-mentioned swing arm knuckle support type valve operating device 10, the knuckle type swing arm 11 swings back and forth with the spherical bearing 18 as a fulcrum based on the vertical movement of the push rod 8, and the valve shaft head contact portion. 14 moves the valve shaft head 21a up and down to open and close the intake and exhaust valve 20. At this time, the knuckle-type swing arm 11 swings back and forth with the valve shaft head engaging portion 15 engaged with the valve shaft head 21a in a rolling prevention manner, so that the knuckle-type swing arm 11 cannot swing to the left and right. Absent.
Further, since the valve shaft head 21a rarely comes into sliding contact with the valve shaft head engaging portion 15, the problem of wear is substantially eliminated. This solves the problem of wear of the push rod guide hole and prevents the knuckle type arm from swinging significantly. Further, since the conventional push rod guide plate can be omitted, the structure is simplified, and the labor for assembling can be omitted, and the manufacturing cost can be reduced.
