In the inner side of the head cover upper wall portion 4a, the direction is slightly higher. The center of the longitudinal direction is located at a substantially center and is located at a short position. The movement restricting member 4A is placed at the respective positions of the heads 4, d, and The opposite side, that is, the movement restricting member 4c which becomes the 隹/'-edge is disposed on the side movement restricting member 4d, and the position of the other side-side rocker shaft 7 is sighed on the other side, That is, the exhaust gas is provided on the respective main causes/L, and the movement restricting members 4c are provided in contact with each other, and the direct axes 3 of the I-axis 7 and 7 are swayed, and FIG. 5). The illuminating diagram is provided on the upper members 4c, 4d of the inner surface of the upper wall of the head cover, and in order to suppress the two movements of the arm, the arm shafts 7 and 7 are separately mounted to support the above two glazes 7 7, the respective arm of the rocker arm 7 72 72 is moved to position the mover ^, 7 on the movement, the body part member 4. For example, at the extension of the wide end of the tip end 71 of the rocker arms 71e, 72e The above-mentioned protrusions are opposite to each other (refer to the Η, there is a gap in the material, and the internal combustion engine E of the embodiment of the present invention is supplied to the tender When the burning chamber is fired, the fuel will be combusted and burned by the burning energy:;,,?, the moving movement of the living base P by the connecting rod "吏 crank shaft rotation = 312XP / invention manual (fill Piece) /95-09/95116024 ]5 ' ί3〇7737 = 回转 回转 则 则 则 则 则 则 回转 回转 回转 回转 回转 回转 回转 回转 回转 回转 回转 回转 回转 回转 回转 回转 回转 回转 回转 回转 回转 回转 回转 回转 回转 回转 回转 回转 回转 回转 回转 回转 回转 回转 回转 回转The rotation of the crankshaft]a is determined by the sequence and timing of the rotation of the camshaft 6.

When the internal combustion engine is running, the camshafts are displaced from each other at the cam bulging position, and the axle 6 is misaligned. In the direction of rotation, it is attached to two rocker arms 71, 2, two cams 61, 62, each of which is in contact with the roller, (2), and with the camshaft = J = 71C, ^ the tip of the turn The rocker arm 7 is rotated by the timing of the cams 61, 62, so that the rocker arm 7; : = 1C, 72C is rocked at both the fulcrum and shaken by the other side wrist id Shake 7〗 dl, 72dl and press the valve stem to abut the cake 5] '52 in the order of the order ^ 皮皮仏, 52c' to enter.

In the rocking operation, the movement of the spring force resisting the springs 81, 82 toward the axial direction of the rocker arm shaft 7 can be completely suppressed. Since the embodiment of the present invention has the above configuration, the following effects can be achieved. The head cover 4 is mounted. In the state of the cylinder head 3, there is a limitable anti-312XP/invention specification (supplement)/95-09/95] 16024 • 1307737 repelling arm 71, 7 2 magazine 8], only 9-recognition member 4c, 4d, therefore, the axial movement of the spring force 81:8V of the movement limit of the early force is not necessary to suppress the squat load of the rocker arm 71 when the rocker arm 7 72 is restrained. When the large and small gas turbines are running, the turbulent center < axial movement occurs, and even if it is inside, the vibration can suppress the movement to an appropriate one. In addition, the springs 81 and 82 are appropriately set to the difficulty of the rocker shaft when the pressing load is adjusted by the tappet clearance, and the axial movement of IS] + + Μ , is easy to make during the adjustment. The rocker arms 71 and U f make the adjustment work easy and can improve the 72 private movements; ;:;:r and the movement is also easy, so that the movement can be improved and the workability can be improved. The 71 rocker arms 71, 72 have a movement restricting member 4 which is oriented in the axial direction and protrudes in the radial direction. "Because the contact is large: ^, therefore, it does not hinder the bomb ^ , : The piece 'is easy to make the rocker arms 71, 72 and the search: other so 'to make the rocker arms 71, 72 into and out, structure: 4. , contact, _ becomes substantially no state of the rocker axis 7, 7 ^ 5, _ stability, of course, it can enter the exhaust valve 51, force 5 or so) and close, and can be + 52 The positive opening greatly imparts noise and vibration to the internal combustion engine E, and @# is reduced in the inner surface f of the upper wall portion 4a of the head cover 4.

Therefore, through the rocker arm, it can be added to the movement limiting member 4 The strength burden of the head cover 4 is suppressed to be such that the negative load is dispersed, and the countermeasure for remarkably increasing the strength of the head cover 4 is lowered, and there is no need to have the movement restricting members 4c, 4d formed on the head cover 4 by the front cover. , 1; therefore, the sleeves 7, 7 have recessed recesses 2 and the remaining nails of the rocker shafts 7, 7, the privacy-restricting member shafts 7, 7 and, again, the pots, the cymbals, and the other Close to the rocker arm due to 1 in -§: Exactly restricts the movement of the rocker arms 71, 72.
