て固定している。 FIG. 1 is a sectional view showing a conventional general-purpose engine. 2 is a sectional view taken along the - arrow in FIG. 1, and FIG. 3 is a sectional view taken along the - arrow in FIG. In the figure, 1 is a cylinder, which constitutes the engine body, and 2
is a crank chamber that supports the crankshaft 3. The crankshaft 3 is composed of a flywheel-side crankshaft 3a and an output-side crankshaft 3b. Further, the crank chamber 2 is composed of a flywheel side crank chamber 2a and an output side crank chamber 2b. A side cover 4 is fixed to the side of the crank chamber 2 with bolts or the like, and forms a cabana chamber A. Reference numeral 5 denotes a governor device, which is a centrifugal weight type, with a weight 6 that swings in the direction of the arrow due to centrifugal force due to rotation, a weight receiver 7 integrated with the crankshaft 3b, and a weight 6 that swings to the crankshaft. Sliding tube 8 and sliding tube 8 that slide on 3b in the axial direction
The actuating arm 9 swings in the direction of the arrow by sliding in the axial direction of the actuating arm 9, and rotates a cabana actuating shaft 20, which will be described later. 10 is the flywheel, magnetic pole material 1
1 and a wing 12 are integrally formed. Reference numeral 13 denotes an ignition coil, which is attached to a support 14 integral with the crank chamber 2 and has a predetermined distance from the inner circumference of the magnetic pole material 11. 15 is a recoil starter, 16 is a piston, 17 is a spark plug, 18 is a baffle plate, and 19 is a balance weight. 20 is an operating shaft, and the operating arm 9 is fixed by tightening two pan head machine screws 21.
しかし、上記従来のものには次の欠点がある。 However, the conventional method described above has the following drawbacks.
作動腕９と作動軸２０が別体構造の場合、作動
軸２０に少なくとも２個以上のねじ穴加工を行つ

る。この場合、ガバナ室Ａのスペースが制限され
ているため必然的になべ小ねじ２１のサイズも小
さくなり、２個所以上設けることになり、加工、
組立作業が極めて困難となる不具合がある。 When the actuating arm 9 and the actuating shaft 20 are of separate construction, at least two or more screw holes are formed in the actuating shaft 20, and the actuating arm 9 is fixed with a pan head machine screw 21 or the like. In this case, since the space in the governor chamber A is limited, the size of the pan head machine screw 21 will inevitably become smaller, and two or more locations will be required.
There is a problem that makes assembly work extremely difficult.
本考案の目的は上記欠点を排除した調速装置を
提供することであり、その特徴とするところは、

を具えたことである。 The purpose of the present invention is to provide a speed governor that eliminates the above-mentioned drawbacks, and its features are as follows:
The displacement in the coaxial direction of a weight provided on the crankshaft and linked to the same axis is transferred to the operating shaft via a sliding tube and an operating arm whose one end is in contact with the sliding tube and whose other end is fixed to the operating shaft. In a speed governor for a general-purpose internal combustion engine, the operating arm is fixed to the operating shaft at one location, and the operating arm is provided with a threaded joint on both sides of the threaded joint to protrude from the operating arm and come into contact with the operating shaft for positioning. It has two claws.
以下図面を参照して本考案による実施例につき
説明する。 Embodiments of the present invention will be described below with reference to the drawings.
第４図は本考案による１実施例の作動腕と作動
軸を装備した場合の第１図の−矢視断面図、
第５図は第４図の−矢視断面図である。 FIG. 4 is a sectional view taken along the - arrow in FIG. 1 when equipped with an operating arm and an operating shaft according to an embodiment of the present invention;
FIG. 5 is a sectional view taken along the - arrow in FIG. 4.
図において、３ｂは出力側クランク軸である。 In the figure, 3b is the output side crankshaft.

で作動腕３１の作動軸３２への取付けは次のよう
にして行われる。 In the cabana device, when the engine is started and the crankshaft rotates, the centrifugal force causes the weight 6 to swing in the direction of the arrow, causing the sliding tube 8 to slide in the direction of the crankshaft, as shown in FIG. As a result, the actuating arm 31 swings and rotates the actuating shaft 32 to perform speed regulating action. Here, the operation arm 31 is attached to the operation shaft 32 in the following manner.
爪３３を作動軸３２に当接させると共に、なべ
小ねじ３４で作動腕３１を作動軸３２に固定する
ことにより、作動腕３１が第４図において、時計
ならびに反時計方向へ回る動きを阻止でき、なべ
小ねじ３４の１個のみで作動腕３１を作動軸３２
に回り止めをして確実に固定できる。 By bringing the pawl 33 into contact with the operating shaft 32 and fixing the operating arm 31 to the operating shaft 32 with the pan head machine screw 34, the operating arm 31 can be prevented from rotating clockwise or counterclockwise in FIG. , the operating arm 31 is connected to the operating shaft 32 using only one pan head machine screw 34.
Can be securely fixed by preventing rotation.
これにより、ねじ加工工数、組立工数が低減で
きると共に、部品点数も低減される。 As a result, the number of screw processing steps and assembly steps can be reduced, and the number of parts can also be reduced.
