う。 Generally, as shown in FIG. 6, a centrifugal governor device has a governor shaft 7 supported slidably in the axial direction on the shaft end of an engine rotation shaft 3 such as a crankshaft or a camshaft. The arm portion 10 connected to the governor weight 9 that rotates together with the governor is brought into contact with the side surface of the flange 17 of the governor shaft 7, and the governor weight 9
When the governor weight 9 swings, the governor shaft 7 is brought into contact and shifted, and the outer end of the governor shaft 7 contacts and presses the tip of the governor lever 15. , if the swinging force of the governor weight 9 is applied unevenly to the governor shaft 7,
The governor shaft 7 becomes distorted and the governor characteristics become distorted.

あつた。 In addition, since the tip of the governor shaft 7 and the tip of the governor lever 15 are in contact at one point, and relative rotation occurs at that point of contact, wear is severe here, and this also causes variations in governor characteristics. There were flaws.
この発明は、上記従来構造の欠点を解するため
になされたものであつて、以下にその実施例の詳
細を図面に基づいて説明する。 The present invention has been made to solve the drawbacks of the conventional structure described above, and details of embodiments thereof will be explained below with reference to the drawings.

されている。 A pair of governor weights 9 , 9 are supported by a pin on a bracket 8 fixed to the outer end surface of the gear 4 , and the tip of a bifurcated arm 10 connected from the base of each governor weight 9 is connected to the governor shaft. Relay links 12, 12 made of sheet metal are connected via pins to both ends of an arm portion 11 integrally formed on the distal end side of the arm portion 11, respectively.

で枢支連結されている。 Further, an intermediate member 14 is attached to the outer end of the governor shaft 7 through a bearing 13 so as to be relatively rotatable, and the intermediate member 14 and the governor lever 15 are connected to a pin 16.
It is pivotally connected.

動する。 According to the above configuration, as the crankshaft 3 rotates at high speed, the governor weights 9, 9 centrifugally swing,
The centrifugal force causes the arms 10, 10 and the relay link 1
2 and 12 to the governor shaft 7, and further transmitted to the governor lever 15 via the intermediate member 14. At this time, as the governor lever 15 is pressed and displaced, the pin 16 draws an arcuate trajectory, and the governor shaft 7 swings around the spherical head 6 in response to this.
尚、前記中継リンク１２は第５図に示すように
逆向きに取付けてもよい。 Incidentally, the relay link 12 may be installed in the opposite direction as shown in FIG.
又、前記ガバナ軸７をクランク軸３の孔５に嵌

で枢支連結し実施することもできる。 In addition, the governor shaft 7 is divided into a shaft portion that fits into the hole 5 of the crankshaft 3 and a shaft portion that is pivotally connected to the shaft portion so as to be swingable, and this freely swingable shaft portion and the governor shaft portion are connected to each other. Weight 9 and relay link 12
It is also possible to perform a pivot connection.
以上説明したように、本発明によるガバナ装置

ナ軸がこじれることがなく、長期に亘つてガバナ
特性を高精度に維持できる。 As explained above, the governor device according to the present invention has a spherical head formed at the inner end of the governor shaft, and the spherical head is slidably supported in the hole at the end of the engine rotating shaft. Since the outer end of the governor shaft is configured to be able to swing freely around the center, even if the swinging force of the governor weight is applied unevenly to the governor shaft, the governor shaft will not be twisted, and the governor characteristics will be improved over a long period of time. Accuracy can be maintained.

取付けた中間部材とガバナレバーとを枢支連結し
た構造であつても、ガバナレバーの揺動に対応し
てガバナ軸も球状頭部を中心にして揺動し、両者
の動きがスムーズであり、ガバナ装置としての応
答感度及び精度が高い。 Moreover, even with a structure in which the governor lever is pivotally connected to an intermediate member attached to the outer end of the governor shaft via a bearing, the governor shaft also swings around the spherical head in response to the swing of the governor lever. However, both movements are smooth, and the response sensitivity and precision of the governor device are high.
又、ガバナ軸の外端とガバナレバーとは、ベア
リングを介して相対回動を許し、かつ、枢支連結
