That is, a ventilation hole 3 is provided in each of the two main bodies 1 separated by a certain distance, and the shaft 2 is rotatably inserted through the shaft 2, and as each shaft 2 rotates, the ventilation hole 3 is opened. Each valve 4 is loosely fitted into the inner periphery of the vent hole 3 and fixed to each shaft 2 so as to open and close. Further, each lever 5 is fixed to the outer end 2a of each of the shafts 2 protruding outside the main body 1, and each lever 5 is further connected by a link rod 6, and the actuator rod 7 is connected to both the levers 5, 5. sandwiched between
It is fixed to the intermediate portion of the link rod 6 via a grommet 8. In the conventional shaft connection mechanism having such a configuration, the actuator rod 7 moves due to the action of an actuator (not shown), and this movement is transmitted to the shaft 2 via the link rod 6 and the lever 5, so that the shaft 2 is driven. However, the following problems cannot be avoided. In other words, the valve also has the function of suppressing axial displacement due to shaft rotation, but due to the clearance between the inner diameter of the vent hole in the axial direction provided for opening and closing the valve and the inner diameter of the valve, the shaft rotates as the shaft rotates. There is a risk that the valve may become misaligned in the axial direction, causing the valve to bite the main body.
本考案は上記従来技術における欠点を解消し、
シヤフトの軸方向におけるずれを除去し、バルブ

とするものである。 The present invention eliminates the drawbacks of the above-mentioned conventional technology,
It is an object of the present invention to provide a shaft connection mechanism that eliminates displacement in the axial direction of the shaft and prevents the valve from biting the main body.

が望ましい。 An embodiment of the present invention will be described below with reference to the drawings. FIG. 2 is a partial sectional view showing the shaft coupling mechanism according to the embodiment of the present invention. 9 in the figure is an elastic means attached between the lever 5 and the grommet 8. Figures 3 and 4 show a leaf spring used as a type of elastic means, and Figures 5 and 6 show the leaf spring installed as described above. . Also, Fig. 2 10
is a collar closely interposed between each main body 1 and lever 5 at the outer end of each shaft 2, and its material is preferably resin.

軸方向のずれは弾性手段とカラーによつて抑えら
れ、したがつてバルブが本体をかじることがな
く、しかもアクチユエータロツドも軸方向に定位
置化され、その安定的運動が実現される。 The shaft connection mechanism configured as described above has an elastic means 9 installed between at least one of the levers 5 and the actuator rod 7, and a collar 10 interposed between each main body 1 of the outer end 2a of each shaft 2 and the lever 5. Because of this, it has the following features compared to conventional shaft connection mechanisms. In other words, the axial displacement caused by shaft rotation is suppressed by the elastic means and collar, so the valve does not bite the main body, and the actuator rod is also kept in a fixed position in the axial direction. Stable motion is achieved.
以上説明したとうり、本考案の軸連結機構によ
