As a result, the guide rod 25 can move together with the turning sprocket 14. The guide rod 25 can stabilize the adjusting block 22 and prevent the flat wire spring 23 from being improperly detached. Although the number of the flat wire spring 23 and the guide rod 25 in the present embodiment is plural, the flat wire spring 23 and the guide rod 25 may be arranged one-to-one, if necessary.

The above-mentioned chain tension adjusting mechanism 20 is arranged between the pedestal 10 and the turning sprocket 14, and the marching chain 18 receives tension or pushing force on a part of the chain segment with the turning sprocket 14 as a boundary. When structural vibration occurs, the turning sprocket 14 can move with respect to the fixed block 11 locked to the pedestal 10, and a plurality of flat wire springs 23 are arranged between the turning sprocket 14 and the fixed block 11. Therefore, when each vibration (that is, external force) generated by the marching chain 18 acts on the turning sprocket 14, the plurality of flat wire springs 23 are deformed to generate mechanical potential energy (potential energy). When it is absorbed and accumulated and the external force is removed, the accumulated mechanical potential energy is released and returns to the initial shape. Repeatedly in this way, it helps to march the chain 18 smoothly, can effectively maintain the tension balance of the chain 18, and improves the click phenomenon due to the uneven tension of the chain of the existing chain type blade magazine. Therefore, the service life of the chain can be effectively extended. Further, as shown in FIGS. 6 and 7, according to the present embodiment, the screw 21 is screwed in and out of the fixed block 11 from the adjusting block 22 to the contact portion 14b of the turning sprocket 14.
