で歯飛びや空転の発生を防止する。First, when the drive source 1 is rotated in the normal direction, the transmission body 4 is rotated in the direction shown by the arrow A in FIG. 1, and the load λ3 is rotated in the direction. Looseness occurs between the two. The tensioner 5.6
and an elastic body 7 disposed between these tensioners 5 and 6.
The tensile force of K is applied in the direction of arrow C, thereby preventing tooth skipping between the drive source 1 and the transmission body 4 when the transmission body 4 is a chain, or idling when the transmission body 4 is a belt. To prevent. On the other hand, when the driving source 1 is reversely rotated, the four transmission bodies rotate in the direction of arrow B as shown in FIG.
Looseness occurs between the drive body 1 and the drive body 1. This loosening is absorbed by applying the tensile force of the tensioners 5, 6 and the elastic body 7 disposed between these tensioners 5, 6 in the direction of the arrow. Prevents tooth skipping and idling between the two.

する。(Effects of the Invention) The present invention is constructed and operates as described above, and includes a transmission body that circulates between the drive source 1 and the load 2 and 3 and transmits the power of the drive source 1 to the load 3. Tensioners 5 and 6 are arranged between the slack side and the tension side of 4, respectively, and by connecting the tensioners 6 to these tensioners with an elastic body 7, the load λ3 is brought into pressure contact with the outside of the load λ3. Since the transmitter 4 is designed to absorb the slackness of the transmitter 4,
There is no slack when the drive source 1 rotates in either direction, normal or reverse, and therefore situations such as tooth skipping or idling do not occur between the drive source 1 and the transmission body 4. This has the effect of enabling accurate power transmission.
