(In this case, the tension member and the pressing member are connected to one another in the longitudinal direction of the chain 2 with the axis of each root part (long and short parts extending inward). The pressing member is configured as an arm, and the pressing member is pressed and tilted inward by a spring, and the tip of the pressing member is brought into contact with the rear surface of the tip of the member that applies the pressure.

According to the present invention, the scissor-densing member (5) and the suppressing member (6) are attached to one side and the other side of the mengcheng (2) in the longitudinal direction. !Axle of body (5m) (4a

Initially, the pressing members (6) are approximately parallel to each other as shown in the first figure, but considering the extension of the pressing member (2),
For example, as shown in the drawing, the test pressing member (6) is largely tilted in a substantially perpendicular direction to the scissor-densifying member (5), and the spring (7) is, for example, a coil spring; This is because the spring is rarely strengthened gradually by tilting the member (6), but in this case, the member (6) gradually changes its point of action from point 1 to point 1 with respect to the member (51 &). Thus, due to this principle, the member (5) is always kept at a substantially constant pressing force.

る。5 As described above, according to the present invention, the tensioning member and the pressing member are formed into one and the other longitudinal arms of the chino (long arms having 41 roots and extending inward from each other). As a whole, the pressure member is relatively compact and can be easily installed, and furthermore, by tilting inward, the pressing member can press the tip of the pressing member intermittently against the tension member. Even if the spring strength decreases, it is compressed and has the rumored effect of always maintaining a constant pressing force.
