Abstract:
Provided is an engagement chain-type device for operating forward and backward movement, the device being configured so that an increase in the number of parts is minimized, an increase in the size of the device is avoided, the amount of scattering of lubricating oil to the outside of the device is reduced, the wear of connection pins is reduced, the breakage of the connection pins is avoided, and the striking noise and vibration of the chains occurring during the reception of the chains are reduced.
Chain guide plates (130) are respectively provided on both sides of a pair of engagement chains (110, 110) in the chain width direction (W). Chain path restriction members (140, 140) having chain path restriction surfaces (S1, S1) in contact with rigid chain portions (110B, 110B), which are made rigid by engaging and integrating the pair of engagement chains (110, 110) with each other, are disposed so as to be adjacent to the rigid chain portions (110B, 110B).
