Abstract
An opening and closing device 10 for a fallboard 8 includes a first damper member 13 that dampens the rotational movement of the fallboard 8 by constantly applying a fixed load to the fallboard 8, and a second damper member 14 that dampens the rotational movement of the fallboard 8 by applying a load to the fallboard 8 depending on a closing movement or an opening movement of the fallboard 8. Accordingly, when the fallboard 8 is being closed, the closing movement of the fallboard 8 can be slowed by being dampened by the first damper member 13 and the second damper member 14, and when the fallboard 8 is being opened, the opening movement of the fallboard 8 can be slowed by being dampened by the first damper member 13 and the second damper member 14.
