At least one of the first and second pivot sections includes: a damper mechanism provided on one of the side board and an end portion of the fallboard and having a driven member to receive pivotal movement; and a driving member engageable with the driven member and operable in interlocked relation to the other thereof. The damper mechanism generates a load against pivotal force from the driven member. At least one of the first and second pivot sections includes: a pivoting member pivotally supported on one of the side board and the end portion of the fallboard; and a retainer fixed to the other thereof to position and retain the pivoting member at a predetermined position.
