<p>PROBLEM TO BE SOLVED: To provide a fastening device capable of making a work for storing twist-lock at a use position simple.SOLUTION: A position of an inclined rotation axis 151 of a twist-lock 52 is designed at a position where the twist-lock 52 standing at a use position is inclined toward a storage position due to the self-weight of the twist-lock 52. When the twist-lock 52 at the use position is turned down to be set at the storage position, an operator operates a lock cover operation lever 141 so that a lock cover 55 at a closed position is inclined to an opening position. At that time, the twist-lock 52 at the use position tries to turn down to the storage position due to its self-weight. Thereby, the vertical positions of the twist-lock 52 at the use position and the lock cover 55 which tries to stand from the closed position to the opening position are switched, resulting in that the twist-lock 52 turns down to the storage position due to its self-weight.</p> |
