<p>PROBLEM TO BE SOLVED: To facilitate elevating by reducing barrier in operation of an operating portion of an elevator mainly due to gravity by using a characteristic of a matching elastic body. SOLUTION: When the operating portion of the elevator operates ascending operation, a ratio of the operation barrier due to gravity and the like acting in an opposite direction thereto and the elasticity of the elevator acting in a direction reducing the operation barrier is made not to vary beyond a specific range in a necessary operating distance.</p> |
