However, in the case where the scaffold is assembled in this way and the worker rides on the scaffold to perform the work, the worker goes up and down on the scaffold every time the work content changes. Not only does it have to be moved, which is very labor-intensive and time-consuming, but the work of incomplete scaffolding at high altitudes in modern high-rise buildings keeps workers safe. It is difficult and there is a problem that the degree of fatigue of the operator is large.

Therefore, in order to solve the above-mentioned problem, a hoistway working device in which a hoisting work frame is arranged in the hoistway has been proposed (Japanese Patent Laid-Open No. 58-193876).

However, there is a problem that the effect of conversion is not improved. In addition, it is necessary to move the fixed arm with respect to the wall surface of the entire apparatus to horizontally perform centering within a unit of several millimeters, and there is a problem that it is extremely difficult to actually perform the centering reliably.

In view of the above points, an object of the present invention is to provide a hoistway working device having high accuracy, good workability, and high applicability.
