The purpose of the present invention is to shorten the operation time for an upper pulley of a speed regulation unit. The protective cover is fixed to the bottom surface of the machine chamber so that the upper pulley of the speed regulation unit is accommodated in the protective space. A side wall plate of the cover body is provided with a first opening, and the first opening can be closed by the inspection door. Therefore, when the upper pulley is operated, the upper pulley can be operated from the first opening. Therefore, the operation time of the upper pulley of the speed regulation unit can be shortened.

    本发明的目的在于实现缩短对于调速单元的上部滑轮的作业时间。保护罩以使调速单元的上部滑轮收纳在保护空间中的方式固定在机械室的底面上。在罩本体的侧壁板设置有第一开口,能够由检查门关闭第一开口。由此,在对上部滑轮进行作业时,能够从第一开口对上部滑轮进行作业。因此,能够实现缩短对于调速单元的上部滑轮的作业的时间。
