Abstract: A linear-motion guiding device is disposed on the wall of the container. The wind turbine includes, at the lower end of the support column, a support-column lower end member capable of being fixed to the linear-motion guiding device. A slider of the linear-motion guiding device is provided with a guide member, and a bolt is inserted through a bolt insertion hole in the support-column lower end member and is screwed into a threaded hole in the guide member. The apparatus includes an attachment guide part including a stepped bolt and a flanged step part, the attachment guide part being configured to guide the support-column lower end member to a position and an attitude in which the bolt insertion hole in the support-column lower end member is aligned with the threaded hole in the guide member when the support-column lower end member is not fixed to the slider.
