Abstract: A pump device includes an electric motor including a motor rotor, a stator including a stator coil, and a rotation shaft, a pump including a pump rotor connected to one axial side of the rotation shaft, and a pump housing that houses the pump rotor, a motor housing that has a bottomed tubular shape with a side portion to which the stator is internally fixed and a bottom portion provided on the other axial side of the rotation shaft, and that houses the motor rotor, a board on which a driver configured to drive the electric motor is mounted, and provided on an outer surface side of the bottom portion of the motor housing, and a busbar that electrically connects the driver and the stator coil, and that is visibly exposed to an outside at least in part when viewed from an outer side of the motor housing.

Abstract: An assembly jig includes an upper jig frame that is provided above a longitudinal outer edge of a large structure, a lower jig frame that is provided below a longitudinal outer edge of the large structure, a connecting jig frame that connects the upper jig frame and the lower jig frame to each other, three supporting parts for supporting the lower jig frame from below, and a jig leg portion that is provided perpendicular to the direction in which the lower jig frame extends and parallel to a ground surface. The supporting parts are provided at three portions that are respectively located under two end portions of the jig leg portion and under the lower jig frame, and arrangement positions of the supporting parts provided at the three portions form a substantially triangular shape when seen from above.
