要約
(EN)

A bush attached to a through hole of a casing of a motor holds a conductor. The bush includes a main body, an insertion hole, a flange, and a rib. The main body includes a first end surface, a second end surface facing the first end surface in a first direction, and side surfaces between the first end surface and the second end surface. The insertion hole penetrates an inside of the main body in the first direction, and allows the conductor to pass through. The flange protrudes from a side surface in a direction perpendicular or substantially perpendicular to the first direction. The rib protrudes from the side surface in a direction perpendicular or substantially perpendicular to the first direction.
