  • Patent number: 11355994
    Abstract: 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.

  • Patent number: 10370038
    Abstract: Contemplated are cost reduction and enhanced readiness of parts management related to right and left fenders. A work vehicle includes right and left fenders (16) each having a vertical plate member (18) covering an inner face of a traveling device from an inner side of a vehicle body and a top plate member (19) covering an upper portion of the traveling device (5) from above, wherein the top plate member (19) is configured to be front-rear symmetric, and each of the vertical plate member (18) and the top plate member (19) is configured to act as a right-left interchangeable member.

  • Patent number: 9484058
    Abstract: {circle around (1)} A spindle motor includes a fixing portion defined by a bearing portion, a holder portion, a gap between the bearing portion and the holder portion, and an adhesive arranged in the gap. {circle around (2)} The fixing portion includes first and second protruding surfaces arranged to protrude radially from a first and a second one, respectively, of an outside surface of the bearing portion and an inside surface of the holder portion; and first and second boundary surfaces arranged to join the first and second surfaces, respectively, to the first and second protruding surfaces, respectively. {circle around (3)} At least a portion of the first boundary surface is arranged above the second boundary surface. {circle around (4)} The first and second protruding surfaces are arranged radially opposite to the second and first surfaces, respectively, with a first and a second gap, respectively, intervening therebetween.
