To provide a casing structure of an electric point machine having higher water resistance than a conventional technology.SOLUTION: A casing structure of an electric point machine 1 includes a case (a casing) 10 having an opening part 10a on its top surface, a case cover (a lid body) 11 opening/closing the opening part 10a, and a frame-like seal member 12 formed by a flexible elastic material to surround the opening part 10a. The seal member 12 includes a plurality of upward facing protrusion parts, which are mounted on an upper part of the case 10 to protrude upward and are arranged in parallel to extend over its entire circumference, on its upper part. When the opening part 10a is closed with the case cover 11, at least one of the plurality of upward facing protrusion parts is pressed with the case cover 11.SELECTED DRAWING: Figure 1

    【課題】従来技術に比べて高い耐水性を有する電気転てつ機の筐体構造を提供する。【解決手段】電気転てつ機1の筐体構造は、上面に開口部10aを有するケース(筐体)10と、開口部10aを開閉するケースカバー(蓋体)11と、柔軟な弾性材料で形成されて開口部10aを囲む枠状のシール部材12とを含む。シール部材12は、ケース10の上部に取り付けられ、及び、上方に突出すると共に全周にわたって延びる並列した複数の上向突条部を上部に有し、ケースカバー11による開口部10aの閉塞時に複数の上向突条部の少なくとも一つがケースカバー11によって押圧される。【選択図】図1
