LID BODY LOCKING APPARATUS OF RAILCAR

摘要

A locking apparatus includes a shaft member having an operating shaft of a non-circular shape in cross section, and a body member including a bearing part and a cylindrical part. A cover member of a ring shape is fixed to the inner circumferential surface of the cylindrical part, at a position corresponding to a tip end of the operating shaft, and a movable member is slidably fitted onto the operating shaft. The movable member is configured so that it is located at a normal position where the movable member fills a clearance between the operating shaft and the cover member when a latch member engages with the car body, and the movable member is maintained at a retreated position that is retreated from the normal position when the movable member is plunged, the operating shaft is rotated, and the engagement between the latch member and the car body is released.

主权项

1. A lid body locking apparatus of a railcar, for locking a lid body, that opens and closes an opening formed in a car body of the railcar, to the car body in a state where the lid body closes the opening, the apparatus comprising:
a shaft member having one end portion formed with an operating shaft of a non-circular shape in cross section and the other end portion fixed to a latch member that engages with the car body; a body member penetrating the lid body, and including a bearing part for rotatably supporting an intermediate part of the shaft member and a cylindrical part for accommodating the operating shaft; a cover member of a ring shape, fixed to an inner circumferential surface of the cylindrical part at a position corresponding to the tip end of the operating shaft, and defining a clearance around the operating shaft; and a movable member slidably fitted onto the operating shaft, wherein the movable member is configured to be located at a normal position where it fills the clearance between the operating shaft and the cover member when the latch member engages with the car body, and wherein the movable member is configured to be maintained at a retreated position that is retreated from the normal position when the engagement between the latch member and the car body is released by pushing into the movable member and rotating the operating shaft.
