Abstract: 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.
