Description

  The present invention relates to an end plate for a joint plate used for a floor joint plate for closing a joint portion.

  Conventionally, as an end plate for a joint plate used for a floor joint plate that closes the joint portion between the casings, the joint plate slide support recess and the tip end are supported so as to cover the joint plate slide support recess and the rear end A tip portion that can slide and move on the one floor frame is vertically moved to a tip portion of a floor joint plate that is attached via a fixture so that the tip portion can rotate upward to the other floor case. A cover plate "(Patent Document 1) attached so as to be rotatable is known.

  Such a joint plate end plate (cover plate) may be a plate having an anti-slip projection such as a striped steel plate on the upper surface, but such a projection is not suitable for a tire of a light vehicle. The effect of preventing slipping could not be expected, and slipping of various vehicles could not be prevented.

  In addition, even if a groove or the like is to be formed on the upper surface of the end plate for the joint plate, the end plate for such a joint plate has a drawback that the workability is poor because stainless steel is used in consideration of rust prevention and the like. It was.

  If aluminum is used, rust prevention and workability will be good, but aluminum has a very small elastic limit and has the disadvantage that plastic deformation occurs when a vehicle or the like gets on (no springback occurs). .
