Abstract

PURPOSE:To facilitate the demounting of a distance piece by permitting the distance piece to be divided into plural pieces and demounted from a rudder head and permitting also the coaming on the outer peripheral side of the distance piece to be demounted from the upper surface of a carrier body. CONSTITUTION:The lubricating oil in coamings 6 and 6 is discharged, and a distance piece 4 is divided into plural pieces and demounted from a rudder head 2. If the coaming 6 on the outer peripheral side of the distance piece is demounted from the upper surface of a carrier body 3 and set into pulled-up state, each piece of the divided distance piece 4 can be demounted from the rudder head 2 without being obstructed by the coaming 6. Therefore, the working time can be reduced markedly.
