摘要： PROBLEM TO BE SOLVED: To provide a roller skate link having a floor plate structure which has a little heat effect and develops a little welding strain, flexure, etc., caused by the welding. SOLUTION: One part side of the floor plate constituting piece is disposed on a joist 1 and the side surface lower part of this floor plate constituting piece is combined to the joist 1 with a fillet-welding and also, the side surface lower part faced to the other part side of the floor plate constituting piece is formed by cutting off. The mutual side surfaces of both floor plate constituting pieces at the one part side and the other part side, are butted and disposed so as to bring into contact with mutual side surfaces, and the mutual floor plate constituting pieces at the one part side and the other part side are combined with a partial fusing welding welded from the upper surface.

摘要： PURPOSE: To facilitate easy conduction of operations to house or take out or move course ropes by providing course rope equipment with a water feed device for supplying water to the course rope equipment and a discharge device for discharging the water out of the course rope equipment. CONSTITUTION: This course rope housing equipment 7 formed as a watertight blind groove of nearly the same length as the length of the course rope 4 along a course direction is installed in the lower part of a side deck 6 existing on the outer side of an overflow groove 5. The course rope housing equipment 7 is provided with the water feed device 8 for supplying the water to the housing equipment 7 and the draining device 9 for discharging the water supplied and stored by the water feed device 8 out of the housing equipment 7. The outlet and inlet port 10 of the course rope 4 in the aperture in the upper part of the housing equipment 7 is provided with a covering cap 11. The water is supplied by the water feed device 8 into the housing equipment 7 to raise the water level up near to the side deck 6 to move the course ropes 4 and to house the course ropes in the housing equipment 7 while floating the course ropes on the water surface in the state of holding the course ropes extended.
