The sinking aid also includes: a stretch presser member 20 for generating downward pressure when a halfway part 21a of the horizontally stretched rubber ring 21 is brought up; and pressure contact member 30 with one end 30a abutting on the cloth 15 to press the cloth from above so that the cloth 15 sinks, and which is formed in a strip shape made of a plastic material to be used in a raised attitude. The pressure contact member has a slit part 31 cut in the direction orthogonally crossing the longitudinal direction halfway in the longitudinal direction so that the rubber ring 21 of the stretch presser member 20 is caught in the slit part to receive the downward pressure. <P>COPYRIGHT: (C)2011,JPO&INPIT |
