<p><P>PROBLEM TO BE SOLVED: To provide a plate-shaped member for forming a suction tool which can be connected with suction pipes of various diameters, and the inside of which can be restrained from having a negative pressure during use. <P>SOLUTION: The plate-shaped member has a base capable of forming a cylindrical body (30) by bonding a pair of bonding end parts with each other. The base includes: a first hole (30s) having such a shape that an air flow from the outside of the cylindrical body (30) to the inside of a suction pipe can be secured by connecting the outside and inside of the cylindrical body (30) while the cylindrical body (30) and the suction pipe are connected together; and a second hole (30t) provided on the side of a suction portion (30c) relative to the first hole (30s) and having such a shape that the air flow from the outside of the cylindrical body (30) to the inside of the suction pipe, can be secured by connecting the outside and inside of the cylindrical body (30) while the cylindrical body (30) and the suction pipe are connected together. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
