Then, when the suction by the cleaner is stopped, the check valve 60 is displaced toward the position indicated by the solid line in FIG. 6, that is, the closed position where the suction portion 30c is closed by contacting the shape retaining portion 40.

  As described above, according to the plate-like member 21 of the present embodiment, the air flow from the outside of the cylindrical body 30 formed by joining the pair of joining end portions 31a, 31a in the base 31 into the suction pipe P. The first hole 30s having a shape capable of securing the air flow, and the air flow extending from the outside of the cylindrical body 30 into the suction pipe P is provided on the suction portion 30c side of the first hole 30s. The suction tool 10 having the second hole 30t having a shape capable of being formed is formed. Therefore, when the suction pipe P is connected to the suction tool 10 between the end of the cylindrical body 30 on the connection part 30b side and the first hole 30s, the suction pipe P is formed near the tip of the suction pipe P. Since the air flow from the outside of the cylindrical body 30 to the inside of the suction pipe P is secured through the first hole 30s, the occurrence of a problem that the suction tool 10 is crushed due to the negative pressure inside the cylindrical body 30 is suppressed. Is done. When the suction pipe P is connected to the suction tool 10 between the first hole 30s and the second hole 30t in the cylindrical body 30, the second is formed near the tip of the suction pipe P. Since the air flow from the outside of the cylindrical body 30 into the suction pipe P is secured through the hole 30t, the occurrence of a problem that the suction tool 10 is crushed due to the negative pressure inside the cylindrical body 30 is suppressed.

  Further, in the suction tool forming member 11 of the present embodiment, the suction tool 10 including the collection tool 70 is formed by joining the pair of joint end portions 31 a and 31 a in the base 31. Since the first joining region 31v in the suction tool 10 is formed between the suction part 30c and the second hole 30t, the suction object once sucked in is spilled out of the suction tool 10 from the second hole 30t. Can be prevented. Furthermore, since this suction tool 10 has the 2nd junction area | region 31w of the shape extended toward the connection part 30b side from the 1st junction area | region 31v avoiding the 2nd hole 30t, the internal peripheral surface of the cylindrical body 30 In addition, a joint portion between the tubular body 30 and the collecting tool 70 is effectively ensured, and the separation of the collecting tool 70 from the tubular body 30 can be suppressed.

  Further, according to the plate-like member 21 of the present embodiment, when the cylindrical body 30 is formed by joining the pair of joining end portions 31a and 31a, the shape retaining portion forming piece 41 is formed into a cylinder by the bending guide portion 41a. The suction tool 10 having the shape retaining portion 40 that increases the rigidity of the tubular body 30 so as to keep the shape of the tubular body 30 can be formed by a simple operation of bending the inside of the tubular body 30. Here, since the shape retaining portion 40 is formed by bending the shape retaining portion forming piece 41 with the bending guide portion 41a having a shape convex toward the connection portion forming portion 31b, the shape retaining portion 40 is connected to the connection portion from the suction portion 30c. The shape is inclined so as to rise toward 30b. The shape-retaining portion 40 has this shape, and when it is bent at the boundary portion with the base so as not to rise so as to rise from the suction portion 30c toward the connection portion 30b, that is, a base that becomes a bent portion. The boundary portion of the cylindrical body 30 is bent so that the inner peripheral surface of the cylindrical body 30 and the surface of the shape retaining portion 40 on the inner peripheral surface side of the cylindrical body 30 are in contact with each other over substantially the entire surface. Compared to the case, since the rigidity of the cylindrical body 30 can be increased and the external force that deforms the suction portion 30c can be resisted, the cylindrical body 30 can maintain the shape of the suction portion 30c. Therefore, according to the plate-shaped member 21 of this embodiment, the suction tool 10 which can suppress the deformation | transformation of the suction part 30c at the time of use and can perform a cleaning operation | work efficiently can be formed.

  Further, the plate-like member 21 of the present embodiment has an external force applied to the tubular body 30 such that the suction portion 30c is deformed in a state where the tubular body 30 is formed by joining the pair of joining end portions 31a and 31a. Even if it acts, since the contact part 40c of the shape retaining part 40 contacts the inner peripheral surface of the cylindrical body 30 and resists the external force, the deformation of the suction part 30c is further suppressed.

  Further, the plate-like member 21 of the present embodiment is formed by the suction tool 10 having the standing restriction portions 50 and 50 by a simple operation of bending the standing restriction portion forming pieces 51 and 51 inward at the boundary portion with the base 31. Is done. As a result, even if an external force that causes the shape retaining portion 40 to stand up from an inclined state acts on the shape retaining portion 40, the standing restriction portions 50, 50 regulate the standing shape retaining portion 40, so the shape retaining portion 40 tilted states are maintained. Accordingly, the shape retaining portion 40 increases the rigidity of the cylindrical body 30 and suppresses deformation of the suction portion 30c.

  Further, the plate-like member 21 of the present embodiment is formed by bending the shape retaining portion forming piece 41 and the standing restricting portion forming pieces 51 and 51 at the boundary portions with the base 31 to form the shape retaining portion 40 and the standing restricting portions 50 and 50, respectively. When formed, the shape retaining portion 40 and the upright restricting portions 50, 50 engage with each other so as to restrain each other, so that both effectively restrict each other's displacement and maintain each other's bent state. Specifically, the first overlapping portions 50b and 50b of the standing restriction portions 50 and 50 overlap the surface of the shape retaining portion 40 on the side close to the inner peripheral surface of the cylindrical body 30, and the second overlapping portions 50c and 50c. Is overlapped with the surface on the opposite side to the surface near the inner peripheral surface of the cylindrical body 30 in the shape retaining portion 40, so that the shape retaining portion 40 and the upright restricting portions 50, 50 are partially alternate. It overlaps with each other and becomes a relationship of restraining each other.

  Further, the plate-like member 21 of the present embodiment has the cylindrical body in a state where the suction portion 30c of the cylindrical body 30 formed by joining the pair of joining end portions 31a and 31a is in contact with the floor surface. 30 will be inclined. Therefore, when the operation of the vacuum cleaner is stopped, the sucked inhaled material falls along the inner surface of the lower portion of the inclined cylindrical body 30 toward the suction portion 30c. Here, since the shape retaining portion 40 is provided so as to extend from the end portion on the suction portion 30c side of the cylindrical body 30 in the inclined posture, the cylinder in the inclined posture when the operation of the cleaner is stopped. The suction object that has fallen along the inner surface of the lower portion of the cylindrical body 30 is inclined so as to rise from the suction section 30c toward the connection section 30b, and the inner peripheral surface of the cylindrical body 30. And being out of the suction tool 10 is suppressed.

  Further, the plate-like member 21 of the present embodiment is a simple operation in which the check valve forming piece 61 is bent inward at the boundary portion with the base 31, and the allowable position and the closed position with the check valve bent portion 60a as a fulcrum. The suction tool 10 having the check valve 60 movable between the two can be formed.

  Further, the plate-like member 21 of the present embodiment is configured such that the check valve 60 and the shape retaining portion 40 when the check valve 60 is formed by bending at the boundary with the base 31 are the suction port of the suction portion 30c. Can be blocked. Therefore, according to this plate-shaped member 21, it is possible to form the suction tool 10 in which the sucked material once sucked is suppressed from coming out of the suction tool 10.

  Moreover, the suction tool component member of the present embodiment includes a first state in which the cylindrical body 30 is flattened, and a second state in which a predetermined space is formed inside the cylindrical body 30 and can be used as the suction tool 10. Since it can be switched between states, the form can be changed according to the situation, such as the first state during storage and transportation, and the second state during use.

  Furthermore, this suction tool component member has an intermediate position between the first ridge line 30h and the second ridge line 30j at the end on the connection part 30b side of the tubular body 30 when the tubular body 30 is in the second state. The included portion has a first planar portion 30n whose outer shape is substantially planar. Specifically, the suction tool constituting member includes at least one of the first ridge line 30h and the second ridge line 30j at the end on the connection part 30b side, and the first ridge line 30h and the second ridge line 30j at the end. Since there is a pair of cut portions 30m, 30m having a shape extending toward the suction portion 30c from positions separated from each other so as to sandwich the intermediate position between them, the external force applied to each ridge line when the second state is established The cylindrical body 30 when it is blocked by the notches 30m, 30m and is not transmitted to the intermediate position of each ridge line at the end on the connection portion 30b side, and thereby the suction component member is in the second state. The outer shape of the portion sandwiched between the pair of cut portions 30m and 30m at the end portion on the connection portion 30b side is kept substantially flat. Therefore, it is possible to suppress the angle formed by the intermediate position of each ridge line on the outer peripheral surface of the cylindrical body 30 from being reduced, or the occurrence of folding at this portion.

  Moreover, the suction tool 10 of this embodiment is cylindrical, when the part pinched by a pair of notch parts 30m and 30m in the cylindrical body 30 and the curved part of the suction part 30c cooperate. Of the outer peripheral surface of the body 30, the side on which the pair of cut portions 30m, 30m is formed can be easily maintained in a curved shape. As a result, when the suction tool 10 is connected to the suction pipe P, the curved portion of the outer shape of the cylindrical body 30 and the inner peripheral surface of the tip of the suction pipe P come into line contact. And the contact location of both is fully ensured and omission from the suction pipe P of the suction tool 10 can be suppressed.

  Further, the suction tool 10 of the present embodiment has a pair of cuts at a position that equally divides the space between the first ridge line 30h and the second ridge line 30j at the end of the outer peripheral surface of the cylindrical body 30 on the connection portion 30b side. Since the cut-in portions 30m and 30m are formed, the outer shape on the side where the pair of cut-out portions 30m and 30m are formed in the end portion of the outer peripheral surface of the cylindrical body 30 on the connection portion 30b side becomes close to an arc shape. Thus, the side on which the pair of cut portions 30m and 30m are formed on the outer peripheral surface of the cylindrical body 30 is easily kept in a curved shape.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is shown not by the above description of the embodiments but by the scope of claims for patent, and further includes meanings equivalent to the scope of claims for patent and all modifications within the scope.

  For example, in the above embodiment, the cylindrical body 30 is formed with two holes spaced apart from each other in the axial direction from the connecting portion 30b to the suction portion 30c, that is, the first hole 30s and the second hole 30t. Although shown, the cylindrical body 30 may be formed with three or more holes spaced apart from each other in the axial direction. Moreover, you may provide the slit of the shape extended along the direction which connects the connection part 30b and the suction part 30c so that these each hole may be connected.
