The
Thereby, the urging member 90 is disposed on the base plate 20 such that the bent or bent portion 92 protrudes obliquely upward from the mounting surface (surface) of the base plate 20.

First, in a state in which the biasing member 90 is bent or the upper end portion (the far side end portion) of the bent portion 92 is disposed in the biasing member fixing concave portion 70 of the clamping member 50, the clamping member 50 is attached to the base plate 20. On the placement surface side, it is moved in parallel with the center line of the base plate 20 (the center line between the left end edge and the right end edge of the base plate 20) from the near side to the other side.
Then, the first bearing portion 58a and the second bearing portion 58b of the clamping member 50 are inserted obliquely downward from the first opening 26 and moved to the other side, and the upper wall portion 62 and the lower wall portion of the clamping member 12 are moved. 64 is positioned in front of the corresponding first pivot part 24a and second pivot part 24b. Then, the first bearing part 58a and the second bearing part 58b are moved to the movable part 28, and the first bearing part 58a and the second bearing part 58b are moved below the first pivot part 24a and the second pivot part 24b. Move to gap.
The first pivot part 24a and the second pivot part 24b are located between the back end 62a of the upper wall part 62 and the back end 64a of the lower wall part 64 constituting the second opening part 60a and the second opening part 60b. Since it is forcibly fitted through the gap, dropping after the holding member 50 is mounted is restricted.

  In the state where the clamping member 50 is mounted on the base plate 20 in this way, the urging member 90 has its bent or bent portion 92 forcedly displaced away from the initial axial position (see FIG. 8). In other words, it is in a twisted state. Therefore, the clamping member 50 is maintained in a state in which the clamping portion 52 of the clamping member 50 is always in contact with the mounting surface of the base plate 20 due to the restoring force that the biasing member 90 tries to return to the initial unloaded shape. At the same time, the surface of the clamping member 50 is also maintained at a position that is substantially horizontal with the base plate 20.

As shown in FIG. 4, the paper clamp 10 is formed so that the clamping portion 52 of the clamping member 50 is closed with the urging force of the urging member 90 with respect to the base plate 20.
The paper clamp 10 can open the clamping portion 52 of the clamping member 50 against the base plate 20 against the urging force of the urging member 90 by pressing the opening pressing portion 54 of the clamping member 50. .

  In the above-described paper clamp 10, the base plate 20, the clamping member 50, the biasing member 90, and the like have specific shapes. However, in the present invention, they may be formed in other shapes.

  Further, in the above-described paper clamp 10, a torsion spring made of metal is used as a biasing member. However, in the present invention, a spring made of an elastic material such as a synthetic resin may be used, and its shape is also changed. May be.

  Furthermore, the structure of the above-described paper clamp 10 such as the pivot portion 22 for pivotally connecting the base plate 20 and the sandwiching member 50 in the base plate 20 and the sandwiching member 50 may be changed to another structure.
