  As shown in FIG. 5, the position adjustment member 33 includes a washer plate 32 and a lock plate 41. The washer plate 32 is made of metal because it needs to have strength, and the lock plate 41 is made of resin because it is necessary to elastically deform the engaging portion 51. The washer plate 32 and the lock plate 41 are integrated by, for example, two caulking shafts 45a and 45b.

  The washer plate 32 is formed by bending a metal plate with a press. The washer plate 32 includes an arm connecting portion 32a that is rotatably connected to the distal end portion of the arm 25 via a bearing, and a flat portion 32b that is bent at a right angle to the arm connecting portion 32a. The flat portion 32b includes a first flat portion 32b1 and a second flat portion 32b2 that is stepped with respect to the first flat portion 32b1. A screw hole 32c that is fastened to the fastening screw 36 is formed in the first flat portion 32b1. Upper and lower two through holes 32d and 32e through which the caulking shafts 45a and 45b are inserted are formed in the second flat portion 32b2. The first flat portion 32b1 and the second flat portion 32b2 are parallel to each other. The size of the step provided between the first flat portion 32 b 1 and the second flat portion 32 b 2 is equal to the thickness of the lock plate 41.

  As shown in FIG. 6, when the washer plate 32 is fastened to the washer body 34 by the fastening screw 36, the first flat portion 32 b 1 of the washer plate 32 comes into contact with the washer body 34, and the second flat portion of the washer plate 32. A lock plate 41 is sandwiched between 32 b 2 and the washer body 34. By forming the first and second flat portions 32b1 and 32b2 on the washer plate 32, the bond between the washer plate 32 and the washer main body 34 can be a high-strength bond between metals, and a resin lock The plate 41 can also be firmly coupled to the washer body 34. Note that the surface of the first flat portion 32b1 may be formed as a flat surface, or may be knurled so that peaks and valleys are alternately formed in the vertical direction.

  FIG. 8 shows a perspective view of the lock plate 41. The lock plate 41 includes an elongated rectangular main body 45, a pair of left and right claw-shaped engaging portions 51 formed on the main body 45, a support portion 46 that connects the engaging portion 51 and the main body 45, And a protrusion 39 formed integrally with the engaging portion between the pair of engaging portions 51.

  As shown in the plan view of FIG. 9, a C-shaped groove 52 is formed at the center of the rectangular main body 45 in the vertical direction. An engagement portion 51, a support portion 46, and a protrusion 39 are formed inside the C-shaped groove 52. The base end of the support portion 46 is coupled to the main body portion 45, and the engagement portion 51 is coupled to the distal end of the support portion 46. The engaging portion 51 is cantilevered by the support portion 46. The rectangular main body 45 is formed with a pair of through-holes 53 through which two caulking shafts pass. A protrusion 39 is coupled between the pair of engaging portions 51. The protrusion 39 is coupled only to the engaging portion 51. The protrusion 39 is erected in the vertical direction from the main body 45. The upper end portion of the protrusion 39 is formed in an inverted L shape so that the area of the portion pressed by the finger is increased.

  As shown in the cross-sectional views of FIGS. 9B and 9C, the engaging portion 51 has, for example, three triangular peak portions 51a, and peak portions 42a and valley portions formed on the side wall 34a of the washer body 34. 42b. Each peak 51a of the engaging portion 51 has a first inclined surface 51a1 and a second inclined surface 51a2. The first inclined surface 51a1 is formed in a straight line, and the internal angle θ1 ′ formed by the first inclined surface 51a1 and the vertical direction (1) is smaller than 90 degrees. The second inclined surface 51a2 is formed in a straight line, and the internal angle formed by the second inclined surface 51a2 and the vertical direction (1) is 90 degrees or more.

  FIG. 6C shows a state where the engaging portion 51 (more precisely, the crest portion 51a of the engaging portion 51) and the trough portion 42b of the washer body 34 are engaged with each other. When the lock plate 41 is moved downward with respect to the washer body 34 from this state, the engaging portion 51 rides on the mountain portion 42a of the washer body 42, and the support portion 46 is elastically deformed and bent. Thereafter, when the engaging portion 51 climbs over the peak portion 42a of the washer body 34, the bent support portion 46 is restored, and the engaging portion 51 is again engaged with the valley portion 42b one step below. For this reason, the engaging portion 51 can be moved downward, and the engaging portion 51 can be positioned. The first inclined surface 42a1 (see FIG. 7 (d)) of the peak portion 42a of the washer body 34 and the first inclined surface 51a1 (see FIG. 9 (d)) of the peak portion 51a of the engaging portion 51 and the vertical direction. Since the inner angles θ1 and θ1 ′ formed with (1) are both smaller than 90 degrees, such a downward movement of the lock plate 41 is possible.

  On the other hand, even if the engagement portion 51 is moved upward from the state where the engagement portion 51 and the valley portion of the washer body 34 are engaged, the state where the engagement portion 51 and the valley portion 42b of the washer body 34 are engaged is maintained. The lock plate cannot be moved upward. This is because the internal angle θ2 ′ formed by the second inclined surface 51a2 (see FIG. 9C) of the peak portion 51a of the engaging portion 51 and the vertical direction (1) is formed to be 90 degrees or more.

  The lock plate 41 including the engaging portion 51 can also move downward with respect to the washer body 34, but cannot move upward. The same applies to the washer plate 32 integrated with the lock plate 41. When it is desired to move the lock plate 41 upward with respect to the washer body 34, the support part 46 is bent by pushing the projection 39, and the engagement part 51 and the valley part 42 b of the washer body 34 are disengaged. Like that.

  Below, the usage method of the washer position adjustment mechanism of this embodiment is demonstrated. FIG. 10 shows a state where the washer plate 32 is not properly positioned with respect to the door 21 and the door 21 is not completely closed. First, the fastening screw 36 (see FIG. 4) is loosened so that the washer plate 32 can move downward relative to the washer body 34. When the door 21 is pushed and the door 21 is completely closed, the washer plate 32 moves downward with respect to the washer body 34. When the washer plate 32 moves downward (1), the distance from the hinge 55 that connects the first door 21a and the second door 21b to the washer plate 32 changes, and the door 21 is completely closed. When the door 21 is completely closed, the washer plate 32 is adjusted to an optimal position in the vertical direction with respect to the washer body 34.

  However, the fastening screw 36 is in a loosened state, and the washer plate 32 is not fixed to the washer body 34. In order to fix the washer plate 32 to the washer body 34 with the fastening screw 36, the door 21 is once opened as shown in FIG. When the door 21 is opened, the arm 25 of the stay 24 generates a biasing force in the direction in which the door 21 is opened. A force for moving the washer plate 32 upward (2) with respect to the washer body 34 is applied. However, the washer plate 32 cannot move upward with respect to the washer body 34. Therefore, the washer plate 32 does not move upward with respect to the washer body 34 to cause positional displacement. Further, since the engaging portion 51 is engaged with the valley portion 42b of the washer main body 34 by using the elastic force of the support portion 46 (see FIG. 6C), the washer plate 32 is lowered with respect to the washer main body 34. It is possible to prevent displacement in the direction. After opening the door 21, when the washer plate 32 is fastened to the washer body 34 with the fastening screw 36, the position adjustment of the washer plate 32 is completed. If the washer plate 32 has moved too much downward with respect to the washer body 34, if the projection 39 is pushed, the engagement between the engaging portion 51 of the lock plate 41 and the valley portion 42 b of the washer body 34 is released. The washer plate 32 can be moved upward with respect to the washer body 34.

  The present invention is not limited to the embodiment described above, and can be implemented in various embodiments without departing from the scope of the present invention.

  In the said embodiment, although the washer position adjustment mechanism of this invention is provided in the folding door, if it is necessary to adjust the position of a washer with respect to a door, it can be used for doors other than a folding door.

  In the above-described embodiment, the washer main body is provided with a crest and a trough, and the lock plate constituting the position adjustment member is provided with the engagement, but the washer main body is provided with a crest and a trough on the lock plate. A part can also be provided.

  In the above embodiment, the lock plate cannot be moved upward with respect to the washer body. However, the lock plate can be moved upward. When the biasing force in the direction of opening the door is applied from the arm of the stay, it is sufficient that the lock plate is not movable upward with respect to the washer body.

  The internal angle θ2 ′ formed by the second inclined surface of the peak portion of the engaging portion and the vertical direction may be 90 degrees or less. In this case, the lock plate can move upward with respect to the washer body. However, if the holding force that prevents the lock plate from moving upward with respect to the washer body is larger than the urging force in the direction of opening the stay door, the position shift occurs in the state shown in FIG. There is no danger of causing.

  In the above embodiment, the engaging portion is cantilevered by the support portion. However, the engaging portion may be supported by the support portion as long as the support portion can be bent.

  In the above embodiment, the engaging portion is meshed with the trough using the elastic force when the supporting portion that cantilever-supports the engaging portion is bent, but as shown in FIG. The engaging portion 62 can be engaged with the trough portion 42b using the elastic force when the coil spring 61 is compressed. In this example, the engaging portion 62 is formed in a cylindrical shape whose tip is rounded into a spherical shape. The coil spring 61 is accommodated in a cylindrical recess 63 formed in the lock plate 41. In addition, a leaf spring may be used as the support portion instead of the coil spring, and the leaf spring may be integrated with the engaging portion 62.
