Description

  The present invention relates to a slider for a slide fastener, which elastically deforms an elastic body arranged on the upper surface of a slider body with a swingable handle.

  As an example of the slider, a slider body including an element passage penetrating in the front-rear direction, an elastic body attached to the upper surface of the slider body, and a handle supported by the slider body so as to be swingable back and forth above the elastic body are provided. Some exist (Patent Documents 1 and 2).

  In the slider described in Patent Document 1, the axis of the handle extends in the left-right direction, but the elastic body extends in the front-rear direction. When the slider is viewed in plan, the front-rear central portion of the elastic body is located directly below the shaft, but the front and rear portions of the elastic body are disposed so as to protrude forward and backward from the shaft. Therefore, the elastic body has a wide portion that is not covered with the shaft (the portion that is visually observed), and has a great influence on the appearance of the slider.

  In the slider described in Patent Document 2, the axis of the handle and the elastic body both extend in the left-right direction. When the slider is viewed in plan, the elastic body is located directly below the shaft over the entire length of the left and right. Therefore, it can be said that the elastic body does not affect the external appearance of the slider of Patent Document 2 compared to the slider of Patent Document 1.

  By the way, the slider of patent document 2 protrudes a pair of support | pillar from the upper surface of a fuselage, and supports the right-and-left end part of an axis | shaft with a pair of support | pillar. In addition, the slider extends in the left-right direction so that the concave portion on the upper surface of the body reaches the opposing surfaces of the pair of support columns. In other words, the left and right ends of the recessed portion are formed in a concave shape on the opposing surface of each column, and the upper side, the front and rear, and the left and right sides of the recessed portion are covered with each column. Yes.

  However, if the left and right end portions of the recessed portion are covered in this way, it becomes difficult to insert the left and right end portions of the handle shaft and the elastic body into the opposing surfaces of the pair of support columns.

  The present invention was created in consideration of the above circumstances, and the purpose of the present invention is to provide a slide fastener slider that makes it easy to attach the shaft of the handle and the elastic body to the upper part of the slider body while using the elastic body extending in the left-right direction. Is to provide.

  The slider for a slide fastener of the present invention includes a slider body, an elastic body, and a handle. The puller is supported by the slider body so as to be able to swing back and forth above the elastic body, a shaft extending left and right, a puller body extending radially outward from the shaft, and a radial direction from the shaft A cam that protrudes outward and elastically deforms the elastic body. The elastic body is attached to the upper surface of the slider body, and the left-right direction is the longitudinal direction. The slider body is provided with an element passage penetrating in the front-rear direction, and an upper wing plate having an elastic body recess for accommodating an elastic body formed on the upper surface thereof and an upper surface of the upper wing plate projecting from the left and right. And a pair of handle attachment columns. The pulling attachment column is a front column and a rear column that are opposed to each other in the front-rear direction, and the front column and the rear column that are close to each other by being plastically deformed so that their upper ends cannot be separated from the left and right ends of the shaft, And a shaft hole penetrating left and right between the rear pillars. The concave portion for elastic body and the elastic body extend left and right until reaching the inside of the pair of shaft holes.

The elastic body recess is formed so as to reach the inside of the pair of shaft holes, that is, between the front column and the rear column. Therefore, the front column and the rear column are arranged through a gap before and after the recess for the elastic body. Also good. However, after the shaft is inserted between the front pillar and the rear pillar, it is desirable to make the front pillar and the rear pillar easier to plastically deform as follows.
That is, the front and back opposing surfaces of the lower ends of the pair of front pillar and rear pillar form part of the front and rear faces of the elastic body recess.

The left and right outer ends of the elastic body recess and the elastic body may be the same as the left and right outer ends of the pair of shaft holes, or may be located inside the left and right outer ends of the pair of shaft holes. In order to facilitate elastic deformation of the body, it is desirable to do the following.
That is, the recess for elastic body and the elastic body are extended to the left and right outer sides than the pair of shaft holes.

As a more specific shape of the recess for the elastic body, there is the following.
That is, the concave portion for the elastic body is provided with a flat portion on which the left and right end portions of the elastic body are placed on the left and right end portions, and a bendable portion that allows the left and right center portions of the elastic body to bend at the left and right center portions.

The left and right end portions of the shaft may be placed so as to overlap the elastic body, but it is desirable to make the elastic body easy to elastically deform as follows.
That is, the upper surface of the upper blade plate is provided with a shaft recess that places the left and right ends of the shaft on the left and right outer sides of the elastic body recess, and the upper surface of the shaft recess is more than the upper surface of the elastic body placed on the elastic body recess. Is also expensive.

The pulling body is placed on the upper surface of the upper wing plate in a lying state. In order to stabilize the pulling body while reducing the height of the pulling body in that state as much as possible, the following is desirable.
That is, the upper surface of the upper wing plate is provided with a pulling recess for placing the pulling body, and the pulling recess is located between the pair of pulling attachment columns in the left-right direction, and in the front-rear direction of the upper surface of the upper wing plate in the front-rear direction. It extends from one end to the other end side, and is positioned below the upper surface of the shaft recess in the vertical direction.

  According to the slider for the slide fastener of the present invention, the pulling attachment column is formed by the front column and the rear column that can be plastically deformed. The elastic body can be placed on the elastic body recess through the left and right side portions of the handle shaft, and the front and rear columns are then plastically deformed, so that assembly is easy.

  Further, if the slider forms a part of the front and rear surfaces of the concave portion for the elastic body by the front and rear facing surfaces of the pair of front pillars and rear pillars, the strength of the front pillars and the rear pillars is weakened. Therefore, it becomes easy to carry out plastic deformation so that the upper part of a front pillar and a back pillar may approach mutually.

  In addition, if the slider extends the concave portion for elastic body and the elastic body to the left and right outside of the pair of shaft holes, the slider is more elastic than the slider for which the horizontal width of the concave portion for elastic body and the elastic body is shorter than that. The lateral width of the body can be increased, and the elastic body is easily elastically deformed.

  If the slider has a flat portion at the left and right ends of the recess for elastic body and a curved portion at the center of the left and right of the recess for elastic body, the left and right ends of the elastic body rest on the plane portion. Is stable and difficult to come off.

  Further, according to the slider provided with the shaft recesses on the upper and lower sides of the upper blade and on the left and right outer sides of the elastic body recesses, the upper surface of the shaft recess is made higher than the upper surface of the elastic body placed on the elastic body recesses. Therefore, the elastic body and the shaft portion do not need to contact each other, the shaft portion does not interfere with the elastic deformation of the elastic body, and the elastic body is easily elastically deformed.

  In addition, according to the slider having the pulling recess for placing the pulling body on the upper surface of the upper blade, the fallen puller can be stably put on the pulling recess, and the pulling force is lowered by the depth of the pulling recess. Can hold.

FIGS. 4A and 4B are a plan view and a cross-sectional view taken along line AA of a slider body used in a second modification of the slider of the first embodiment.

  As shown in FIGS. 1 and 2, the slider S for slide fastener according to the first embodiment of the present invention swings back and forth above the slider body 1, the elastic body 2 attached to the upper surface of the slider body 1, and the elastic body 2. And a handle 3 supported by the slider body 1 so as to be movable. The slider body 1, the elastic body 2, and the handle 3 are not particularly limited in material, but are made of metal as an example.

  Hereinafter, directions will be described with reference to FIG. The front-rear direction is a direction in which the slider body 1 is moved in order to open and close the slide fastener, and is a vertical direction in FIG. The upward direction in FIG. 4 is the front direction and the direction in which the pair of element rows of the slide fastener are engaged. The downward direction in FIG. 4 is the backward direction and the direction in which the pair of element rows are separated. The left-right direction is the left-right direction in FIG. The up and down direction is a direction orthogonal to the paper surface in FIG. 4, the up direction is the front side direction, and the down direction is the back side direction.

  As shown in FIGS. 1, 2, 4, and 5, the handle 3 includes a shaft 31 extending left and right, a pull body 32 extending radially outward from the shaft 31, and a handle extending radially outward from the shaft 31. The cam 33 protrudes in a direction different from the extending direction of the main body 32.

  The handle main body 32 is a portion to be picked by a finger, and has a long and narrow rectangular plate shape having a long side and a short side. The pulling body 32 includes both surfaces 32a and 32b facing the plate thickness direction, and the both surfaces 32a and 32b are surfaces parallel to the left-right direction. When one side 32a of these two sides faces the rear side of the upper surface of the slider body 1 when the handle body 32 is tilted backward, the slider 32 when the other side 32b of both sides falls the handle body 32 forward. It faces the front side of the upper surface of the body 1. As shown in FIGS. 4 and 6, both surfaces 32c and 32c facing the short side of the pull main body 32 are left and right side surfaces, and a portion (corner portion) 32c1 near the both surfaces 32a and 32b facing the thickness direction is a cross-sectional circle. It is a curved surface that swells in an arc. In addition, the left and right side surfaces 32c, 32c of the pulling body 32 have a shape in which the central portion in the thickness direction projects most outward in the left-right direction.

  The shaft 31 has a cylindrical shape, and an intermediate portion in the longitudinal direction (left and right direction) is integrated with the handle main body 32, and both end portions in the longitudinal direction protrude left and right from both side surfaces 32 c and 32 c of the pull handle main body 32. Both ends in the longitudinal direction are rotatably supported by the slider body 1.

  The cam 33 projects radially outward from the longitudinal intermediate portion of the shaft 31 and to the same side as the one surface 32 a in the plate thickness direction of the handle body 32. More specifically, as shown in FIG. 5 (a), the cam 33 is a surface 32 a of the handle body 32 and the center of the shaft 31 when the handle body 32 is laid down on the rear side of the upper surface of the slider body 1. It protrudes from the front to the bottom. The downward protrusion length of the cam 33 with respect to the one surface 32a is a length sufficient to elastically deform the elastic body 2 when the handle body 32 is inclined rearward as shown in FIG. The pull main body 32 is pushed in by elastic deformation of the elastic body 2 by 33, and is laid down on the rear side.

  As shown in FIG. 2, the elastic body 2 is a leaf spring, is a flat plate having a constant thickness, and has a rectangular shape whose long side is sufficiently longer than the short side. In the example in the figure, the long side is three times longer than the short side. The leaf spring 2 is attached to the slider body 1.

  As shown in FIGS. 1 to 6, the slider body 1 has an upper wing plate 4 and a lower wing plate 5 which are opposed to each other with a space in the vertical direction, and the upper wing plate 4 and the lower wing plate 5 are arranged at the center in the left-right direction at the front part of each other. The upper and lower ends of at least one of the upper wing plate 4 and the lower wing plate 5 (both in the drawing) are moved up or down so as to narrow the vertical distance between the connecting column 6, the upper wing plate 4 and the lower wing plate 5. A pair of projecting flanges 7 and 7 and a pair of handle attachment columns 8 and 8 projecting from the front and rear central portions of the upper surface of the upper blade 4 in a state of being opposed to each other with a space left and right are provided.

The slider body 1 includes an element passage 11 through which a pair of element rows pass at the center in the left-right direction as an internal space, and a pair of tape grooves through which the tape to which the element is attached is passed at both ends in the left-right direction. 12 and 12 are provided.
The element passage 11 penetrates in the front-rear direction, the rear side is a single passage having a wide width, and the front side is two passages bifurcated left and right by the connecting pillar 6. A portion above the element passage 11 corresponds to the upper portion of the slider body 1.
The tape groove 12 penetrates in the front-rear direction, and in the left-right direction, the left and right center side of the slider body 1 communicates with the element passage 11 and the left and right end sides of the slider body 1 are opened to the outside.

The pair of handle attachment columns 8, 8 are opposed to each other with a space left and right, and project upward from the front and rear central portions of the upper surface of the upper blade 4. The pull attachment column 8 includes a front column 81 and a rear column 82 which face each other with a space in the front and rear direction.
Before attaching the handle 3, as shown in FIGS. 2 and 3, a U-shaped shaft insertion groove 83 that opens upward in a side view is formed between the front pillar 81 and the rear pillar 82 so as to penetrate in the left-right direction. The front-rear interval between the upper portions of the front column 81 and the rear column 82 is wider than the diameter of the shaft 31 of the handle 3.
On the other hand, after attaching the pull handle 3, as shown in FIGS. 1, 4, and 5, the upper portions of the front column 81 and the rear column 82 are plastically deformed in a direction approaching each other and are almost in contact with each other. The distance between the upper portions of the shaft 31 becomes narrower than the diameter of the shaft 31, and the shaft 31 is restrained so as not to be detached. Further, after attaching the pull handle 3, the shaft insertion groove 83 becomes an annular shaft hole 84 as viewed from the side. The shaft 31 is rotatably supported in the pair of shaft holes 84 and 84.

  The upper wing plate 4 includes a plate-like upper wing plate main body 41 that covers the upper portion of the element passage 11, a recess 42 that is recessed on the upper surface of the upper wing plate main body 41, and a pair of puller attachment columns 8, 8. A pair of stopper portions 46, 46 projecting from the upper surface of the main body 41 and defining the front side of the swing range of the handle 3 are provided.

  As shown in FIGS. 3 and 6, the recess 42 includes an elastic body recess (spring recess) 43 that houses the elastic body (leaf spring) 2, a shaft recess 44 on which the left and right ends of the shaft 31 are placed, and a rear And a pulling recess 45 for placing the pulling main body 32 in a state of being tilted to the side.

  When viewed in plan, the spring recess 43 has a rectangular shape extending in a straight line from side to side, and its left and right length (horizontal width) is the length that reaches the inside of the pair of shaft holes 84 and 84, and the leaf spring 2 is placed in the inside. It is housed with a gap in the front and rear. Accordingly, the leaf spring 2 also extends to the left and right until it reaches the inside of the pair of shaft holes 84, 84. Further, the front and rear length (vertical width) L2 of the spring recess 43 is slightly longer than the front and rear length (vertical width) L1 of the leaf spring 2, as shown in FIG. 82, the front and rear opposing surfaces of the lower ends of the pair of front pillar 81 and rear pillar 82 are part of the front and rear faces of the spring recess 43 (left and right). End).

  The spring recess 43 includes a flat portion 43a on which the left and right ends of the leaf spring 2 are placed at the left and right ends, and a bending allowance portion that allows the left and right center portions of the leaf spring 2 to bend at the left and right center portions. 43b. The flat portion 43a has an outer end and an inner end in the left-right direction inside the shaft insertion groove 83 (shaft hole 84) (within a range extending in the left-right direction), and both ends in the front-rear direction are the front pillar 81 and the rear pillar 82. Are on the opposing surfaces of the lower end portions of each other. The left and right ends of the bending allowance portion 43b coincide with the inner ends in the left-right direction of the pair of flat portions 43a and 43a. Moreover, the bending | flexion permission part 43b is formed in the cross-sectional circular arc shape which becomes deep gradually from left-right both ends toward the left-right center.

As shown in FIG. 3, the shaft recess 44 is formed on the left and right outer sides of the spring recess 43, and includes a pair of mounting portions 44a and 44a. Further, when viewed in plan, the shaft recess 44 and the spring recess 43 have a rectangular shape extending in a straight line from side to side as a whole, and left and right ends as a whole (the left end of the left mounting portion 44a and the right mounting portion 44a). Is located outside the left and right ends of the pair of handle attachment columns 8 and 8 and inside the left and right ends of the upper blade body 41. Further, the overall lateral width W3 of the shaft concave portion 44 and the spring concave portion 43 is wider than the interval W1 between the pair of pull attachment brackets 8 and 8, and smaller than the lateral width W2 of the upper blade body 41.
As shown in FIG. 6, the upper surface, which is the bottom of the mounting portion 44 a, is set to be higher than the upper surface of the spring recess 43 and higher than the upper surface of the leaf spring 2 placed on the spring recess 43. The upper surface of the mounting portion 44 a is also the lower surface of the pair of shaft holes 84 and 84 and serves as a mounting surface on which the left and right end portions of the shaft 31 are placed. As shown in FIG. 5B, the upper surface of the mounting portion 44a is formed in a cross-sectional arc shape that gradually becomes deeper from the front and rear ends toward the front and rear centers.

  The pulling recess 45 extends in the front-rear direction from one end of the upper surface of the upper blade main body 41 toward the other end side than the pulling attachment column 8. In the figure, it is formed over a range from the front end of the pull handle attachment column 8 and the front end of the upper blade body 41 to the rear end of the upper surface of the upper blade body 41. Further, the pulling recess 45 is formed over the entire length W1 between the pair of pulling attachment columns 8 and 8 in the left-right direction. As shown in FIG. 5, the pulling recess 45 is located below the upper surface of the shaft recess 44 and above the upper surface of the flat portion 43 a in the vertical direction. The pull-in recess 45 is formed in a horizontal plane, and the pull-down main body 32 lying on the rear side is placed on this, and the limit position on the rear side of the swing range of the pull-in hand 3 is determined. On the other hand, it is the stopper portion 46 that defines the front limit range of the swing range of the puller 3.

  As shown in FIGS. 3 and 5, the stopper portion 46 protrudes upward from the front portion of the left and right end portions of the upper surface of the pulling recess 45, and the inner side surface (on the pulling recess 45 side) of the left and right sides of the front pillar 81. Projects laterally from the side. In addition, since the pair of stopper portions 46 and 46 are formed symmetrically, the pair of stopper portions 46 and 46 protrude from the opposing surfaces of the pair of handle attachment columns 8 and 8 toward the left and right central sides. As shown in FIG. 5C, the pair of stopper portions 46, 46 are placed on the left and right side surfaces 32 c, 32 c of the handle body 32 in a state of lying down on the front side, and determine the front limit position of the swing range of the handle 3. . More specifically, the pair of stopper portions 46 and 46 are in point contact with the corner portions 32c1 of the pair of side surfaces 32c and 32c of the handle main body 32.

  As shown in FIG. 3, the slider S of the first embodiment described above has a shaft insertion groove 83 between the pair of front pillars 81 and the rear pillars 82 as shown in FIG. Among them, the narrowest distance is the distance between the lower ends of the pair of front pillar 81 and rear pillar 82, that is, the vertical width L <b> 2 of the shaft recess 44 and the spring recess 43. Further, the front-rear distance above the lower ends of the pair of pull handle attachment columns 8 is equal to or longer than the vertical width L2. Since the diameter of the shaft 31 and the vertical width L1 of the leaf spring 2 are shorter than the longitudinal width L2, the shaft 31 and the leaf spring 2 can be easily passed between the pair of pull attachment columns 8 and 8 from above, and the leaf spring 2 Can be easily placed on the spring recess 43 and the shaft 31 can be easily placed on the shaft recess 44. Then, if the upper part of the front pillar 81 and the rear pillar 82 is crimped and plastically deformed so as to be close to each other, the U-shaped shaft insertion groove 83 becomes an annular shaft hole 84, and the front pillar 81 and the rear pillar 82 Of the shaft 31 holds the left and right ends of the shaft 31 so that they cannot be detached. Further, since the front and rear opposing surfaces of the lower ends of the front column 81 and the rear column 82 form a part of the front and rear surfaces of the spring recess 43, the front column 81 and the rear column are compared with a structure without the spring recess 43. The strength of 82 is weakened, and it becomes easy to plastically deform the upper portions of the front column 81 and the rear column 82 so as to approach each other. In addition, the front and rear facing surfaces of the lower ends of the front column 81 and the rear column 82 are recessed over the entire length of the left and right sides (recessed by the spring recess 43 and the shaft recess 44). The overall height of the side is increased by the amount of the spring recess 43, and the upper portions of the front column 81 and the rear column 82 are easily plastically deformed so as to approach each other.

  The slider S assembled in this way has the following effects. Since the spring recess 43 includes a pair of flat portions 43a, 43a at the left and right ends and a curved portion 43b at the left and right central portions, the left and right ends of the leaf spring 2 are placed on the pair of flat portions 43a, 43a. The leaf spring 2 is stable and difficult to come off. Moreover, since the leaf spring 2 is positioned over the entire length of the width just below the shaft 31, the leaf spring 2 is hardly seen when viewed in plan, and the appearance is good. Further, when the handle 3 is tilted backward, the cam 33 of the handle 3 comes into contact with or approaches the front and rear center portion of the leaf spring 2 from above. Whether it comes into contact or close depends on the dimensional accuracy of the components of the slider S. There are two types of contact. The first contact form is a case where the cam 33 slightly elastically deforms the leaf spring 2 in its thickness direction. The second contact form is a case where the leaf spring is simply in contact without undergoing any elastic deformation in the thickness direction. In the case of the first contact form, the restoring force of the leaf spring 2 pushes the cam 33 and the handle 3 upward, so that a part of the handle main body 32 and the handle recess 45 come into surface contact. In the case of the second contact configuration and the proximity configuration, the restoring force of the leaf spring 2 cannot be obtained, but a part of the flat surface portion 32a of the handle main body 32 and the pedestal portion 45 are in surface contact. In either case of the contact form or the proximity form, the handle 3 can be stably placed in the pull-in recess 45, and the pull 3 can be kept low by the depth of the pull-in recess 45.

  Further, when the slider S is used in a state where the handle 2 is turned slightly upward and tilted backward in order to separate the element rows of the slide fastener, the leaf spring 2 is pushed by the cam 33 as shown in FIG. , Elastically deform. Since the spring recess 43 and the leaf spring 2 are extended to the left and right so as to reach the inside of the pair of shaft holes 84, 84, for example, the spring recess and the plate are larger than the interval W1 between the pair of pull handle attachment columns 8, 8. Compared to a slider in which the lateral width of the spring is shortened, the lateral width of the leaf spring 2 can be increased, and the leaf spring 2 is easily elastically deformed. In addition, since the upper surface, which is the bottom of the shaft recess 44, is set higher than the upper surface of the leaf spring 2 placed on the spring recess 43, there is a vertical space between the leaf spring 2 and the shaft 31. Then, only the cam 33 contacts the leaf spring 2 in the puller 3, and the shaft 31 does not disturb the elastic deformation of the leaf spring 2 when the cam 33 contacts the leaf spring 2. Accordingly, the leaf spring 2 is easily elastically deformed. In addition, since the leaf spring 2 is accommodated in the spring recess 43 with a gap between the front and rear, the leaf spring 2 is easily elastically deformed.

  Further, when the handle 3 is rotated forward, the pair of stopper portions 46 and 46 and the handle main body 32 collide with each other, and the swing of the handle 3 forward is prevented. Further, the upper end portions of the pair of stopper portions 46, 46 and the corner portions 32c1, 32c1 of the left and right side surfaces 32c, 32c of the handle main body 32 are in point contact. Since the scratches caused by the point contact are the left and right side surfaces 32c and 32c of the handle body 32 and the pair of corner portions 32c1 and 32c1, the influence on the appearance of the handle body 32 can be reduced. The stopper portion 46 is supported by the side surface of the pull handle mounting column 8 and is not easily damaged.

  As shown in FIG. 8, the slider body 1 used in the first modification of the slider according to the first embodiment of the present invention has a concave portion 42 composed of only a spring concave portion 43 and a pulling concave portion 45, and a shaft concave portion 44. There is no difference from the slider body 1 used in the first embodiment.

  The inner and outer ends in the left and right direction of the pair of flat portions 43a and 43a in the spring recess 43 are both positioned outside the outer surface of the left and right side surfaces of the pair of pull handle attachment columns 8 and 8. Therefore, the spring recess 43 extends to the left and right outside of the pair of shaft insertion grooves 83 and 83 (shaft holes). In addition, the left and right outer ends of the pair of flat portions 43 a and 43 a are located inside the left and right ends of the upper blade body 41.

  According to the slider body 1, if a leaf spring 2 having a size slightly smaller than the spring recess 43 (extending to the left and right outside of the pair of shaft insertion grooves 83, 83) is used, The length (width) is longer than that of the leaf spring 2 of the first embodiment, and the leaf spring 2 is easily elastically denatured by the length. In this case, the shaft 31 of the handle 3 is placed on and in contact with the leaf spring 2.

  As shown in FIG. 9, the slider body 1 used in the second modification of the slider according to the first embodiment of the present invention is provided with groove portions 41 a before and after the lower end portion of each pulling attachment column 8. This is different from the slider body 1 used in the modification.

  A total of four grooves 41 a are formed on the upper surface of the upper blade body 41. For example, one groove portion 41 a is formed over the entire length of the rear column 82 adjacent to the lower end of the rear surface of the left rear column 82. The other three grooves 41a are also formed in the left and right front pillars 81 and the right rear pillar 82 in the same manner. These groove portions 41a increase the overall height of the front and rear surfaces of the pull handle attachment column 8 as compared with the case where there is no groove portion 41a, and when the shaft 31 is attached, the upper ends of the front column 81 and the rear column 82 are easily plastically deformed.

  The left and right inner ends of the pair of flat portions 43a and 43a in the spring recess 43 are located inside the pair of shaft insertion grooves 83 and 83 (shaft holes). Further, the left and right outer ends of the pair of flat portions 43 a and 43 a are located on the left and right outer sides of the pair of shaft insertion grooves 83 and 83 and on the inner sides of the left and right ends of the upper blade body 41.

  The present invention is not limited to the above-described embodiment and its modifications, and can be changed as appropriate without departing from the spirit of the present invention. For example, the recessed part 42 should just be provided with the recessed part 43 for elastic bodies at least among the recessed part 43 for elastic bodies, the recessed part 44 for an axis | shaft, and the recessed part 45 for a handle.
