Description

  The present invention relates to a fixture for fixing an object.

  When fixing a relatively hard object to an object to be fixed that has screws, nails, etc. (hereinafter referred to as “screws, etc.”) using a fixing auxiliary object such as a nut, the following work is generally performed. Be seen. First, a hole that is larger than the diameter of the insertion portion such as a screw and smaller than the portion of the fixed object to which the screw or the like is connected is made in the object, and the insertion portion such as the screw is passed through the opened hole. Here, the insertion portion refers to a portion such as a screw which is expected to be inserted into an object. Then, in that state, insert a screw or the like into the target object, and screw until the clearance between the target object to which the screw or the like is connected and the target object and the clearance between the target object and the fixing auxiliary object disappear. Insert the insertion part, etc., into the hole of the fixing aid and fit it. For example, when the screw or the like is a screw, the screw thread is screwed into the screw groove formed on the side surface of the hole in the nut which is the fixing aid. As a result, the object is fixed to the screw or the like with a certain strength. Since there is no gap between the object to be fixed in which the insertion part such as a screw is formed and the object, and between the object and the fixing auxiliary object, the object, the fixing auxiliary object and the object to be fixed are mutually It will be fixed.

  However, a structure in which such an object, a fixed object, and a fixing auxiliary are combined is often structurally weak. This is because, as described above, the hole provided in the object is larger than the diameter of the insertion portion such as the screw, so that a gap is generated between the inside of the hole of the object and the insertion portion such as the screw. As described above, the portion of the fixed object to which the screw or the like is connected and the object, and the object and the fixing auxiliary object are only fixed by contact, so if there is the above-mentioned gap, at these contact portions. Skidding occurs. The cause may cause so-called rattling.

  As a method for solving the above problem, Patent Document 1 discloses the following technique. That is, a bent piece that is slightly projected along the inner surface of the mounting hole of the mounted body and is inserted into the mounting hole is disposed on the surface of the mounted body. After that, the mounted body is brought into contact with the conductive mounting body, and the mounted body is tightly screwed into the hole of the conductive mounting body with a conductor screw inserted through the bent piece in the mounting hole, Forcibly bend the bent piece.

  Further, in relation to the present invention, Patent Document 2 discloses a technique for compressing, press-fitting, and fastening while deforming a molding material into an introduction hole in a tapered outer peripheral portion of an automobile subframe / rigid collar. .

JP-A-7-57793 JP, 2011-88552, A

  In the technology disclosed in Patent Document 1, the bending piece is simply formed by bending a plate, and the attached body is forcibly bent by tightly screwing the attached body to form the attached body. Although it could be attached, there was a problem that its attachment accuracy was poor. This is because the bending directions of the parts forming the bent pieces are not constant.

  FIG. 1 is a conceptual diagram showing a fixing device 001a including two side portions. The figure (a) is a top view, the figure (b) is a side view on the assumption that the direction of the arrow 091aa shown in the figure (a) is seen, and the figure (c) is the figure ( It is a side view assuming the case where the direction of arrow 091ab shown in a) is seen.

  The fixture 001a includes a support portion 013a, a side portion 011aa, and a side portion 011ab.

  The side portion 011aa is in contact with the projecting portion 014aa of the support portion 013a and is held by the support portion 013a. The side portion 011ab is in contact with the projecting portion 014ab of the support portion 013a and is held by the support portion 013a.

  Here, the "projected portion" is a portion of the surface of the support portion that is a boundary with the side portion. The projected portion is a surface of a boundary between the assumed supporting portion and a side portion, assuming that the supporting portion near the protruding portion has a shape continuous with the surrounding supporting portions. Here, the shape continuous with the surroundings means that, for example, if the surface of the supporting portion around the projecting portion is a flat surface, the surface of the projecting portion is also a plane connected to the flat surface. is there. As will be described later, the supporting portion and the side portion may be integrally formed, but even in that case, the projecting portion is recognized by the above method. Then, it is considered that the supporting portion and the side portion are in contact with each other by the protruding portion, and the side portion is held by the supporting portion. These are the same below.

  The point 085a is the center of gravity of a figure composed of two centers of gravity of the projected portion 014aa and the projected portion 014ab.

  The angle formed by the straight line connecting the center of gravity of the projected portion 014aa and the point 085a and the straight line connecting the center of gravity of the projected portion 014ab that is the projected portion adjacent to the projected portion 014aa and the point 085a are It is about 180 degrees.

  That is, the projecting portion 014aa and the projecting portion 014ab are at positions having secondary rotational symmetry in the annular support portion 013a having secondary rotational symmetry. Also, the side portion 011aa and the side portion 011ab are located on the same side of the plane including the ring.

  An angle 087ab formed by a line 084ab, which is the center line of the side portion 011ab parallel to the protruding portion 014ab in the side portion 011ab, at a position intersecting the center line of the protruding portion 014ab. Is about 90 degrees. Here, the direction away from the projecting portion 014ab is the direction indicated by the arrow 091ac. Further, the circumferential direction is a direction parallel to the direction of the arrow 091ad at the position where it intersects with the center line of the projecting portion 014ab.

  Similarly, in the circumferential direction of the support part 013a at the position where the center line of the side part 011aa parallel to the direction in which the side part 011aa is in contact with the projected part 014aa intersects the center line of the projected part 014aa. The angle with respect to it is about 90 degrees.

  The side portion 011aa has a bent portion 071aa protruding toward the side portion 011ab due to the bending of the bent portion 071aa.

  The side portion 011ab is bent in the bent portion 012ab so that the bent portion 012ab protrudes toward the side portion 011aa.

  Although various materials such as metal and resin can be used for the supporting portion 013a, it is preferable that the supporting portion 013a is a material having a hardness sufficient to maintain the shape while holding the side portions 011aa and 011ab.

  The material of the side portions 011aa and 011ab is a material that can be deformed to some extent by pressing and is not too soft except at least in the vicinity of the projecting portion and the end opposite to the projecting portion. preferable. The reason will be described later. Further, it is more preferable to use a material that is unlikely to deteriorate such as oxidation. Also, when considering the price, it is preferable to use a material that is not too expensive. Typical examples of such a material include aluminum, copper, lead, zinc, tin, alloys thereof, or hard rubber or resin.

  The material included in the side portions 011aa and 011ab is at least in the vicinity of the projecting portion and in the vicinity of the end portion on the side opposite to the projecting portion, in the vicinity of the projecting portion and in the vicinity of the end portion on the side opposite to the projecting portion. It is preferable that the material is the same as or harder than that.

  The supporting portion 013a and the side portions 011aa and 011ab may be made of the same material or different materials.

  Further, the side part 011aa and the side part 011ab may include different materials.

  The bent portion may be formed anywhere as long as it is at a position other than the end portion of the side portion.

  The configuration shown in FIG. 1 can be manufactured by the steps shown in FIGS. 2 and 3, for example.

  First, prepare a plate of material.

  Then, the material plate is processed into a shape as shown in FIG. The figure (a) is a top view, and the figure (b) is a sectional view assuming the case of cutting along the line 084h shown in the figure (a). Cutting, cutting, die cutting, or the like can be used for the processing when processing the shape shown in FIG.

  Next, in the portions indicated by the lines 084i and 084j shown in the figure, the portion directed from the line 084i to the arrow 098c and the portion directed from the line 084j to the arrow 098d are bent in the direction indicated by the arrow 098e. Bending at that time can be performed by pressing, for example.

  As a result, the structure shown in FIG. 3 is obtained. The figure (a) is a top view, and the figure (b) is a sectional view assuming a case of cutting along the line 084k shown in the figure (a).

  Next, in the portions indicated by the line 084l and the line 084m shown in the figure, the portion in the direction of the arrow 098c from the line 084l and the portion in the direction of the arrow 098d from the line 084m are respectively bent in the direction of the arrow 098f. . Bending at that time can be performed by pressing, for example.

  In this way, 001a shown in FIG. 1 can be created.

  Next, an operation example of fixing an object with a screw member and a nut using the fixture 001a will be described.

  FIG. 4 is a conceptual diagram showing a screw member 041, a nut 031 and an object 051 to be fixed, which is used in the description of the operation example below. 11A and 11B show a screw member 041, FIGS. 11C and 11D show a nut 031, and FIGS. 11E and 11F show an object 051. Further, (a), (c), and (e) of the same drawing are top views, and (b), (d), and (f) of the same drawing are cross-sectional views assuming the case of cutting along lines 084n, 084o, and 084p. It is a figure.

  The screw member 041 includes a member 048 and a shaft 042.

  The shape of the member 048 is a rectangular parallelepiped.

  The axis 042 has a cylindrical shape with a diameter of 047, and a line 084a representing the central axis of the cylindrical shape is perpendicular to the upper surface 062a. A portion of the shaft 042 above the shaft 042 in the figure is a thread portion 044 having a thread on its side surface.

  The nut 031 includes a rectangular parallelepiped member 038. The member 038 has a hole 036 formed by hollowing out a cylindrical shape having a diameter 037. A line 084b representing the central axis of the cylindrical shape is perpendicular to the upper surface 062b. The side surface of the hole 036 is a thread groove portion 034 in which a thread groove that is screwed into contact with the thread of the thread portion 044 is formed.

  The object 051 includes a rectangular parallelepiped member 058.

  In the member 058, a hole 056 having a shape of a cylinder having a diameter 057 larger than the diameter 047 shown in FIG. 14A is formed, and a line 084c representing the central axis of the cylinder is perpendicular to the upper surface 062c. .

  FIG. 5 is a conceptual sectional view showing a fixed state when the screw member 041, the nut 031 and the object 051 shown in FIG. 4 are fixed without using the fixing device of the present embodiment. .

  By tightening the nut 031 on the shaft 042 of the screw member 041, the surfaces 061a and 061c that are the lower surface of the nut 031 come into contact with the surfaces 061b and 061d that are the upper surface of the object 051, respectively. Further, the surfaces 061f and 061h which are the upper surfaces of the member 048 of the screw member 041 are in contact with the surfaces 061e and 061g which are the lower surfaces of the member of the object 051.

  Since the surface of each surface is not a flat surface but has some unevenness, contact between them causes the unevenness to mesh with each other. Therefore, even if a force is applied to the object in the direction of arrow 094, if the force is sufficiently small, the relative position of the object 051 with respect to the screw member 041 and the nut 031 is caused by the engagement of the unevenness. Does not fluctuate. That is, the object 051 is temporarily fixed to the screw member 041 and the nut 031.

  However, the screw thread of the screw member 041 and the screw groove of the nut 031 are not completely in contact with each other, there is a gap, and further, the screw groove and the screw thread can be deformed when a strong force is applied. . Therefore, the relative positions of the nut 031 and the screw member 041 in the direction parallel to the direction of the arrow 094 may change. Therefore, when the unevenness is small, if the relative force applied to the object 051 in the direction of the arrow 094 with respect to the shaft 042 is large, the unevenness rides up and the direction of the arrow 094 with respect to the screw member 041 is increased. There is a variation in position relative to. Alternatively, when the force applied to the object 051 in the direction of the arrow 094 is large, the meshed unevenness may be crushed and the above fluctuation may occur. That is, the object 051 can move in the direction of arrow 094.

  FIG. 6 is a conceptual cross-sectional view showing a state where the object 051 moves in the direction of arrow 094 as a result of the force being applied to the object 051 in the direction of arrow 094 in FIG.

  The relative movement of the object 051 with respect to the screw member 041 and the nut 031 as described above is at least part of a so-called rattling generation mechanism.

  7 to 11 are image diagrams of a cross section showing an example of a fixed state of the object 051 with the screw member 041 and the nut 031 when the fixing device 011a of the present embodiment is used.

  FIG. 7 is a diagram showing a state in which the shaft 042 of the screw member 041 is inserted into the hole 056 of the object 051 and further the fixing device 001a is inserted into the hole 056. The insertion is performed so that the projecting portion 014aa and the projecting portion 014ab face upward in FIG. The nut 031 has not yet been inserted into the shaft 042.

  In this state, the nut 031 is inserted into the shaft 042 in the direction of arrow 095 while screwing the thread groove of the nut 031 and the thread of the shaft 042 into contact with each other.

  FIG. 8 shows a state in which, as a result of inserting the nut 031 into the shaft 042, the surfaces 061a and 061c that are the lower surfaces of the nut 031 are in contact with the upper surfaces of the support portions 013a above the projecting portions 014aa and 014ab, respectively.

  In the state shown in the figure, the surfaces 061a and 061c that are the lower surface of the nut 031 are in contact with the projecting portions 014aa and 014ab, respectively, but the side portions 011aa and 011ab have not been deformed yet.

  FIG. 9 shows a state in which the nut 031 is tightened so that the nut 031 is inserted deeper into the shaft 042. In this state, the side portions 011aa and 011ab are deformed by the projecting portions 014aa and 014b being pushed in the direction of the arrow 095, and become side portions 011aax and 011abx. As a result of the deformation, the bent portion 071aa of the side portion 011aa and the bent portion 071ab of the side portion 011ab shown in FIG. 8 move in the directions having the components of the directions of the arrows 098a and 098b, respectively, and the deformed bend shown in FIG. Parts 071aax and 071abx. The bent portion 071aax and the bent portion 071abx are in contact with the side surface of the shaft 042, respectively.

  When the nut 031 is further tightened, the side portions 011aax and 011abx are pushed in the direction of arrow 095. Thereby, the bent portion 071aax pushes the side surface of the shaft 042 in the direction parallel to the direction of the arrow 098a, and the bent portion 071abx pushes the side surface of the shaft 042 in the direction including the component of the direction of the arrow 098b. The axis 042 is hardly deformed in the direction including the components in either direction of the arrows 098a and 098b.

  Therefore, as shown in FIG. 10, the both side portions are deformed into the side portions 011aay and 011aby. The contact area between the side portion 011aay and the side surface of the shaft 042 and between the side portion 011aby and the side surface of the shaft 042 is larger than the contact area shown in FIG. 9. Here, the contact area shown in FIG. 9 is the contact area between the side portion 011aax and the side surface of the shaft 042 and the side portion 011abx and the side surface of the shaft 042 in FIG. 9.

  When the nut 031 is further tightened, the side portion is further deformed, as shown in FIG. 11. In the state shown in the figure, both side portions are further deformed into side portions 011aaz and 011abz. The side portion 011aaz and the side surface of the shaft 042 are in contact with each other at a portion surrounded by a line 081a, and the side portion 011abz and a side surface of the shaft 042 are in contact with each other at a portion surrounded by a line 081b.

  In the state shown in the figure, the shapes of the side portion 011aaz and the side portion 011abz are substantially the same, and therefore, the central axis 084c of the hole 056 and the central axis 084a of the shaft 042 are substantially the same.

  Furthermore, the end portion 074a of the side portion 011aaz is in the direction of the arrow 094b with respect to the corner portion 088b of the object 051, and it is difficult to move further in the direction of the arrow 094b. Further, the end portion 074b of the side portion 011abz faces the corner portion 088d of the object 051 in the direction of the arrow 094a, and it is difficult to move further in the direction of the arrow 094a.

  Further, the side portion of the side portion 011aaz in the vicinity of the contact portion 014aa is in the direction of arrow 094b with respect to the corner portion 088a of the object 051, and it is difficult to move further in the direction of arrow 094b. The side portion near the contact portion 014ab of the side portion 011abz faces the corner portion 088c of the object 051 in the direction of the arrow 094a, and it is difficult to move further in the direction of the arrow 094a.

  As described above, it is difficult for the object 051 to move relative to the axis 042 in either direction of the arrows 094a and 094b. That is, the screw member 041, the nut 031 and the object 051 are fixed with a certain strength.

  In the fixing device 001a shown in FIG. 1, the side portions 011aa and 011ab project in a direction in which it is assumed that the shaft 042 of the screw member 041 is present during use (see FIGS. 7 and 8). In addition, a plurality of side portions 011aa and 011ab are present on the side portion. Then, the side portion 011aa and the side portion 011ab are held in contact with the projecting portions 014aa and 014ab of the support portion 013, which are equidistant in the circumferential direction. Further, the center line of the side portion parallel to the direction in which the respective side portions are in contact with the projecting portion in contact with each other and the circumferential direction of the support portion 013 at the position intersecting the center line of the projecting portion are substantially the same. Vertical.

  Therefore, when the nut 031 is screwed onto the shaft 042 of the screw member 041 and tightened, the probability that the protrusions on the respective side parts come into contact with the shaft parts at equal intervals in the circumferential direction is improved. Then, after that, the side portion is deformed so as to increase the contact portion with the shaft 042, and the shaft 042 is tightened. At this time, as described above, the probability that the protrusions on the respective side portions come into contact with the portions of the shaft 042 at equal intervals in the circumferential direction is improved. In that case, the forces applied to the respective side portions during the subsequent deformation of the side portions are evenly applied. Therefore, the probability that the side portions 011aa and 011ab are uniformly deformed is improved. Therefore, the probability that the shapes of the side portions 011aaz and 011abz after deformation in the fixed state become uniform is improved. The positional relationship between the hole 056 formed in the object 051 and the shaft 042 of the screw member 041 depends on the shape of the deformed side portions 011aaz and 011abz in the fixed state. Is constant. Therefore, the fixture 001a shown in FIG. 1 can improve the positional accuracy of the object 051 in the fixed state with respect to the screw member that is the object to be fixed. Further, since the shaft 042 is tightened on both sides of the shaft 042 at equal intervals, rattling between the attached object and the shaft can be suppressed.

  7 to 11 show a case where the fixing device is inserted into the hole 056 so that the supporting portion 013a shown in FIG. However, there is a case where the fixing device is inserted into the hole so that the supporting portion 013a is located below.

  FIG. 12 is an image diagram of a cross section on the assumption that the configuration shown in FIG. 11 is cut along the line 082 shown in FIG. FIG. 12 shows only the shaft 042 and two side portions of the screw member 041 shown in FIG. 11. The figure (a) is a figure supposing the case where the material with which a side part is equipped is hard, and the figure (b) is the figure supposing that the material with which a side part is equipped is soft.

  When the material provided in the side portion is hard, in the state shown in FIG. 11, the deformation of the cross-sectional shape of the side portion from the case shown in FIGS. 7 and 8 is small from the case shown in FIGS. 7 and 8, It becomes a shape like the side part 011aaa and the side part 011aba.

  On the other hand, when the material provided in the side portion is soft, the cross-sectional shape of the side portion is largely deformed in the state shown in FIG. 11, and the side portions 011aab and 011abb are formed.

  In the case of the shape shown in FIG. 7A, the contact area between the side portion 011aaa and the side surface of the shaft 042 and the side portion 011aba and the side surface of the shaft 042 are small. Therefore, when a relative force with respect to the shaft 042 is applied to the side part 011aaa or the side part 011aba in the direction of the arrow 096, the side part 011aaa and the side surface of the shaft 042, and the side part 011aba and the shaft 042. There may be a gap between the side and the side. Therefore, an excessively hard material may not be suitable as a material provided on the side portion from the above viewpoint.

  On the other hand, in the case of the shape shown in the same figure (b), the contact area between the side part 011aab and the side surface of the shaft 042, and the contact area of the side part 011abb and the side surface of the shaft 042 are as shown in the same figure (a). Greater than Further, the surface of the side portion 011aab in contact with the side surface of the shaft 042 is curved along the shape of the side surface of the shaft 042, and the surface of the side portion 011abb in contact with the side surface of the shaft 042 is It is curved along the shape of the side surface of the shaft 042. Therefore, even if a relative force with respect to the shaft 042 is applied to the side portion 011aab or the side portion 011abb in the direction of the arrow 096, the side portion 011aab and the side surface of the shaft 042, and the side portion 011abb and the shaft 042 can be formed. The gap between the side surface and the side surface is unlikely to occur. However, if the material included in the side portions 011aab and 011abb is too soft, the same material is deformed, so that the positional relationship between the side portion 011aab and the side surface of the shaft 042 and the side portion 011abb and the side surface of the shaft 042 vary. There is a case.

  For the above reason, as described in the description of the side portions 011aa and 011ab shown in FIG. 1, it is preferable that the material of the side portions has an appropriate hardness.

  Various variations can be envisioned for the shape of the side portions.

  FIG. 13 is a conceptual diagram showing the bent side portion 011aa shown in FIG. 1A is a side view on the assumption that the direction corresponding to the direction shown in FIG. 1B is viewed, and FIG. 1B shows the direction of the arrow 091c shown in FIG. It is a side view assuming the case of seeing. The shape shown in FIG. 9A is also a cross-sectional shape that is assumed to be cut along the line 084d shown in FIG.

  The side portion 011aa is bent at the bent portion 071aa. When the side part 011aa is used (when it corresponds to the insertion shown in FIG. 7), the shaft direction of the screw member is opposite to the arrow 091c which is the protruding direction in the cross-sectional shape of the side part 011aa. Is assumed.

  FIG. 14 is a conceptual diagram showing a bent side part 011aac including two bent parts. 1A is a side view on the assumption that the direction corresponding to the direction shown in FIG. 1B is viewed, and FIG. 1B shows the direction of the arrow 091c shown in FIG. It is a side view assuming the case of seeing. The shape shown in FIG. 9A is also a cross-sectional shape that is assumed to be cut along the line 084e shown in FIG.

  The side portion 011aac is bent at the bent portion 071ab and the bent portion 071ac. When the side portion 011aac is used (corresponding to the insertion time shown in FIG. 7), the shaft direction of the screw member is opposite to the arrow 091c which is the protruding direction in the cross-sectional shape of the side portion 011aac. Is assumed.

  FIG. 15 is a conceptual diagram showing the curved side part 011aad. 1A is a side view on the assumption that the direction corresponding to the direction shown in FIG. 1B is viewed, and FIG. 1B shows the direction of the arrow 091c shown in FIG. It is a side view assuming the case of seeing. The shape shown in FIG. 11A is a cross-sectional shape that is assumed to be taken along the line 084f shown in FIG.

  The side portion 011aad is curved as shown in FIG. When the side portion 011aad is used (corresponding to the insertion time shown in FIG. 7), the axis direction of the screw member is opposite to the arrow 091c which is the protruding direction in the cross-sectional shape of the side portion 011aad. Is assumed.

  FIG. 16: is a conceptual diagram showing the side part 011aae provided with an output part. 1A is a side view of a direction corresponding to the direction shown in FIG. 1B, and FIG. 1B is assumed to be the direction of arrow 091c shown in FIG. 1A. It is a side view.

  The side portion 011aae is curved as shown in FIG. When the side portion 011aae is used (corresponding to the insertion time shown in FIG. 7), the shaft direction of the screw member is opposite to the arrow 091c which is the protruding direction in the cross-sectional shape of the side portion 011aae. Is assumed. Then, the side portion 011aae is provided with projecting portions 073a and 073b at the projecting portion in the cross-sectional shape.

  As the material of the protrusions 073a and 073b, for example, resin or metal can be used. The projecting parts 073a and 073b can be created by, for example, joining a projecting part created in advance to a side part before forming the projecting part. Alternatively, when the material is a resin, a resin dissolved in a solvent may be adhered to the side portion before forming the projecting portion, and then the solvent may be evaporated to form the resin.

  In the figure, the projecting portions 073a and 073b having a cylindrical shape are shown, but the projecting portions may have any shape.

  The protrusions 073a and 073b are shown in FIG. 16 (b), which is the central portion of the side portion 011aae with respect to the axis of the screw member, when in use (corresponding to the state shown in FIGS. 9 to 11). It acts as a guide so that the portion of the wire 084g properly contacts. The operation of this guide will be described below.

  17 to 19 are top views showing an operation example of the side portion 011aad having no projecting portion (a view corresponding to the direction of FIG. 1A). In the figure, only the side part 011aad and a part of the shaft 042 are shown.

  FIG. 17 shows a state before the side portion 011aad contacts the shaft 042. From this state, by tightening a nut (not shown), when a force is applied to the projecting portion 014i in the inward direction toward the figure, a projecting portion 089 that is a portion that projects toward the axis of the side portion 011aad. Moves in the direction of arrow 098g with axis 042.

  Then, after coming into contact with the position 077, for example, the side portion 011aav shown in FIG. 18 is deformed (see FIG. 12B) and comes into contact with the shaft 042. Here, the position 077 is the position of the shaft 042 on the assumption that the projection 089 comes into contact with the shaft 042 and is further deformed when the projection 089 moves in the direction of the arrow 098g. In this case, even if a relative force with respect to the shaft 042 is applied to the side portion 011aav in the direction of arrow 097 to some extent, the side portion 011aav does not move relative to the shaft 042 in the direction of arrow 097.

  However, the projecting portion 089 of the side portion 011aad shown in FIG. 17 may move in the direction of the arrow 098g and may be displaced after hitting the shaft 042. This may occur, for example, when the accuracy of attachment of the side portion 011aad to the not-shown support portion (see 013a in FIG. 1) is poor, or when the material of the side portion 011aad is hard. In that case, by further applying a force in the direction of the arrow 098g shown in FIG. 17, the side portion 011aad shown in the same figure is deformed at a position displaced after hitting the shaft 042, and for example, shown in FIG. It becomes like the side part 011aaw. In this case, when a relative force with respect to the shaft 042 is applied to the side portion 011aaw in the direction of arrow 097, the side portion 011aaw is likely to move relative to the shaft 042 in the direction of arrow 097. That is, so-called rattling is likely to occur.

  The output parts 073a and 073b shown in FIG. 16 reduce the probability of becoming like the side part 011aaw shown in FIG. The operation will be described below.

  FIG. 20 shows a state where the protrusions 073a and 073b shown in FIG. 16 are in contact with the shaft 042. In this state, the side portion 011aae is in contact with the shaft 042 at both the protruding portion 073a and the protruding portion 073b, so that the side portion 011aae is in a stable contact state in the direction parallel to the direction of the arrow 097. Therefore, the side portion 011aae is unlikely to shift in the direction parallel to the direction of the arrow 097.

  Accordingly, the side portion 011aae is deformed while being properly abutted on the position 077 which is the position of the shaft 042 which is supposed to come into contact, and becomes, for example, the side portion 011aaex shown in FIG. At this time, the protrusions 073a and 073b shown in FIG. 20 are deformed as the side portions 011aaex are deformed like the protrusions 073ax and 073bx shown in FIG. 21, and are moved to the side of the side portions 011aaex.

  In this way, the protrusions 073a and 073b reduce the probability of becoming the side portions 011aaw shown in FIG.

  As guides that allow the side portions to be deformed without being displaced from the axis, instead of the projecting portions 073a and 073b shown in FIG. 16, depressions provided on the side portions can be used as described below.

  FIG. 22 is a conceptual diagram showing the side portion 011aaf provided with the depression. 1A is a side view of a direction corresponding to the direction shown in FIG. 1B, and FIG. 1B is assumed to be the direction of arrow 091c shown in FIG. 1A. It is a side view.

  The side portion 011aaf is curved as shown in FIG.

  Then, when the side portion 011aaf is used (when inserted in the hole 056 in the same figure as 011aa in FIG. 7), it is assumed that the protruding portion 089f faces the axis (see the axis 042 in FIG. 7). Has been done.

  Further, a recess 075 is formed in the vicinity of the projecting portion 089f of the side portion 011aaf.

  In the same figure, there is shown a case where the vicinity of the recess 075 on the surface opposite to the surface on which the recess 075 is provided on the side portion 011aaf does not project. However, the shape in the vicinity of the recess 075 on the surface opposite to the surface on which the recess 075 is provided is arbitrary. For example, the vicinity of the recess 075 on the surface opposite to the surface on which the recess 075 is provided may project due to the effect of providing the recess 075.

  Next, the effect of the depression 075 will be described.

  FIG. 23 is an image diagram showing a state where the side portion 011aaf shown in FIG. 22 is in contact with the shaft. The side portion 011aaf is in contact with the vicinity of the position 077 of the shaft 042 at the end portion 074c and the end portion 074d of the recess 075. The position 077 is a position where the center of the side part 011aaf contacts the shaft 042 and is deformed in the contact state.

  In this state, the side portion 011aaf is in contact with the shaft 042 at both the end portion 074c and the end portion 074d of the recess 075, and thus is in a stable contact state in the direction parallel to the direction of the arrow 097. Therefore, the side portion 011aaf is unlikely to shift in the direction parallel to the direction of the arrow 097.

  Accordingly, the side portion 011aaaf is deformed without being displaced while hitting the position 077 which is the position of the shaft 042 which is supposed to come into contact, and often becomes, for example, the side portion 011aafx shown in FIG. 24. . The dent 075 has a deformed side portion like the side portion 011aaw shown in FIG. 19, for example, and reduces the probability of rattling.

  The number of the side portions included in the fixing device of the present embodiment is arbitrary as long as it is plural.

  FIG. 25 is a conceptual diagram showing a fixing device 001b having four side portions. The figure (a) is a top view, and the figure (b) is a sectional view assuming the case of cutting along the line 083ba shown in the figure (a). Further, FIG. 11C is a cross-sectional view assuming a case of cutting along line 083bc shown in FIG.

  The fixture 001b includes a support portion 013b and four side portions 011ba, 011bb, 011bc and 011bd.

  The side portions 011ba, 011bb, 011bc, and 011bd are in contact with and held by the projecting portions 014ba, 014bb, 014bc, and 014bd of the support portion 013b having a ring-like shape when viewed from above.

  The point 085c is the center of gravity of the figure composed of the respective centers of gravity of the projecting portions 014ba, 014bb, 014bc, and 014bd.

  The angle formed by the straight line connecting the center of gravity of the projected portion 014ba and the point 085c and the straight line connecting the center of gravity of the projected portion 014bb that is the projected portion adjacent to the projected portion 014ba and the point 085c are It is about 90 degrees.

  The angle formed by the straight line connecting the center of gravity of the projected portion 014bb and the point 085c and the straight line connecting the center of gravity of the projected portion 014bc that is the projected portion adjacent to the projected portion 014bb and the point 085c are It is about 90 degrees.

  The angle formed by the straight line connecting the center of gravity of the projected portion 014cb and the point 085c and the straight line connecting the center of gravity of the projected portion 014bd that is the projected portion adjacent to the projected portion 014bc and the point 085c are It is about 90 degrees.

  The angle formed by the straight line connecting the center of gravity of the projected portion 014bd and the point 085c and the straight line connecting the center of gravity of the projected portion 014ba which is the projected portion adjacent to the projected portion 014bd and the point 085c are It is about 90 degrees.

  That is, the projecting portions 014ba, 014bb, 014bc, and 014bd are at positions having quartic rotational symmetry in the annular support portion 013b having quartic rotational symmetry. Also, the side portions 011ba, 011bb, 011bc and the side portion 011bd are located on the same side of the plane including the ring.

  Position of each of the side portions 011ba, 011bb, 011bc, and 011bd, which is parallel to the direction in which the side portion is in contact with the projecting portion that is in contact with the side portion, intersects with the center line of the projecting portion. The angle formed by the support portion 013b with respect to the circumferential direction is about 90 degrees. These angles correspond to the angles formed by the arrows 091ad and 091ac in FIG. 1 (c).

  The side portions 011ba, 011bb, 011bc and 011bd are bent as shown in the figure at the bent portions 071ba, 071bb, 071bc and 071bd.

  As the side part, various parts including those shown in FIGS. 13, 14, 15, 16 and 22 can be used.

  26 is a sectional view showing a state (a state corresponding to the state shown in FIG. 11) in which the object 051 is fixed by the screw member 041 and the nut 031 shown in FIG. 4 using the fixing device 001b shown in FIG. It is a figure. FIG. 26A is a cross-sectional view assuming a case where the side portions 011ba and 011bc shown in FIG. 25 are cut along a plane including both longitudinal centerlines of the deformed side portions 011baz and 011bcx. Further, FIG. 26B is a cross-sectional view assuming a case where the side portions 011bb and 011bd shown in FIG. 25 are cut along a plane including both longitudinal centerlines of the deformed side portions 011bbz and 011bdx. is there. That is, it is assumed that the figure (b) is a cross section in a direction substantially perpendicular to the figure (a) when viewed from above.

  As shown in FIG. 11A, the object 051 is fixed to the shaft 042 and the nut 031 by the side portions 011baz and 011bcz. Further, as shown in FIG. 11B, the object 051 is fixed to the shaft 042 and the nut 031 by the side portions 011bbz and 011bdz.

  In the fixing device 001b shown in FIG. 25, the side portions 011ba, 011bb, 011bc and 011bd are projected in a direction in which the shaft 042 of the screw member 041 is assumed when the device is used (see FIGS. 7 and 8). There is. Then, the side portions 011ba, 011bb, 011bc and 011bd are held in contact with the projecting portions 014ba, 014bb, 014bc and 014bd of the support portion 013 which are equally spaced in the circumferential direction. Then, the center line of the side portion parallel to the direction in which the respective side portions are in contact with the projected portion that is in contact with each other, and the circumferential direction of the support portion 013b at the position intersecting the center line of the projected portion are substantially Vertical.

  For this reason, when the nut 031 is screwed onto the shaft 042 of the screw member 041 and tightened, the probability that the protrusions on the respective side parts contact the portions of the shaft 042 at equal intervals in the circumferential direction is improved. Then, after that, the side portion is deformed so as to increase the contact portion with the shaft 042, and the shaft 042 is tightened. As described above, since the probability that the protrusions on the respective side portions come into contact with the portions of the shaft 042 at equal intervals in the circumferential direction is improved, how to apply a force to each side portion when the side portions are subsequently deformed. Will be even. Therefore, the probability that the side portions 011ba, 011bb, 011bc, and 011bd are uniformly deformed is improved. Therefore, the probability that the shapes of the side portions 011baz, 011bbz, 011bcz, and 011bdz after deformation in the fixed state become uniform is improved. The positional relationship between the hole 056 formed in the object 051 and the shaft 042 of the screw member 041 depends on the shape of the deformed side portions 011baz, 011bbz, 011bcz, and 011bdz, and this shape is uniform. If so, the positional relationship becomes constant. Therefore, the fixture 001b shown in FIG. 1 can improve the positional accuracy of the object 051 in the fixed state with respect to the screw member that is the object to be fixed. Further, since the shaft 042 is fastened to the equally spaced portions of the shaft 042, rattling between the attached object and the shaft can be suppressed.

  Further, when the fixing device 001b is used, since the shaft is tightened by the four side parts arranged at equal intervals, the shaft 042 is fixed to the shaft 042 as compared with the case where the shaft is fixed by only two facing side parts. The relative position of the object is less likely to change. Here, the case where only the two side portions are fixed is a case where, for example, in FIG. 26, the side portions 011bbz and 011bdz are absent. The difficulty of the relative position variation of the object is determined when a relative force is applied to the axis 042 with respect to the axis having any of the components of the directions 094a, 094b, 094c, and 094d. But it happens. That is, the fixing device 001b has an effect of making rattling less likely to occur as compared with the case where the fixing device 001b is fixed by only two side portions.

  The number of sides may be odd.

  FIG. 27 is a conceptual diagram showing a fixing device 001c having three side portions. The figure (a) is a top view, and the figures (b), (c) and (d) are cross-sectional views assuming the case of cutting along lines 083ca, 083cb, 083cc, respectively.

  The fixture 001c includes a support portion 013c and three side portions 011ca, 011cb and 011cc.

  The side portions 011ca, 011cb and 011cc are held in contact with the projecting portions 014ca, 014cb and 014cc of the ring-shaped support portion 013c, respectively.

  The point 085c is the center of gravity of the figure composed of the respective centers of gravity of the projecting portions 014ca, 014cb, and 014cc.

  The angle formed by the straight line connecting the center of gravity of the projected portion 014ca and the point 085c and the straight line connecting the center of gravity of the projected portion 014cb that is the projected portion adjacent to the projected portion 014ca and the point 085c are It is about 120 degrees.

  The angle formed by the straight line connecting the center of gravity of the projected portion 014cb and the point 085c and the straight line connecting the center of gravity of the projected portion 014cc that is the projected portion adjacent to the projected portion 014cb and the point 085c are It is about 120 degrees.

  The angle formed by the straight line connecting the center of gravity of the projected portion 014cc and the point 085c and the straight line connecting the center of gravity of the projected portion 014ca that is the projected portion adjacent to the projected portion 014cc and the point 085c are It is about 120 degrees.

  That is, the projecting portions 014ca, 014cb, and 014cc are located at positions having third-order rotational symmetry in the annular support portion 013c having third-order rotational symmetry. The side portions 011ca, 011cb and the side portion 011cc are located on the same side of the plane including the ring.

  Circumferential direction of the support portion 013c at a position of the center line of the side portion 011ca, 011cb, and 011cc that is parallel to the direction in which the side portions 011ca, 011cb, and 011cc contact each other, and that intersects with the center line of the protruding portion. The angle formed with respect to is about 90 degrees. The angle corresponds to the angle formed by the arrows 091ad and 091ac in FIG. 1 (c).

  The side portions 011ca, 011cb and 011cc are bent at the bent portions 071ca, 071cb and 071cc as shown in the figure.

  As the side part, various parts including those shown in FIGS. 13, 14, 15, 16 and 22 can be used.

  28 is a conceptual cross-sectional view showing a state (a state corresponding to the state shown in FIG. 11) in which the object 051 is fixed by the screw member and the nut 031 shown in FIG. 4 using the fixing device 001c shown in FIG. Is. FIG. 28A is a cross-sectional view assuming a case where the side portion 011ca shown in FIG. 27 is cut along a plane including both the center line in the longitudinal direction of the deformed side portion 011caz and the center line of the shaft 042. Further, FIG. 28B is a cross-sectional view assuming a case where the side part 011cb shown in FIG. 27 is cut along a plane including both the center line in the longitudinal direction of the deformed side part 011cbz and the center line of the shaft 042. is there. Further, FIG. 28C is a cross-sectional view assuming a case where the side part 011cc shown in FIG. 27 is cut along a plane including both the longitudinal centerline of the deformed side part 011ccz and the centerline of the shaft 042. is there. That is, it is assumed that the figure (b) is a cross section in the direction rotated by 120 degrees when viewed from above with respect to the figure (a), and the figure (c) is seen from above. In this case, it is assumed that the cross section is rotated by 120 degrees.

  As shown in (a), (b) and (c) of the same figure, the object 051 has the axis 042 and the axis 042 from the three directions of 120 degrees when viewed from above by the side portions 011caz, 011cbz and 011ccz. It is fixed to the nut 031.

  In the fixing device 001c shown in FIG. 27, the side portions 011ca, 011cb and 011cc project in a direction in which it is assumed that the shaft 042 of the screw member 041 is in use (see FIGS. 7 and 8). Then, the side portions 011ca, 011cb, and 011cc are held in contact with the projecting portions 014ca, 014cb, and 014cc of the support portion 013, which are equally spaced in the circumferential direction. Further, the center line of the side portion parallel to the direction in which the respective side portions are in contact with the projecting portion in contact with each other and the circumferential direction of the supporting portion 013c at the position intersecting with the center line of the projecting portion are substantially the same. Vertical.

  Therefore, when the nut 031 is screwed onto the shaft 042 of the screw member and tightened, the probability that the protrusions of the respective side parts come into contact with the shaft parts at equal intervals in the circumferential direction is improved. Then, after that, the side portion is deformed so as to increase the contact portion with the shaft 042, and the shaft 042 is tightened. In order to improve the probability that the protrusions of the respective side portions come into contact with the portions of the shaft 042 at equal intervals in the circumferential direction, the force applied to each side portion during the subsequent deformation of the side portions is equal. become. Therefore, the probability that the side portions 011ca, 011cb, and 011cc are uniformly deformed is improved. Therefore, the probability that the shapes of the side portions 011caz, 011cbz, and 011ccz after deformation in the fixed state become uniform is improved. The positional relationship between the hole 056 formed in the object 051 and the shaft 042 of the screw member 041 depends on the shape of the deformed side portion in the fixed state. If this shape is uniform, the positional relationship will be constant. Therefore, the fixture 001c shown in FIG. 27 can improve the positional accuracy of the object 051 in the fixed state with respect to the screw member that is the object to be fixed. Further, since the shaft 042 is fastened to the equally spaced portions of the shaft 042, rattling between the attached object and the shaft can be suppressed.

  Further, when the fixing device 001c is used, the shaft 042 of the screw member 041 is restrained from the three directions by the side portions, and therefore relative to the shaft 042 as compared with the case where it is restrained only by the two opposite side portions. Position is less likely to change. Here, the case of being fixed only at the two opposite side portions is the case shown in FIG. 11, for example. This difficulty of variation occurs even when a relative force is applied to the shaft 042 having a component having any of the directions of arrows 094e, 094f, and 094g shown in FIG. 28. That is, the fixing device 001b has an effect of making rattling less likely to occur as compared with the case where the fixing device 001b is fixed by only two side portions.

  The support portion may have any shape instead of the circular shape.

  FIG. 29 is a conceptual diagram showing a fixing device 001f including a square support portion. The figure (a) is a top view, the figure (b) is a side view on the assumption that the direction of the arrow 091fa shown in the figure (a) is viewed, and the figure (c) is the same ( It is a side view assuming the case where the direction of the arrow 091fb shown in a) is seen.

  The fixture 001f includes a support portion 013f and side portions 011fa and 011fb.

  The side portion 011fa and the support portion 013f are in contact with and held by the projected portion 014fa, and the side portion 011fb and the support portion 013f are in contact with and held by the projected portion 014fb, respectively.

  The point 085f is the center of gravity of a figure composed of the center of gravity of the projecting portion 014fa and the center of gravity of the projecting portion 014fb.

  The angle between the straight line connecting the center of gravity of the projected portion 014fa and the point 085f and the straight line connecting the center of gravity of the projected portion 014fb, which is the projected portion adjacent to the projected portion 014fab, and the point 085f are It is about 180 degrees.

  That is, the projecting portions 014fa and 014fb are at positions having secondary rotational symmetry in the annular support portion 013f having secondary rotational symmetry. The side part 011fa and the side part 011fb are located on the same side of the plane including the ring.

  The angle formed by the center line of the side portion 011fb parallel to the direction in which the side portion 011fb is in contact with the projecting portion 014fb with respect to the circumferential direction of the support portion 013f at the position intersecting the center line of the projecting portion 014fb. 087fb is about 90 degrees. Here, the circumferential direction is a direction parallel to the direction of the arrow 091fd at the position intersecting the center line of the projecting portion 014fb.

  Similarly, with respect to the circumferential direction of the support portion 013f at the position where the center line of the side portion 011fa parallel to the protruding portion 014fa in contact with the side portion 011fa intersects with the center line of the protruding portion 014fa. The angle formed is about 90 degrees.

  The side portion 011fa is bent in the bent portion 071fa such that the bent portion 071fa projects toward the side portion 011fb.

  The side portion 011fb is bent in the bent portion 071fb so that the bent portion 071fb projects toward the side portion 011fa.

As the side part, various parts including those shown in FIGS. 13, 14, 15, 16 and 22 can be used. Also, four side portions may be provided.
Next, a usage example of the fixing device 001f shown in FIG. 29 will be described.

  FIG. 30 is a conceptual diagram showing members other than the fixing device 001f used in the following description of the usage example. (A), (c), (e) and (g) are top views, and (b), (d), (f) and (h) are (a) and (c). ), (E), and (g) are cross-sectional views assuming respective cases of cutting along the lines 084q, 084r, 084s, and 084t. (A) and (b) of the same figure show a screw member 041f, (c) and (d) of the figure show a nut 031f, (e) and (d) of the figure show an object 051f, and (g) of the same figure. (F) represents the spacer 065f, respectively.

  FIG. 31 is a cross-sectional view showing a state in which these members and the fixture 001f shown in FIG. 30 are used to fix them.

  By tightening the nut 031f into the screw member 041f, the side portion 011fa and the side portion 011fb shown in FIG. 29 are deformed and hold down the screw member 041f from the left and right toward FIG.

  In the fixing device 001f shown in FIG. 29, each of the side portions 011fa and 011fb protrudes in a direction in which the screw member 041f is assumed to be present when the device is used (see FIGS. 7 and 8). Then, the side portions 011fa and 011fb are in contact with and held by the support portion 013f at the projecting portions 014fa and 014fb of the support portion 013f which are equally spaced in the circumferential direction. Further, the center line of the side portion parallel to the protruding portion in contact with each of the side portions and the circumferential direction of the support portion 013f at the position intersecting the center line of the protruding portion are substantially the same. Vertical.

  Therefore, when the nut 031 is screwed into the screw member 041 and tightened, the probability that the protrusions on the respective side portions come into contact with the shaft portions at equal intervals in the circumferential direction is improved. In that case, after that, the side portion is deformed so as to increase the contact portion with the screw member 041f, and the screw member 041f is tightened. Since the probability that the protrusions of the respective side portions come into contact with the portions of the screw member 041f at the same intervals in the circumferential direction is improved, the force applied to the respective side portions during the subsequent deformation of the side portions becomes uniform. Probability improves. Therefore, the probability that the side portions 011fa and 011fb are uniformly deformed is improved. Therefore, the probability that the shapes of the deformed side portions (not shown) of the side portions 011fa and 011fb in the fixed state become uniform is improved. The positional relationship between the hole 056 formed in the object 051 and the screw member 041f of the screw member 041 depends on the shape of the deformed side portions 011faz and 011fdz in the fixed state. The relationship is constant. Therefore, the fixing device 001g shown in FIG. 29 can improve the positional accuracy of the object 051 in the fixed state with respect to the screw member that is the object to be fixed. Further, since the screw member 041f is tightened on both sides of the screw member 041f, it is possible to suppress rattling between the attached object and the shaft.

  Therefore, when a nut is screwed onto the shaft of the screw member and tightened, the probability that the protrusions of the respective side parts come into contact with the shaft portions at equal intervals in the circumferential direction is improved. Then, after that, the shaft is tightened while deforming the side portion so as to increase the contact portion with the shaft. Since the probability that the protrusions on each side will contact the shaft portions at equal intervals in the circumferential direction is improved, the force applied to each side during subsequent deformation of the side will be even and The probability that the parts will be deformed uniformly is improved. Therefore, the probability that the shape of the deformed side portion in the fixed state becomes uniform is improved. The positional relationship between the hole formed in the object and the shaft of the screw member depends on the shape of the deformed side portion in the fixed state, and if this shape is uniform, the positional relationship becomes constant. . Therefore, the fixing device of the present embodiment can improve the positional accuracy of the object in the fixed state.
