Description

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

  When a relatively hard object is fixed to a fixed object having screws, nails, etc. (hereinafter referred to as “screws”) using a fixing auxiliary object such as a nut, the following operations are generally performed. Is called. First, a hole that is larger than the diameter of the insertion portion such as a screw is connected to the object and smaller than the portion of the fixed object to which the screw is connected, and the insertion portion such as a screw is passed through the hole. Here, the insertion portion refers to a portion that is scheduled to be inserted into an object such as a screw. Then, in that state, insert a screw or the like into the object, and screw until the gap between the part of the fixed object to which the screw or the like is connected and the object and the gap between the object and the fixing auxiliary object disappear. The insertion part such as is inserted into the hole of the fixing auxiliary object and fitted. For example, when the screw or the like is a screw, the screw thread is screwed into a screw groove formed on the side surface of the hole on a nut which is a fixing aid. Thus, the object is fixed to the screw or the like with a certain strength. Since there is no gap between the part of the object to be fixed in which an insertion part such as a screw is formed and the object, and no gap between the object and the fixing auxiliary object, the object, the fixing auxiliary object, and the fixed object are mutually It becomes a fixed state.

  However, a structure in which such an object, an object to be fixed, and a fixing auxiliary object are combined is often structurally weak. This is because, as described above, since the hole provided in the object is larger than the diameter of the insertion part such as a screw, a gap is formed between the inside of the hole of the object and the insertion part such as the screw. As described above, the part 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. Side slip occurs. The so-called rattling may occur due to the cause.

  As a method for solving the above problem, Patent Document 1 discloses the following technique. That is, a bent piece that slightly protrudes 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. Thereafter, the attachment body is brought into contact with the conductive attachment body, and the attachment body is tightly screwed to the hole of the conductive attachment body with a conductor screw inserted through the bent piece in the attachment 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 a molding material while deforming a tapered outer peripheral portion of a subframe / rigid collar for an automobile into an introduction hole. .

  In the technique disclosed in Patent Document 1, the bent piece is simply formed by bending a plate, and the attached body is formed by forcibly bending the bent piece by screwing the attached body tightly. Even if it can be attached, there is a problem that the attaching accuracy is inferior. This is because the way in which the bent pieces are bent is not constant.

  An object of the present invention is to provide a fixing device capable of suppressing the occurrence of rattling of an attached object and further improving the accuracy of the attachment position in attaching the object to an object to be fixed.

  The fixing device of the present invention includes an annular support portion having a predetermined symmetry axis and a predetermined degree of rotational symmetry, and a plurality of protrusions protruding from a protruding portion at a position having the rotational symmetry of the support portion. Side. Each of the plurality of side portions is located on the same side of the plane including the ring, and a center line of the side portion in a direction away from the projected portion with which the side portion is in contact, and the projected portion Is substantially perpendicular to the circumferential direction of the support portion at a position intersecting the center line. Each of the plurality of side portions further protrudes toward the inside of the ring.

  The fixing device of the present invention can suppress the occurrence of rattling of the attached object in attaching the object to the object to be fixed, and can further improve the attachment accuracy.

  FIG. 1 is a conceptual diagram showing a fixing device 001a having two side portions. The figure (a) is a top view, the figure (b) is a side view supposing the case where the direction of the arrow 091aa represented to the figure (a) is seen, and the figure (c) is the figure ( It is the side view supposing the case where the direction of arrow 091ab represented to a) was seen.

  The fixing device 001a includes a support part 013a, a side part 011aa, and a side part 011ab.

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

  Here, the “projected part” is a part of the boundary surface with the side part in the support part. The projecting portion is a boundary surface with the side portion of the assumed support portion assuming that the support portion in the vicinity of the projecting portion has a shape that is continuous with the surrounding support portion. Here, for example, if the surface of the support portion around the projecting portion is a flat surface, the shape continuous with the periphery means that the surface of the projecting portion is also a plane connected to the plane. is there. As will be described later, the support 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 assumed that the support portion and the side portion are in contact with the protruding portion, and the side portion is held by the support portion. These are the same in the following.

  A point 085a is a centroid of a figure formed by two centroids, that is, the centroid of the projecting portion 014aa and the centroid of the projecting portion 014ab.

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

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

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

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

  In the side portion 011aa, the bent portion 071aa protrudes in the direction of the side portion 011ab due to the bending in the bent portion 071aa.

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

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

  The material included in the side portions 011aa and 011ab may be a material that can be slightly deformed by pressing and is not too soft except at least in the vicinity of the protruding portion and in the vicinity of the end opposite to the protruding portion. preferable. The reason will be described later. In addition, it is more preferable that the material is less susceptible to alteration such as oxidation. Also, when considering the price, materials that are not too expensive are better. As such materials, typical candidates include aluminum, copper, lead, zinc, tin, alloys thereof, hard rubber, and resin.

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

  The support part 013a, the side part 011aa, and the side part 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 a position other than the end portion of the side portion.

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

  First, prepare a plate of materials.

  Then, the material plate is processed into the shape shown in FIG. FIG. 4A is a top view, and FIG. 4B is a cross-sectional view assuming a case of cutting along a line 084h shown in FIG. Cutting, cutting, die cutting, or the like can be used for processing when processing into a shape as shown in FIG.

  Next, in the parts represented by lines 084i and 084j shown in the same figure, the part from the line 084i to the arrow 098c and the part from the line 084j to the arrow 098d are bent in the direction of the arrow 098e, respectively. The bending at that time can be performed, for example, by pressing.

  As a result, the structure shown in FIG. 3 is obtained. The figure (a) is a top view, The figure (b) is sectional drawing supposing the case cut | disconnected by the line 084k represented to the figure (a).

  Next, in the part represented by line 084l and line 084m shown in the same figure, the part in the direction of arrow 098c from line 084l and the part in the direction of arrow 098d from line 084m are bent in the direction of arrow 098f, respectively. . The bending at that time can be performed, for example, by pressing.

  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 fixing device 001a will be described.

  FIG. 4 is a conceptual diagram showing a screw member 041, a nut 031, and an object 051 that is a fixing target, which are used in the description of the following operation example. 4A and 4B show the screw member 041, FIGS. 2C and 2D show the nut 031, and FIGS. 2E and 2F show the object 051. FIG. FIGS. 4A, 4C, and 4E are top views, and FIGS. 4B, 4D, and 5F are cross-sections taken along lines 084n, 084o, and 084p. FIG.

  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. The upper part of the shaft 042 toward the same figure (b) is a screw thread portion 044 in which a screw thread is formed on the side surface.

  The nut 031 includes a rectangular parallelepiped member 038. The member 038 is formed with a hole 036 that is formed by hollowing out a cylindrical shape having a diameter of 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 the thread portion of the thread portion 044 is formed.

  The target object 051 includes a rectangular parallelepiped member 058.

  The member 058 has a hole 056 formed by hollowing out a cylinder having a diameter 057 larger than the diameter 047 shown in FIG. 5A. A line 084c representing the central axis of the cylinder is perpendicular to the upper surface 062c. .

  FIG. 5 is a conceptual cross-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 to the shaft 042 of the screw member 041, the surfaces 061 a and 061 c which are the lower surfaces of the nut 031 come into contact with the surfaces 061 b and 061 d which are the upper surfaces 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 members of the object 051, respectively.

  Since the surface of each surface is not a completely flat surface but has some unevenness, the contact between the unevennesses is caused by contact. Therefore, even if a force is applied to the object in the direction of the arrow 094, for example, when the force is sufficiently small, the relative position of the object 051 with respect to the screw member 041 and the nut 031 is obtained by meshing the unevenness. Will 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, and there is a gap. 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 can vary. Therefore, when the unevenness is small, if the relative force with respect to the axis 042 applied to the object 051 in the direction of the arrow 094 is large, the unevenness is caused to ride on the object 051, and the direction of the arrow 094 with respect to the screw member 041 Variations in relative position to occur. Alternatively, when the force applied to the object 051 in the direction of the arrow 094 is large, the meshing unevenness may be crushed and the above fluctuation may occur. That is, the object 051 can move in the direction of the arrow 094.

  FIG. 6 is a conceptual cross-sectional view illustrating a state in which the object 051 has moved in the direction of the arrow 094 as a result of applying a force in the direction of the arrow 094 to the object 051 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 a part of a so-called rattling mechanism.

  FIGS. 7 to 11 are cross-sectional image diagrams illustrating 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 illustrating a state in which the shaft 042 of the screw member 041 is inserted into the hole 056 of the object 051 and the fixing device 001a is inserted into the hole 056. The insertion is performed such that the protruding portion 014aa and the protruding portion 014ab are directed upward in the same figure. Nut 031 has not yet been inserted into shaft 042.

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

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

  In the state shown in the figure, the surfaces 061a and 061c which are the lower surfaces of the nut 031 are in contact with the protruding portions 014aa and 014ab, respectively, but the side portions 011aa and 011ab are not 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 portion 011aa and the side portion 011ab are deformed when the protruding portions 014aa and 014b are pushed in the direction of the arrow 095 to 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 are moved in directions having components of directions of arrows 098a and 098b, respectively, and the deformed bent 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 parts 011aax and 011abx are pushed in the direction of the arrow 095. Accordingly, the bent portion 071aax pushes the side surface of the shaft 042 in a direction parallel to the direction of the arrow 098a, and the bent portion 071abx pushes the side surface of the shaft 042 in a direction including the component in the direction of the arrow 098b. The axis 042 hardly deforms in the direction including the component in either direction of the arrows 098a and 098b.

  Therefore, as shown in FIG. 10, both side portions are deformed to become side portions 011 aay and 011 aby. The contact area between the side portion 011 aay and the side surface of the shaft 042 and between the side portion 011 aby 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 a 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.

  When the nut 031 is further tightened, the side portion is further deformed, as shown in FIG. In the state shown in the figure, both side portions are further deformed to become side portions 011 aaz and 011 abz. 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 the 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 011 aaz and the side portion 011 abz are substantially equal, so that the central axis 084 c of the hole 056 and the central axis 084 a of the shaft 042 are substantially coincident with each other.

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

  In the fixing device 001a shown in FIG. 1, the side portions 011aa and 011ab protrude in a direction in which it is assumed that the shaft 042 of the screw member 041 is present when in use (see FIGS. 7 and 8). In addition, the side portion includes a plurality of side portions 011aa and 011ab. Then, the side part 011aa and the side part 011ab are held in contact with the projecting parts 014aa and 014ab at equal intervals in the circumferential direction of the support part 013. Further, the center line of the side part parallel to the direction away from the projecting part with which each side part is in contact and the circumferential direction of the support part 013 at the position where the center line of the projecting part intersects with the center line are substantially the same. It is vertical.

  Therefore, when the nut 031 is screwed and tightened to the shaft 042 of the screw member 041, the probability that the protruding portions on the respective side portions contact the shaft portions with the same interval in the circumferential direction is improved. Thereafter, the side portion is deformed so as to increase a contact portion with the shaft 042, and the shaft 042 is tightened. At this time, as described above, the probability that the protruding portions of the respective side portions come into contact with the portions of the shaft 042 having the same interval in the circumferential direction is improved. In that case, the way of applying the force applied to each side part in the subsequent deformation of the side parts becomes equal. Therefore, the probability that the side portions 011aa and 011ab are uniformly deformed is improved. Therefore, the probability that the shapes of the side parts 011 aaz and 011 abz after deformation in the fixed state are 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 shapes of the side parts 011aaz and 011abz after deformation in a fixed state. Becomes constant. Accordingly, the fixing device 001a illustrated 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 fixed object. Furthermore, since the shaft 042 is tightened on both sides of the shaft 042 at equal intervals, it is possible to suppress the occurrence of rattling between the attached object and the shaft.

  7 to 11 show a case where the fixing device is inserted into the hole 056 so that the support portion 013a shown in FIG. However, there may be a case where the fixing device is inserted into the hole so that the support portion 013a faces downward.

  FIG. 12 is an image view of a cross section assuming that the configuration shown in FIG. 11 is cut along line 082 shown in FIG. FIG. 12 illustrates only the shaft 042 and the two side portions of the screw member 041 illustrated 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 the case where the material with which a part is provided is soft.

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

  On the other hand, when the material provided in the side portion is soft, in the state shown in FIG. 11, the cross-sectional shape of the side portion is greatly deformed, resulting in shapes such as the side portions 011 aab and 011 abb.

  In the case of the shape shown in FIG. 5A, the contact area between the side portion 011aa and the side surface of the shaft 042 and the side portion 011aba and the side surface of the shaft 042 is small. Accordingly, when a relative force is applied to the side 011aaa or the side 011aba in the direction of the arrow 096 in the direction of the arrow 096, the side 011aaa and the side of the shaft 042, and the side 011aba and the side 011aba There may be a gap between the sides. Therefore, an excessively hard material may not be suitable for the material provided on the side portion from the above viewpoint.

  On the other hand, in the case of the shape shown in FIG. 5B, the contact area between the side portion 011 aab and the side surface of the shaft 042 and the side area 011 abb and the side surface of the shaft 042 is shown in FIG. Greater than. Furthermore, the surface of the side portion 011 aab that is 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 011 abb that is 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 is applied to the side 011 aab or the side 011 abb in the direction of the arrow 096 in the direction of the arrow 096, the side 011 aab and the side of the shaft 042, and the side 011 abb and the side 011 abb Deviation between the side surfaces is less likely to occur. However, if the material included in the side parts 011 aab and 011 abb is too soft, the material is deformed, so that the positional relationship between the side part 011 aab and the side surface of the shaft 042 and the side part 011 abb and the side surface of the shaft 042 varies. There is a case.

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

  Various variations can be assumed for the shape of the side portion.

  FIG. 13 is a conceptual diagram showing the bent side portion 011aa shown in FIG. FIG. 6A is a side view assuming a direction corresponding to the direction shown in FIG. 1B, and FIG. 6B shows the direction of the arrow 091c shown in FIG. It is the side view which assumed the case of seeing. The shape shown in FIG. 10A is also a cross-sectional shape assuming a case where the shape is cut by a line 084d shown in FIG.

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

  FIG. 14 is a conceptual diagram showing a bent side portion 011 aac having two bent portions. FIG. 6A is a side view assuming a direction corresponding to the direction shown in FIG. 1B, and FIG. 6B shows the direction of the arrow 091c shown in FIG. It is the side view which assumed the case of seeing. The shape shown in FIG. 10A is also a cross-sectional shape assuming a case where the shape is cut by a 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 time of insertion shown in FIG. 7), the direction of the axis 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 portion 011aad. FIG. 6A is a side view assuming a direction corresponding to the direction shown in FIG. 1B, and FIG. 6B shows the direction of the arrow 091c shown in FIG. It is the side view which assumed the case of seeing. The shape shown in FIG. 10A is a cross-sectional shape assuming a case where the shape is cut by a 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 time of insertion shown in FIG. 7), the direction of the shaft 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 illustrating a side portion 011aae including an exit portion. The figure (a) is a side view of the direction corresponding to the direction shown in FIG. 1 (b), and the figure (b) assumes the case where the direction of the arrow 091c shown in the figure (a) is seen. 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 time of insertion shown in FIG. 7), the direction of the shaft 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. And the side part 011aae is provided with the protrusion parts 073a and 073b in the part which protruded in cross-sectional shape.

  As a material for the protruding portions 073a and 073b, for example, resin or metal can be used. The protruding portions 073a and 073b can be created, for example, by joining a previously created protruding portion to a side portion before forming the protruding portion. Alternatively, when the material is a resin, a resin dissolved in a solvent may be attached to the side portion before forming the protruding portion, and then the solvent may be evaporated.

  In the figure, the protruding portions 073a and 073b having a cylindrical shape are shown, but the shape of the protruding portions is arbitrary.

  The protruding portions 073a and 073b are shown in FIG. 16B, which is the central portion of the side portion 011aae with respect to the axis of the screw member when used (when corresponding to the state shown in FIGS. 9 to 11). It acts as a guide to make the portion of the line 084g properly touch. The function of this guide will be described below.

  FIGS. 17 to 19 are top views (an illustration corresponding to the orientation of FIG. 1A) showing an operation example of the side portion 011aad that does not include the protruding portion. In the figure, only a part of the side portion 011 aad and the shaft 042 is shown.

  FIG. 17 shows a state before the side portion 011 aad contacts the shaft 042. From this state, when a nut (not shown) is tightened and a force is applied to the protruding portion 014i in the rearward direction, the protruding portion 089 is a portion protruding toward the axis of the side portion 011aad. Moves in the direction of arrow 098g with axis 042.

  Then, after contacting the position 077, for example, it is deformed (see FIG. 12B) like the side portion 011aaav shown in FIG. Here, the position 077 is a position of the shaft 042 that is assumed that the projecting portion 089 contacts the shaft 042 and further deforms as it is when the projecting portion 089 moves in the direction of the arrow 098g. In this case, the side portion 011 aav does not move relative to the shaft 042 in the direction of the arrow 097 even if a relative force with respect to the shaft 042 is applied to the side portion 011 aav in the direction of the arrow 097 to some extent.

  However, the protruding portion 089 of the side portion 011 aad shown in FIG. 17 may move in the direction of the arrow 098 g and shift after hitting the shaft 042. This may occur, for example, when the accuracy of attaching the side portion 011aad to a support portion (not shown) (see 013a in FIG. 1) is poor or when the material of the side portion 011aad is hard. In that case, the force in the direction of the arrow 098g shown in FIG. 17 is further applied, whereby the side portion 011aad shown in FIG. 17 is deformed at a position shifted after hitting the shaft 042. It looks like the side part 011aaw. In this case, when a relative force with respect to the axis 042 is applied to the side portion 011 aaw in the direction of the arrow 097, the side portion 011 aaw easily moves relative to the axis 042 in the direction of the 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 parts 011aaw shown in FIG. The operation will be described below.

  FIG. 20 illustrates a state in which the protruding portions 073a and 073b illustrated in FIG. In this state, the side portion 011 aae is in contact with the shaft 042 at both the protruding portion 073 a and the protruding portion 073 b, and is in a stable contact state in a direction parallel to the direction of the arrow 097. Therefore, the side portion 011aae is not easily displaced in a direction parallel to the direction of the arrow 097.

  Accordingly, the side portion 011aae is deformed in a state where it is properly in contact with the position 077, which is the position of the axis 042 that is assumed to be in contact, and becomes, for example, the side portion 011aaex shown in FIG. At this time, the protruding portions 073a and 073b shown in FIG. 20 are deformed along with the deformation of the side portion 011aaex like the protruding portions 073ax and 073bx shown in FIG.

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

  As a guide for deforming the side portion without shifting from the axis, a recess provided on the side portion as described below can be used instead of the protruding portions 073a and 073b shown in FIG.

  FIG. 22 is a conceptual diagram showing a side portion 011aaaf provided with a recess. The figure (a) is a side view of the direction corresponding to the direction shown in FIG. 1 (b), and the figure (b) assumes the case where the direction of the arrow 091c shown in the figure (a) is seen. It is a side view.

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

  Then, when the side portion 011aaaf is used (when inserted into the hole 056 in FIG. 7 like 011aa), the protruding portion 089f is assumed to face the axis (see the axis 042 in FIG. 7). Has been.

  Furthermore, a recess 075 is formed in the vicinity of the protruding portion 089f of the side portion 011aaaf.

  This figure shows a case where the vicinity of the recess 075 on the side opposite to the surface on which the recess 075 is provided of the side portion 011aaaf does not protrude. However, the shape in the vicinity of the depression 075 on the surface opposite to the surface on which the depression 075 is provided is arbitrary. For example, the vicinity of the dent 075 on the surface opposite to the surface on which the dent 075 is provided may protrude due to the influence of the dent 075.

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

  FIG. 23 is an image diagram illustrating a state in which the side portion 011aaaf illustrated 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 it is assumed that the center of the side portion 011aaaf is in contact with the shaft 042 and is deformed in the contacted state.

  In this state, the side portion 011aaaf 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 a direction parallel to the direction of the arrow 097. Accordingly, the side portion 011aaf is not easily displaced in a direction parallel to the direction of the arrow 097.

  Accordingly, the side part 011aaaf is deformed without being displaced in a state where it hits the position 077 that is the position of the axis 042 that is assumed to be in contact with the side part 011aaaf, for example, often becomes a side part 011aafx shown in FIG. . The depression 075 reduces the probability that the side part after deformation becomes, for example, the side part 011 aaw shown in FIG. 19 and rattling is likely to occur.

  The number of the side parts with which the fixing device of this embodiment is provided is arbitrary as long as it is plural.

  FIG. 25 is a conceptual diagram showing a fixing device 001b having four side portions. FIG. 4A is a top view, and FIG. 4B is a cross-sectional view assuming a case of cutting along line 083ba shown in FIG. Further, FIG. 6C is a cross-sectional view assuming a case of cutting along a line 083bc shown in FIG.

  The fixing device 001b includes a support part 013b and four side parts 011ba, 011bb, 011bc, and 011bd.

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

  A point 085c is the centroid of the figure formed by the centroids of the protruding portions 014ba, 014bb, 014bc, and 014bd.

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

  The angle formed between 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 is It is about 90 degrees.

  The angle formed between 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, which is the projected portion adjacent to the projected portion 014bc, and the point 085c is It is about 90 degrees.

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

  That is, the projecting portions 014ba, 014bb, 014bc, and 014bd are in positions having the fourth-order rotational symmetry in the annular support portion 013b having the fourth-order rotational symmetry. Further, the side parts 011ba, 011bb, 011bc and the side part 011bd are located on the same side of the plane including the ring.

  Positions of the side lines 011ba, 011bb, 011bc, and 011bd that intersect the center line of the projecting portion of the center line of the side portion parallel to the direction away from the projecting portion that the side portion is in contact with The angle formed with respect to the circumferential direction of the support portion 013b is about 90 degrees. These angles correspond to the angles formed by the arrows 091ad and 091ac in FIG.

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

  As the side portion, various types such as those shown in FIGS. 13, 14, 15, 16, and 22 can be used.

  26 is a cross-sectional concept showing a state (the 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. FIG. 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 of the longitudinal centerlines of the side portions 011baz and 011bcx. FIG. 26B is a cross-sectional view assuming a case where the side portions 011bbz and 011bd shown in FIG. 25 are cut along a plane including both of the longitudinal centerlines of the side portions 011bbz and 011bdx. is there. That is, it is assumed that FIG. 6B is a cross-section in a direction substantially perpendicular to FIG.

  As shown in FIG. 5A, 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. 5B, 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 parts 011ba, 011bb, 011bc, and 011bd protrude in the direction in which the shaft 042 of the screw member 041 is supposed to be present when in use (see FIGS. 7 and 8). Yes. The side portions 011ba, 011bb, 011bc, and 011bd are held in contact with the protruding portions 014ba, 014bb, 014bc, and 014bd at equal intervals in the circumferential direction of the support portion 013. The center line of the side portion parallel to the direction away from the projecting portion with which each side portion is in contact and the circumferential direction of the support portion 013b at the position where the center line of the projecting portion intersects with each other are substantially the same. It is vertical.

  Therefore, when the nut 031 is screwed and tightened to the shaft 042 of the screw member 041, the probability that the protruding portions on the respective sides come into contact with the equally spaced portions in the circumferential direction of the shaft 042 is improved. Thereafter, the side portion is deformed so as to increase a contact portion with the shaft 042, and the shaft 042 is tightened. As described above, since the probability that the protruding portions of the respective side portions come into contact with the portions of the shaft 042 that are equally spaced in the circumferential direction is improved, the force applied to each side portion during the subsequent deformation of the side portions is applied. Becomes 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 parts 011baz, 011bbz, 011bcz, and 011bdz after deformation in the fixed state are equalized 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 shapes of the side parts 011baz, 011bbz, 011bcz and 011bdz after deformation in the fixed state. If so, the positional relationship is constant. Therefore, the fixing device 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 fixed object. Further, since the shaft 042 is tightened on the equally spaced portion of the shaft 042, it is possible to suppress the occurrence of rattling between the attached object and the shaft.

  Further, when the fixing device 001b is used, the shaft is tightened by the four side portions arranged at equal intervals, so that the shaft 042 is compared with the case where the fixing device 001b is fixed only by the two opposite side portions. The relative position of the object is less likely to fluctuate. Here, the case where only two side portions are fixed is a case where it is assumed that there are no side portions 011bbz and 011bdz in FIG. 26, for example. The relative difficulty in changing the relative position of the object is obtained when a relative force is applied to the axis 042 with respect to the axis having any component in the directions of arrows 094a, 094b, 094c, and 094d. But it happens. That is, the fixing device 001b has an effect of making rattling more difficult compared to the case where the fixing device 001b is fixed only by two side portions.

  The number of side portions may be an odd number.

  FIG. 27 is a conceptual diagram showing a fixing device 001c having three side portions. (A) is a top view, and (b), (c), and (d) are cross-sectional views assuming a case where they are cut along lines 083ca, 083cb, and 083cc.

  The fixing device 001c includes a support part 013c and three side parts 011ca, 011cb, and 011cc.

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

  A point 085c is the center of gravity of the figure formed by the center of gravity of each of the protruding portions 014ca, 014cb, and 014cc.

  The angle formed between the straight line connecting the center of gravity of the projecting portion 014ca and the point 085c and the straight line connecting the center of gravity of the projecting portion 014cb that is the projecting portion adjacent to the projecting portion 014ca and the point 085c is About 120 degrees.

  The angle formed between the straight line connecting the center of gravity of the projecting portion 014cb and the point 085c and the straight line connecting the center of gravity of the projecting portion 014cc that is the projecting portion adjacent to the projecting portion 014cb and the point 085c is About 120 degrees.

  The angle formed between the straight line connecting the center of gravity of the projecting portion 014cc and the point 085c and the straight line connecting the center of gravity of the projecting portion 014ca that is the projecting portion adjacent to the projecting portion 014cc and the point 085c is About 120 degrees.

  That is, the projecting portions 014ca, 014cb, and 014cc are in a position having the tertiary rotational symmetry in the annular support portion 013c having the tertiary rotational symmetry. Further, the side parts 011ca, 011cb and the side part 011cc are located on the same side of the plane including the ring.

  The circumferential direction of the support portion 013c at the position where the center line of the side portion parallel to the direction away from the protruding portion with which each of the side portions 011ca, 011cb and 011cc is in contact with the center line of the protruding portion Is about 90 degrees. The angle corresponds to the angle formed by arrows 091ad and 091ac in FIG.

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

  As the side portion, various types such as those shown in FIGS. 13, 14, 15, 16, and 22 can be used.

  28 is a conceptual cross-sectional view showing a state (the 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. It 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 side portion 011caz and the center line of the shaft 042. FIG. 28B is a cross-sectional view assuming that the side portion 011 cb shown in FIG. 27 is cut along a plane including both the longitudinal center line of the side portion 011 cbz and the center line of the shaft 042. is there. FIG. 28C is a cross-sectional view assuming that the side portion 011cc shown in FIG. 27 is cut along a plane including both the center line in the longitudinal direction of the side portion 011ccz and the center line of the shaft 042. is there. That is, the figure (b) assumes that it is a section of the direction rotated 120 degrees when viewed from the top with respect to the figure (a), and the figure (c) is seen from the top. In this case, it is assumed that the cross section is in a direction rotated by 120 degrees.

  As shown in FIGS. 5A, 5B, and 5C, the object 051 has a side 011caz, 011cbz, and 011ccz, and when viewed from above, the axis 042 and the axis 042 from three directions every 120 degrees. It is fixed to the nut 031.

  In the fixing device 001c shown in FIG. 27, the side portions 011ca, 011cb, and 011cc protrude in a direction in which it is assumed that the shaft 042 of the screw member 041 is present when used (see FIGS. 7 and 8). The side portions 011ca, 011cb, and 011cc are held in contact with and held at the protruding portions 014ca, 014cb, and 014cc at equal intervals in the circumferential direction of the support portion 013. Then, the center line of the side part parallel to the direction away from the projecting part with which each side part is in contact and the circumferential direction of the support part 013c at the position intersecting the center line of the projecting part are substantially the same. It is vertical.

  Therefore, when the nut 031 is screwed and tightened to the shaft 042 of the screw member, the probability that the protruding portions of the respective side portions come into contact with the portions of the shaft having the same interval in the circumferential direction is improved. Thereafter, the side portion is deformed so as to increase a contact portion with the shaft 042, and the shaft 042 is tightened. In order to improve the probability that the protruding portions of the respective side portions come into contact with the axially spaced portions of the shaft 042 in the circumferential direction, the way in which the force applied to the respective side portions during the subsequent deformation of the side portions is equalized. become. Therefore, the probability that the side parts 011ca, 011cb, and 011cc are uniformly deformed is improved. Accordingly, the probability that the shapes of the side parts 011 caz, 011 cbz, and 011 ccz after deformation in the fixed state are 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 side part after deformation in the fixed state. If this shape is uniform, the positional relationship is constant. Accordingly, the fixing device 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 fixed object. Further, since the shaft 042 is tightened on the equally spaced portion of the shaft 042, it is possible to suppress the occurrence of rattling between the attached object and the shaft.

  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, so that the relative position with respect to the shaft 042 is compared with the case where it is restrained by only the two opposing side portions. The actual position is less likely to fluctuate. Here, the case where it is fixed only by two opposing sides is the case shown in FIG. 11, for example. This difficulty in fluctuation occurs even when a relative force is applied to the axis 042 with respect to the axis having components in any of the directions of arrows 094e, 094f and 094g shown in FIG. That is, the fixing device 001b has an effect of making rattling more difficult compared to the case where the fixing device 001b is fixed only by two side portions.

  The support portion is not circular and may have any shape.

  FIG. 29 is a conceptual diagram illustrating a fixing device 001f including a square support. The figure (a) is a top view, the figure (b) is a side view supposing the case where the direction of the arrow 091fa represented to the figure (a) is seen, and the figure (c) is the figure ( It is the side view supposing the case where the direction of arrow 091fb represented to a) was seen.

  The fixing device 001f includes a support part 013f and side parts 011fa and 011fb.

  The side portion 011fa and the support portion 013f are held in contact with each other at the protruding portion 014fa, and the side portion 011fb and the support portion 013f are held at the protruding portion 014fb.

  The point 085f is the center of gravity of the figure formed by the center of gravity of the protruding portion 014fa and the center of gravity of the protruding portion 014fb.

  The angle formed by the straight line connecting the center of gravity of the projecting portion 014fa and the point 085f and the straight line connecting the center of gravity of the projecting portion 014fb which is the projecting portion adjacent to the projecting portion 014fab and the point 085f is It is about 180 degrees.

  That is, the projecting portions 014fa and 014fb are in positions having secondary rotational symmetry in the annular support portion 013f having secondary rotational symmetry. Further, 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 part 011fb parallel to the direction away from the projected part 014fb with which the side part 011fb is in contact with the circumferential direction of the support part 013f at the position where it intersects the center line of the projected part 014fb 087 fb is about 90 degrees. Here, the circumferential direction is a direction parallel to the direction of the arrow 091 fd at a position where it intersects the center line of the projecting portion 014 fb.

  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 the center line of the protruding portion 014fa The angle formed is about 90 degrees.

  The side portion 011fa is bent at the bent portion 071fa so that the bent portion 071fa protrudes in the direction of the side portion 011fb.

  The side portion 011fb is bent at the bent portion 071fb so that the bent portion 071fb protrudes in the direction of the side portion 011fa.

As the side portion, various types such as those shown in FIGS. 13, 14, 15, 16, and 22 can be used. Moreover, you may provide four side parts.
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 description of the following usage example. (A), (c), (e), and (g) are top views, and (b), (d), (f), and (h) are (a), (c). It is sectional drawing supposing the case where each is cut | disconnected by line 084q, 084r, 084s, and 084t represented to (e) and (g). (A) and (b) show the screw member 041f, (c) and (d) show the nut 031f, (e) and (d) show the object 051f, (g) and (F) represents the spacer 065f.

  FIG. 31 is a cross-sectional view illustrating a state in which these members and the fixing device 001f illustrated in FIG. 30 are used and fixed.

  By tightening the nut 031f into the screw member 041f, the side member 011fa and the side portion 011fb shown in FIG. 29 are deformed, and the screw member 041f is held down 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 it is assumed that the screw member 041f is present during use (see FIGS. 7 and 8). The side portions 011fa and 011fb are in contact with and held by the support portions 013f at the protruding portions 014fa and 014fb where the circumferential distance of the support portion 013f is equal. Further, the center line of the side part parallel to the direction away from the projecting part with which each side part is in contact and the circumferential direction of the support part 013f at the position intersecting with the center line of the projecting part are approximately. It is vertical.

  Therefore, when the nut 031 is screwed onto the screw member 041 and tightened, the probability that the protruding portions on the side portions come into contact with the axially spaced axial portions in the circumferential direction is improved. In that case, the screw member 041f is tightened while the side portion is deformed to increase the contact portion with the screw member 041f. Since the probability that the protruding portions of the respective side portions come into contact with the portions of the screw members 041f that are equally spaced in the circumferential direction is improved, the manner in which the force applied to the respective side portions during the subsequent deformation of the side portions is equalized. Probability increases. Therefore, the probability that the side portions 011fa and 011fb are uniformly deformed is improved. Therefore, the probability that the shapes of the side parts after deformation in the fixed state of the side parts 011fa and 011fb (not shown) are equalized 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 shapes of the side portions 011faz and 011fdz after deformation in the fixed state. The relationship becomes constant. Accordingly, 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 fixed object. Furthermore, since the screw member 041f is tightened on both sides of the screw member 041f, the occurrence of rattling between the attached object and the shaft can be suppressed.
