Description

[Technical Field]

[0001] The present invention relates to a bearing device, a bearing member, and an assembling method of a bearing member that supports a superstructure such as a main girder in a substructure such as a pier of a bridge or the like. [Background technology]

[0002] Conventionally, there have been bearing devices that provide movable support in structures where vibration or relative displacement occurs, such as bridges, seismic isolation structures, or connections between fixed structures. Such bearing devices are disposed between an upper structure such as a main girder and a lower structure such as a bridge pier, and are capable of in-plane displacement at the interface between the upper shoe fixed to the upper structure and the lower shoe fixed to the lower structure, i.e., the sliding surface.

[0003] An example of a bearing member that constitutes the upper shoe of such a bearing device is shown in FIG. Specifically, the support member 90 that constitutes the upper shoe is equipped with a sliding member 91 made of synthetic resin that constitutes the sliding surface, and a retaining portion 92 that holds this sliding member 91. The coefficient of friction of the sliding member 91 is controlled to achieve the desired slidability. The sliding member 91 is integrated with the retaining portion 92 by bonding or the like.

[0004] In recent years, in order to more accurately control the sliding properties between the upper shoe and the lower shoe, the sliding member may be made of multiple sliding materials with different sliding properties, arranged, for example, in a grid pattern. The sliding materials with different sliding properties are made of a variety of materials, some of which are difficult to bond to the holding part that holds the sliding member. For this reason, sliding members using such sliding materials may be difficult or impossible to bond to the holding part. Using such sliding members that are difficult to bond to the holding part requires physical fixation, such as by screwing, to the holding part, which creates a problem of increased labor in the process of assembling the support member. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2003-301883 Summary of the Invention [Problem to be solved by the invention]

[0006] An object of the present invention is to provide a bearing device, a bearing member, and a method for assembling a bearing member that can be easily constructed even when a sliding member made of a material that is difficult to join to a holding portion is used. [Means for solving the problem]

[0007] This invention is characterized in that, in a bearing device having an upper shoe and a lower shoe arranged at each opposing portion of an upper structure and a lower structure, one of the upper shoe and the lower shoe is provided with a sliding member that forms a sliding surface and a retaining portion that retains the sliding member, the sliding member has a first sliding material and a second sliding material arranged adjacent to the first sliding material, the first sliding material is made of a material that can be joined to the retaining portion, and the second sliding material is made of a material different from the first sliding material, and at least one of the first sliding material and the second sliding material is provided with a regulating portion that regulates the separation of the second sliding material from the retaining portion.

[0008] The present invention also provides a bearing member in which one of the upper and lower shoes of the above-mentioned bearing device is provided with a sliding member that forms a sliding surface and a retaining portion that retains the sliding member, wherein the sliding member has a first sliding material and a second sliding material arranged adjacent to the first sliding material, the first sliding material being made of a material that can be joined to the retaining portion, and the second sliding material being made of a material different from the first sliding material, and at least one of the first sliding material and the second sliding material being provided with a regulating portion that regulates the separation of the second sliding material from the retaining portion.

[0009] The above-mentioned superstructure and substructure may be, for example, a bridge with the main girder as the superstructure and the pier as the substructure, a connecting corridor with a building as the substructure and a walkway connecting buildings as the superstructure, a roof structure with a column as the substructure and a truss roof as the superstructure, or a structure in an expansion structure with a building as the substructure and another building as the superstructure.

[0010] The bearing device is a movable bearing, and may be an omnidirectional movable bearing that can move in any direction within the plane of the sliding surface, or a one-way movable bearing that can move in one direction within the plane. The material constituting the first sliding member and the second sliding member includes, for example, a resin material having self-lubricating properties, a metal, and the like.

[0011] The above-mentioned joining includes, for example, bonding the first sliding material to the holding portion using an adhesive, adhering the first sliding material to the holding portion using a pressure-sensitive adhesive, welding or fusing the first sliding material to the holding portion, and magnetically attaching the first sliding material to the holding portion using a magnet.

[0012] The regulating portion includes, for example, a configuration in which a portion of the second sliding material is placed on the holding portion side of the first sliding material, and a portion of the first sliding material and a portion of the second sliding material abut against each other, thereby regulating the separation of the second sliding material from the holding portion; a configuration in which a recess is provided on one of the first sliding material and the second sliding material, and a protrusion that can fit into the recess is provided on the other of the first sliding material and the second sliding material, and the recess and the protrusion are fitted together to regulate the separation of the second sliding material from the holding portion; and a configuration in which the protrusion is provided on both the first sliding material and the second sliding material, and they are fitted together.

[0013] According to the present invention, even when a sliding member made of a material that is difficult to join to a holding portion is used, the bearing device and bearing member can be easily constructed. More specifically, in a bearing device provided with a sliding member that forms a sliding surface on one of an upper shoe and a lower shoe that are disposed at opposing portions of an upper structure and a lower structure, and a retaining portion that holds the sliding member, the sliding member has a first sliding member made of a material that can be bonded to the retaining portion, and a second sliding member disposed adjacent to the first sliding member and made of a material different from the first sliding member. Therefore, a bearing member having the desired sliding properties based on the sliding properties of the first sliding member and the second sliding member can be constructed. Furthermore, the first sliding member is bonded to the retaining portion.

[0014] In addition, the second sliding material is positioned adjacent to the first sliding material, which is made of a material that can be joined to the holding portion, and at least one of the first sliding material and the second sliding material is provided with a regulating portion that regulates the second sliding material's separation from the holding portion.

[0015] As a result, the second sliding member, which is disposed adjacent to the first sliding member joined to the retaining portion, among the sliding members that make up the sliding surface, is restricted from moving away from the retaining portion by the restricting portion provided on at least one of the first sliding member and the second sliding member. In other words, the second sliding member can be prevented from accidentally coming off the retaining portion.

[0016] In other words, by joining the first sliding member to the holding portion, the restriction portion can restrict the second sliding member from moving away from the holding portion, even if the second sliding member is not joined to the holding portion. Therefore, even if the second sliding member is made of a material that can be joined to the holding portion, or even if it is made of a material that cannot be joined, it can be used as a sliding member together with the first sliding member to efficiently construct a bearing device and a bearing member.

[0017] As an aspect of this invention, the sliding member may be provided with a pressing portion that extends toward another adjacent sliding member and presses the other sliding member toward the holding portion, and a pressed portion that is pressed by the pressing portion of the other adjacent sliding member.

[0018] The pressing portion may press the other sliding member toward the holding portion side, or may abut against the other sliding member without any gap. According to this invention, even if the second sliding member is difficult to join, it is possible to more reliably prevent it from falling off the holding portion.

[0019] Specifically, in adjacent sliding members that form a sliding surface, the pressed portion of one is pressed toward the holding portion by the pressing portion of the other. Therefore, for example, in a first sliding member among adjacent sliding members, the pressing portion presses the pressed portion of the adjacent second sliding member toward the holding portion. Furthermore, since the first sliding member can be joined to the holding portion as described above, by joining the first sliding member to the holding portion so that the pressed portion of the second sliding member is pressed by the pressing portion of the first sliding member, the second sliding member can be held in the holding portion while being restricted from moving away from the holding portion by the first sliding member. Therefore, even if the second sliding member is difficult to join, it is possible to more reliably prevent it from falling off the holding portion.

[0020] As another aspect of the present invention, the holding portion may be provided with a holding recess capable of accommodating a part of the sliding member. According to this invention, a portion of the sliding member can be accommodated in the holding recess, so that the sliding member can be held more reliably by the holding portion compared to, for example, a case where the sliding member is placed on the main surface of a plate-shaped holding portion.

[0021] In another aspect of the present invention, the holding recess may be provided with a locking portion at its end that can lock a part of the sliding member, and the sliding member may be provided with a locked portion that can lock with the locking portion. The locking portion may be, for example, a protruding piece formed by protruding a part of the holding recess, or may be a recess formed by depressing a part of the holding recess. The locked portion may be, for example, a protruding piece formed by protruding a part of the sliding member, or may be a recess formed by recessing a part of the sliding member.

[0022] According to this invention, the sliding member can be held more reliably by the holding portion. More specifically, for example, when a first sliding member and a second sliding member are arranged adjacent to each other and the second sliding member, which is difficult to join, is arranged at the end of the retaining recess, at least the end of the retaining recess of the second sliding member is no longer adjacent to the first sliding member, and therefore separation from the retaining recess, i.e., detachment, is not restricted. However, at the end of the retaining recess of the second sliding member arranged at the end of the retaining recess, the engaging portion of the second sliding member engages with the locking portion provided at the end of the retaining recess. Therefore, the end of the retaining recess of the second sliding member that is no longer adjacent to the first sliding member is restricted from separating from the retaining recess, thereby reliably preventing the second sliding member from accidentally detaching from the retaining recess.

[0023] In another aspect of the present invention, the sliding member may be configured in a circular shape, and the first sliding member and the second sliding member, which do not form the outer peripheral portion of the circular shape, may each be formed in the same shape. According to this invention, since the first sliding member and the second sliding member that do not form the circular outer peripheral portion are identical in shape, the ease of assembly when arranging them adjacent to each other to form a sliding member can be improved compared to when a sliding member is formed by assembling first sliding members and second sliding members formed in different shapes. Also, the first sliding member and the second sliding member formed in a predetermined shape are identical in shape. This allows for a common method of processing them into the predetermined shape, thereby improving the processability of the sliding member.

[0024] The present invention also provides a method for assembling a bearing member, in which one of an upper shoe and a lower shoe of a bearing device is provided with a sliding member constituting a sliding surface and a retaining portion for retaining the sliding member, the sliding member having a first sliding member and a second sliding member disposed adjacent to the first sliding member, the first sliding member being made of a material that can be joined to the retaining portion, the second sliding member being made of a material different from the first sliding member, and at least one of the first sliding member and the second sliding member being provided with a mechanism for restricting the separation of the second sliding member from the retaining portion. The method for assembling a support member that constitutes the sliding member includes a regulating portion, a pasting process in which the first sliding material and the second sliding material are juxtaposed and pasted to a temporary fixing sheet so as to cover the formation area of ​​the sliding member, a cutting process in which the first sliding material and the second sliding material pasted on the temporary fixing sheet are cut to the shape of the sliding member, an attachment process in which the first sliding material and the second sliding material held by the temporary fixing sheet are attached to the holding portion, and a sheet removal process in which the temporary fixing sheet is peeled off and removed from the first sliding material and the second sliding material attached to the holding portion.

[0025] With this invention, a support member can be constructed in which the sliding member is held in the holding portion with the sliding member cut to the desired shape, simply by arranging the first sliding material and the second sliding material that make up the sliding member on a temporary fixing sheet, cutting it to the shape of the sliding member, and attaching it to the holding recess. [Effects of the Invention]

[0026] According to the present invention, it is possible to provide a bearing device, a bearing member, and a method for assembling a bearing member that can be easily constructed even when a sliding member made of a material that is difficult to join to a holding portion is used.

[0030] 7(b) and 7(c) are cross-sectional views taken along the line AA in FIG. 4(a). In FIG. 2, a portion of the front side is cut away and shown by a broken line to facilitate understanding of the shapes of the elements constituting the sliding portion 30.

Along the height direction H, the side where the holder side wall 363 stands from the holder bottom surface 362 is defined as the lower side Hd, and the opposite side is defined as the upper side Hu. The first in-plane direction X is defined as the direction connecting the left and right in FIG. 4(a), and the second in-plane direction Y is defined as the direction connecting the top and bottom in FIG. 4(a).

[0032] The bearing device 1 is a seismic isolation device disposed between an upper structure and a lower structure to form a seismic isolation structure. This bearing device 1 is composed of an upper shoe 10 fixed to the upper structure and a lower shoe 20 fixed to the lower structure. The boundary surface between the upper shoe 10 and the lower shoe 20, i.e., the sliding surfaces (101, 201), slides, allowing support to be displaceable in the in-plane direction at the boundary surface (sliding surface), and the energy generated at the connection due to, for example, an earthquake or strong wind can be reduced compared to a rigid connection.

[0033] In detail, as shown in Figure 1, the support device 1 is composed of an upper shoe 10 fixed to the bottom surface of the upper structure (not shown) and a lower shoe 20 fixed to the top surface of the lower structure (not shown). First, we will explain the lower shoe 20. The lower shoe 20 is composed of a sole plate 21 fixed to the upper surface of the lower structure, and a slide plate 22 attached to the upper part of the sole plate 21. The upper surface of the slide plate 22 of the lower shoe 20 forms a lower shoe sliding surface 201 that slides against an upper shoe sliding surface 101 of the upper shoe 10, which will be described later. The slide plate 22 is composed of a stainless steel plate.

[0034] The upper shoe 10 is composed of a steel base pot 11 that is fixed to the bottom surface of the upper structure, and a sliding part 30 that is circular in plan view and is placed in a mounting recess 111 in the center of the bottom side of the base pot 11. As shown in FIG. 2, the sliding portion 30 mounted in the mounting recess 111 of the base pot 11 is made up of an elastic plate 31, a shim 32, a seal ring 33, a piston 34, and a bearing 35, in that order from the top.

[0035] The elastic plate 31 is a rubber plate having a circular shape in a plan view. The shim 32 is a thin plate made of fluororesin and formed in a circular shape in plan view with the same diameter as the elastic plate 31 . The seal ring 33 is a circular ring with a trapezoidal cross section, in which the outer side is a vertical surface and the inner side is an inclined surface that slopes downward toward the outer side, and its outer diameter is the same as that of the elastic plate 31 and the shim 32. The piston 34 is made of stainless steel and has a generally cylindrical shape, and has a circular recess 341 formed along the outer periphery of the upper surface, into which the seal ring 33 can be fitted.

[0036] The bearing 35, which functions as a support member, is composed of a bearing holder 36, which is circular in plan view and holds a slide bearing 37, a sliding member described later, on its bottom side, and the slide bearing 37, which is held in a holding recess 361 of the bearing holder 36.

[0037] The bearing holder 36 is a metal disk having a holding recess 361 on the bottom side that holds the slide bearing 37. The holding recess 361 is a circular recess that is shallower than the thickness of the slide bearing 37, and is formed by a holder bottom surface 362 that is the bottom surface of the bearing holder 36, and a holder side wall 363 that stands from the outer edge of the holder bottom surface 362 toward the downward side Hd (see FIG. 2).

[0038] The slide bearing 37, which is a sliding member, is formed in a circular shape in a plan view. A bottom surface 371 of the slide bearing 37 constitutes an upper shoe sliding surface 101 that slides against a lower shoe sliding surface 201, which is the surface of the slide plate 22 of the lower shoe 20. The slide bearing 37 is configured by arranging first sliding members 38 and second sliding members 39, which are smaller than the slide bearing 37, in a lattice pattern and staggered in order (see FIG. 2).

[0039] Next, the shapes of the first sliding member 38 and the second sliding member 39 will be described. Since the first sliding member 38 and the second sliding member 39 are made of different materials but have the same shape, the shape of the first sliding member 38 will be described in detail below, and a description of the second sliding member 39 will be omitted. Note that the reference numerals for each component of the second sliding member 39, which is formed in the same shape as the first sliding member 38, correspond to the reference numerals for each element of the first sliding member 38.

[0040] The first sliding member 38 is a rectangular member that is longer in the first in-plane direction X than in the second in-plane direction Y when viewed from the upper side Hu. As shown in FIG. 3 , the first sliding member 38 has a main body 381 and a first extension piece 382 and a second extension piece 383 that extend in opposite directions from the main body 381 in the first in-plane direction X, and has a generally rectangular S-shaped cross section when viewed from the second in-plane direction Y. The first sliding member 38 is made of a material that has a predetermined sliding property and can be adhered to the bearing holder 36. Examples of materials that can be used to form the first sliding member 38 include self-lubricating polyamide resin (PA) and polytetrafluoroethylene resin (PTFE), as well as other resins, metals, graphite, ceramics, etc.

[0041] The main body 381 is a rectangular block body that is longer in the second in-plane direction Y than in the first in-plane direction X when viewed from the upper side Hu, and is formed so that its height in the height direction H is approximately 1 / 3 of the length in the second in-plane direction Y. The height of the main body 381 in the height direction H is approximately twice the depth of the holding recess 361 of the bearing holder 36.

[0042] The first extension piece 382 is a plate-like body that extends a predetermined length in the first in-plane direction X from an upper side Hu above the central part of the height direction H of the main body portion 381, and is configured with a plate thickness that is approximately half the plate thickness of the main body portion 381.

[0043] The second extension piece 383 has approximately the same shape as the first extension piece 382, ​​but as shown in Figure 3, it extends in the opposite direction of the first in-plane direction X from a lower side Hd than the central part of the height direction H of the main body portion 381.

[0044] The first sliding member 38 configured in this manner has a square plate-like body in plan view on the upper surface side, which is composed of a main body portion 381 and a first extension piece 382, ​​and a square plate-like body in plan view on the lower surface side, which is composed of a main body portion 381 and a second extension piece 383.

[0045] Since the plate-like body is integrally configured to be shifted in the first in-plane direction X, the first sliding member 38 has step portions 384 on both the upper and lower surfaces thereof, which have a step shape in the height direction H, as shown in FIG. 3.

[0046] In addition, the second sliding member 39, which has the same shape as the first sliding member 38 composed of the above-mentioned elements, has different sliding properties from the first sliding member 38 and is made of a material that is difficult to adhere to the bearing holder 36 with an adhesive.

[0047] 4(a) and 4(b), the slide bearing 37 is configured by arranging a plurality of first sliding members 38 and second sliding members 39 configured in this manner in parallel both vertically and horizontally, i.e., the first sliding members 38 and second sliding members 39 are arranged in a lattice pattern, and the first sliding members 38 and second sliding members 39 are arranged in a staggered pattern. The slide bearing 37 made up of the first sliding members 38 and the second sliding members 39 is placed in a holding recess 361 of the bearing holder 36. The arrangement of the first sliding members 38 and second sliding members 39 that configure the slide bearing 37 and the attachment of the slide bearing 37 to the holding recess 361 will be described later.

[0048] Note that the bearing holder 36 may not be provided with the retaining recess 361, and the slide bearing 37 may be attached to the bottom surface of the bearing holder 36. Also, the bearing 35 may not be provided with the bearing holder 36, and the slide bearing 37 may be directly attached to the bottom surface of the piston 34. In this case, a retaining recess is provided in the bottom surface of the piston 34, and the slide bearing 37 is attached to the retaining recess.

[0049] The upper shoe 10 and the lower shoe 20 are formed by assembling the sliding part 30 including the bearing 35 configured in this manner into the mounting recess 111 of the base pot 11 in the above-mentioned order, and as shown in Figure 1, the upper shoe sliding surface 101 and the lower shoe sliding surface 201 are opposed to each other so that they can slide, and the support device 1 is formed by assembling the upper shoe 10 and the lower shoe 20.

[0050] In the bearing device 1, in which the upper shoe sliding surface 101 of the upper shoe 10 and the lower shoe sliding surface 201 of the lower shoe 20 slidably face each other, the load of the upper structure is supported by the lower structure. More specifically, the upper shoe sliding surface 101 of the upper shoe 10, to which the load of the upper structure acts, is in contact with the lower shoe sliding surface 201 of the lower shoe 20 provided on the lower structure with a contact pressure according to the load of the upper structure. In other words, the lower shoe sliding surface 201 of the lower shoe 20 supports the upper shoe sliding surface 101 with a bearing pressure according to the load of the upper structure.

[0051] Next, a method for assembling the bearing 35 in the bearing device 1 will be described with reference to FIGS. When assembling the bearing 35, more specifically, when forming the slide bearing 37 used in the bearing 35, a predetermined material is processed in advance by an appropriate method to form it into the above-mentioned shape.

[0052] Then, the plurality of first sliding members 38 and second sliding members 39 thus formed are aligned and attached to the temporary fixing sheet 50 so as to cover the formation area α of the slide bearing 37, which is the sliding member, as shown in Figure 6(a), to form the bearing sheet 37X (attaching process (step S1)).

[0053] In this case, the first sliding members 38 and the second sliding members 39 are arranged alternately in both the first in-plane direction X and the second in-plane direction Y, and are attached to a temporary fixing sheet 50 to form the bearing sheet 37X (see FIG. 6(a)). Specifically, one first sliding member 38 is arranged so that it is surrounded on all four sides by second sliding members 39, and one second sliding member 39 is arranged so that it is surrounded on all four sides by first sliding members 38.

[0054] Of the first sliding members 38 and second sliding members 39 arranged alternately in the first in-plane direction X, the first sliding member 38 is arranged on the side of the temporary fixing sheet 50 so that the second extending piece 383 extending from the main body portion 381 faces the first in-plane direction X relative to the main body portion 381. Therefore, the first extending piece 382 of the first sliding member 38 is arranged on the side away from the temporary fixing sheet 50, that is, on the upper side Hu, opposite the side on which the second extending piece 383 is arranged relative to the main body portion 381 in the first in-plane direction X. In other words, the first sliding member 38 is attached to the temporary fixing sheet 50 in such a manner that the main body portion 381 and the second extending piece 383 face the temporary fixing sheet 50, and the first extending piece 382 is spaced apart from the temporary fixing sheet 50, and the longitudinal direction of the first sliding member 38, which is formed in a rectangular shape in a plan view, faces the first in-plane direction X (see FIG. 6(b)).

[0055] Similarly, the second sliding member 39 is arranged on the side of the temporary fixing sheet 50 so that the second extending piece 393 extending from the main body 391 faces the first in-plane direction X relative to the main body 391. Therefore, the first extending piece 392 of the second sliding member 39 is arranged on the side opposite the side on which the second extending piece 393 is arranged relative to the main body 391 in the first in-plane direction X, and on the side away from the temporary fixing sheet 50, that is, on the upper side Hu. In other words, the second sliding member 39 is attached to the temporary fixing sheet 50 in such a manner that the main body 391 and the second extending piece 393 face the temporary fixing sheet 50, and the first extending piece 392 is away from the temporary fixing sheet 50, and the longitudinal direction of the second sliding member 39 formed in a rectangular shape in a plan view faces the first in-plane direction X (see FIG. 6(b)).

[0056] When the first sliding member 38 and the second sliding member 39 are arranged adjacent to the temporary fixing sheet 50 in the manner described above in the first in-plane direction X, the first extension piece 392 of the second sliding member 39 on the side where the second extension piece 383 is arranged relative to the main body portion 381 is arranged on the upper side Hu of the second extension piece 383, and the first extension piece 382 is arranged on the upper side Hu of the second extension piece 393 of the second sliding member 39 on the side where the first extension piece 382 is arranged relative to the main body portion 381.

[0057] In other words, the second extension piece 383 of the first sliding material 38 adjacent to the first in-plane direction X is positioned between the first extension piece 392 of the second sliding material 39 spaced apart from the temporary fixing sheet 50 and the temporary fixing sheet 50; in other words, the first extension piece 392 of the second sliding material 39 and the temporary fixing sheet 50 sandwich the second extension piece 383 of the first sliding material 38 in the height direction H.

[0058] Similarly, the second extending piece 393 of the second sliding material 39 adjacent to the first in-plane direction X is arranged between the first extending piece 392 of the second sliding material 39 spaced apart from the temporary fixing sheet 50 and the temporary fixing sheet 50; in other words, the first extending piece 392 of the second sliding material 39 and the temporary fixing sheet 50 sandwich the second extending piece 393 of the second sliding material 39 in the height direction H.

[0059] By arranging the first sliding material 38 and the second sliding material 39 so that they are adjacent to each other in the first in-plane direction X in this manner, the step portions 384 and 394 are overlapped and aligned so as to fit together in the first in-plane direction X, thereby forming a bearing sheet 37X that is attached to the temporary fixing sheet 50.

[0060] The above-mentioned temporary fixing sheet 50 uses an adhesive sheet or pressure-sensitive adhesive sheet having an attachment surface on one side that allows the attached first sliding material 38 and second sliding material 39 to be removably attached in the sheet removal process (step S4) described below.

[0061] In this way, the bearing sheet 37X formed by arranging multiple first sliding members 38 and second sliding members 39 as described above and attaching them to the temporary fixing sheet 50 is cut into a circle, which is the shape of the slide bearing 37, as shown in Figure 7(a) (cutting process (step S2)).

[0062] By this cutting process (step S2), the bearing sheet 37X composed of multiple first sliding members 38 and second sliding members 39 can be formed into a slide bearing 37 that has a circular shape in plan view that matches the shape of the retaining recess 361 of the bearing holder 36.

[0063] Furthermore, by this cutting process (step S2), among the plurality of first sliding members 38 and second sliding members 39, the first sliding members 38 and second sliding members 39 that form the outer peripheral portion of the slide bearing 37, which is circular in plan view, are cut into shapes different from the other first sliding members 38 and second sliding members 39 (see Figure 7(a)).

[0064] Then, as shown in FIG. 7(b), the first sliding member 38 and the second sliding member 39, which are still attached to the temporary fixing sheet 50, are attached to the holding recessed portion 361 (attaching step (step S3)). Furthermore, by this mounting process (step S3), the surfaces of the first sliding material 38 and the second sliding material 39 opposite to the surfaces attached to the temporary fixing sheet 50 in the above-mentioned attaching process (step S1) come into surface contact with the bearing holder 36.

[0065] At this time, the first sliding material 38 can be adhered to the bearing holder 36 by applying adhesive to the portion of the first sliding material 38 that comes into surface contact with the bearing holder 36, i.e., the upper surface side of the main body portion 381 and the first extension piece 382.

[0066] Note that adhesive may be applied to the first sliding member 38 and the portion of the first sliding member 38 facing the first sliding member 38 on the holder bottom surface 362 of the bearing holder 36. Note that although the second sliding member 39 is made of a material that is difficult to adhere to the bearing holder 36, there is no problem if adhesive is applied to it, so adhesive may be applied to the entire surface of the slide bearing 37 or the entire surface of the bearing holder 36.

[0067] By adhering the first sliding member 38 to the bearing holder 36, the movement of the second sliding member 39 relative to the bearing holder 36 is also restricted. Specifically, as shown in Figure 7(b), when the first sliding member 38 is adhered to the bearing holder 36, of the first sliding members 38 and the second sliding members 39 arranged alternately in the first in-plane direction X, the second extension piece 383 of the first sliding member 38 is positioned on the lower side Hd of the second extension piece 393 of the second sliding member 39 adjacent to it in the first in-plane direction X, and the step portion 384 and the step portion 394 are fitted together.

[0068] Therefore, the first sliding member 38 adhered to the bearing holder 36 restricts the movement of the second sliding member 39 adjacent to the bearing holder 36 in the first in-plane direction X in the first in-plane direction X and the movement in the height direction H away from the bearing holder 36. In other words, of the first sliding members 38 and second sliding members 39 arranged alternately in the first in-plane direction X, the second extending piece 383 of the first sliding member 38 functions as a restricting portion 41 that restricts the second sliding member 39 from moving away from the bearing holder 36.

[0069] In the above-mentioned mounting step (step S3), each of the first sliding members 38 and the second sliding members 39 may be mounted one by one in the holding recess 361. However, since a plurality of first sliding members 38 and second sliding members 39 are mounted in the holding recess 361 while being held by the temporary fixing sheet 50, a plurality of first sliding members 38 and second sliding members 39 can be mounted in the holding recess 361 efficiently and easily.

[0070] Then, the plurality of first sliding members 38 and second sliding members 39 are attached to the holding recess 361 together with the temporary fixing sheet 50, and the temporary fixing sheet 50 is peeled off and removed from the bonded first sliding members 38 and second sliding members 39 (sheet removal process (step S4)), thereby completing the assembly of the bearing 35, which is the support member.

[0071] In the slide bearing 37 that is formed into a circular shape in plan view by the cutting step (step S2) and the mounting step (step S3) and that is placed in the bearing holder 36, a second sliding member 39 that is not bonded to the bearing holder 36 may be placed on the outer periphery. In this case, for example, the second sliding member 39 on the outer periphery may be changed to a first sliding member 38 that is bonded to the bearing holder 36.

[0072] Alternatively, instead of changing the second sliding member 39 on the outer periphery to the first sliding member 38, for example, as shown in Fig. 7(c), a protruding piece 36x may be provided at the end of the bearing holder 36, protruding radially inward from the holder side wall 363 and biting into the second sliding member 39. This makes it possible to achieve the same effect as the above-mentioned restricting portion 41 for the second sliding member 39 arranged on the outer periphery and not bonded to the bearing holder 36.

[0073] In the above description, the first sliding members 38 and the second sliding members 39 are alternately arranged in both the first in-plane direction X and the second in-plane direction Y, thereby restricting movement of the second sliding members 39 in the first in-plane direction X on the bearing holder 36. However, for example, the first sliding members 38 and the second sliding members 39 in the above description may be arranged rotated 90 degrees around the height direction H as an axis. Alternatively, the cross-sectional shapes of the first sliding members 38 and the second sliding members 39 as viewed from the first in-plane direction X may be formed into a substantially rectangular S-shape as described above. This restricts movement of the second sliding members 39 in the second in-plane direction Y on the bearing holder 36.

[0074] In the above description, the first sliding members 38 and the second sliding members 39 are also arranged alternately in the second in-plane direction Y. However, for example, the first sliding members 38 and the second sliding members 39 adjacent to each other in the second in-plane direction Y may be arranged offset in the first in-plane direction X.

[0075] In this case, there is no particular limitation on the offset length in the first in-plane direction X of the first sliding members 38 and second sliding members 39 adjacent to each other in the second in-plane direction Y. For example, it may be half the length of the sides of the first sliding members 38 and second sliding members 39 that form a square in a planar view when attached, or it may even be the same length as the lengths of the sides. Note that if the offset length in the first in-plane direction X is the same as the lengths of the sides, rows in which only the first sliding members 38 or only the second sliding members 39 are arranged alternately in the first in-plane direction X and the second in-plane direction Y.

[0076] Furthermore, in the above description, the first sliding member 38 and the second sliding member 39 are configured so that the cross-sectional shape of the first sliding member 38 and the second sliding member 39 when viewed from the second in-plane direction Y is a substantially square S-shape. However, the shape is not limited to this and various shapes are possible as long as the movement of the second sliding member 39 in the direction away from the bearing holder 36 can be restricted.

[0077] (Second embodiment) Next, a bearing 35a including a slide bearing 37a in the second embodiment will be briefly described with reference to FIGS. In the following description, the same components as those described above will be denoted by the same reference numerals and the description thereof will be omitted.

[0078] Here, Fig. 8(a) is a schematic perspective view showing the upper surfaces of the first sliding member 38a and the second sliding member 39a, and Fig. 8(b) is a schematic perspective view showing the lower surfaces of the first sliding member 38a and the second sliding member 39a. Fig. 9(a) is a schematic cross-sectional view of the slide bearing 37a attached to the bearing holder 36, Fig. 9(b) is an enlarged view of part a in Fig. 9(a), and Fig. 9(c) is a schematic bottom view of the bearing 35a. Fig. 9(a) is a cross-sectional view taken along the line AA in Fig. 4(a) above.

[0079] A bearing 35a shown in FIGS. 8 and 9 has the same configuration as the bearing 35 in the first embodiment described above, except that it includes a slide bearing 37a instead of the slide bearing 37. The slide bearing 37a is formed in a circular shape in a plan view, similar to the slide bearing 37 in the first embodiment described above. The slide bearing 37a is configured by assembling a plurality of first sliding members 38a and a plurality of second sliding members 39a.

[0080] Next, the shapes of the first sliding member 38a and the second sliding member 39a will be described. Because the first sliding member 38a and the second sliding member 39a are made of different materials but have the same shape, the shape of the first sliding member 38a will be described in detail below, and a description of the second sliding member 39a will be omitted. Note that the reference numerals for each component of the second sliding member 39a, which is formed in the same shape as the first sliding member 38a, correspond to the reference numerals for each element of the first sliding member 38a.

[0081] The first sliding member 38a is a rectangular member that is longer in the first in-plane direction X than in the second in-plane direction Y when viewed from the upper side Hu. As shown in FIG. 9 , the first sliding member 38a has a substantially L-shaped cross section when viewed from the second in-plane direction Y, and is made up of a main body 381a and an extension piece 382a extending from the main body 381a to one side in the first in-plane direction X. Note that, like the first sliding member 38 in the first embodiment described above, the first sliding member 38a is made of a material that has a predetermined sliding property and can be adhered to the bearing holder 36. Note that the same material as the first sliding member 38 in the first embodiment described above can be used as the material for the first sliding member 38a.

[0082] The main body 381a is a block body having a square shape when viewed from the upper side Hu, and is formed so that its height in the height direction H is approximately half its length in the second in-plane direction Y. Note that, like the main body 381 in the first embodiment described above, the height of the main body 381a in the height direction H is approximately twice the depth of the holding recess 361 of the bearing holder 36.

[0083] The extension piece 382a is a plate-like body extending a predetermined length in the first in-plane direction X from a lower side Hd than the center part of the main body part 381a in the height direction H, and is configured with a plate thickness that is approximately half the plate thickness of the main body part 381. Specifically, the extension piece 382a extends a length that is approximately equal to the length of the main body part 381a in the first in-plane direction X and the second in-plane direction Y.

[0084] As described above, the first sliding member 38a includes an extension piece 382a extending from the main body 381 to one side in the first in-plane direction X. Therefore, the first sliding member 38a has, on its upper surface, one step portion 384a that has a step shape in the height direction H, as shown in FIG.

[0085] In addition, the second sliding member 39a, which has the same shape as the first sliding member 38a composed of the above-mentioned elements, has different sliding properties from the first sliding member 38a and is made of a material that is difficult to adhere to the bearing holder 36 with an adhesive.

[0086] The slide bearing 37a configured in this manner can be assembled as the bearing 35a, which is a support member, by carrying out the same assembly steps as in the first embodiment described above, that is, steps S1 to S4.

[0087] In addition, in the above-mentioned attachment step (step S1), the first sliding members 38a and the second sliding members 39a that constitute the slide bearing 37a of this embodiment are arranged so that the first sliding members 38a and the second sliding members 39a are alternately arranged in both the first in-plane direction X and the second in-plane direction Y, as in the first embodiment, and are attached to the temporary fixing sheet 50 to form the bearing sheet 37Xa.

[0088] At this time, of the first sliding members 38a and the second sliding members 39a arranged alternately in the first in-plane direction X, the first sliding member 38a is arranged on the side of the temporary fixing sheet 50 so that the extension piece 382a extending from the main body portion 381a faces the first in-plane direction X relative to the main body portion 381a. Therefore, the extension piece 382a of the first sliding member 38a is arranged on one side of the main body portion 381a in the first in-plane direction X, on the side of the temporary fixing sheet 50, that is, on the lower side Hd. In other words, the first sliding member 38a is attached to the temporary fixing sheet 50 in such a manner that the main body portion 381a and the extension piece 382a face the temporary fixing sheet 50, and the longitudinal direction of the first sliding member 38a, which is formed in a rectangular shape in a plan view, faces the first in-plane direction X.

[0089] Similarly, the second sliding member 39a is arranged on the side of the temporary fixing sheet 50 so that the extension piece 392a extending from the main body 391a faces the first in-plane direction X relative to the main body 391a. In this case, the extension piece 392a is arranged so that it faces the extension piece 382a of the adjacent first sliding member 38a in the first in-plane direction X. Therefore, the extension piece 392a of the second sliding member 39a is arranged on the other side of the main body 391a in the first in-plane direction X, away from the temporary fixing sheet 50, that is, on the upper side Hu. In other words, the second sliding member 39a is attached to the temporary fixing sheet 50 in such a manner that the main body 391a faces the temporary fixing sheet 50 and the extension piece 392a is away from the temporary fixing sheet 50, and the longitudinal direction of the second sliding member 39a, which is formed in a rectangular shape in a plan view, faces the first in-plane direction X (see FIG. 6(b)). In other words, the second sliding member 39a is attached in a vertically symmetrical orientation to the first sliding member 38a.

[0090] When the first sliding material 38a and the second sliding material 39a are arranged relative to the temporary fixing sheet 50 in the manner described above so as to be adjacent to each other in the first in-plane direction X, the extension piece 392a extending from the main body portion 391a is positioned on the upper side Hu of the extension piece 382a.

[0091] In this way, by arranging the first sliding material 38a and the second sliding material 39a so that they are adjacent to each other in the first in-plane direction X, the step portions 384a and 394a are overlapped and aligned so as to fit together in the first in-plane direction X, thereby forming a bearing sheet 37Xa that is attached to the temporary fixing sheet 50.

[0092] The first sliding member 38a and the second sliding member 39a arranged side by side in this manner are subjected to the above-described cutting step (step S2), and then to the attachment step (step S3). Note that in the attachment step (step S3), similarly to the first embodiment, adhesive is applied to the portions of the first sliding member 38a that come into surface contact with the bearing holder 36, i.e., the upper surfaces of the main body 381a and the extension piece 382a, so that the first sliding member 38a can be adhered to the bearing holder 36.

[0093] An adhesive may be applied to the portion of the holder bottom surface 362 of the bearing holder 36 that faces the extension piece 382a of the first sliding member 38a. Although the second sliding member 39a is made of a material that is difficult to adhere to the holder bottom surface 362, there is no problem if an adhesive is applied to it. Therefore, an adhesive may be applied to the entire surface of the slide bearing 37a or the entire surface of the holder bottom surface 362 of the bearing holder 36.

[0094] By performing this mounting process (step S3) and adhering the first sliding member 38a to the bearing holder 36, the movement of the second sliding member 39a relative to the bearing holder 36 is restricted, as in the first embodiment described above.

[0095] 9(b), of the first sliding members 38a and the second sliding members 39a arranged alternately in the first in-plane direction X, when the first sliding member 38a is adhered to the bearing holder 36, the extension piece 382a of the first sliding member 38a is arranged above the extension piece 392a of the second sliding member 39a adjacent to it in the first in-plane direction X, and the step portion 384a and the step portion 394a are fitted together. In other words, the second sliding member 39a is pressed against the retaining recess 361 of the bearing holder 36 by the extension piece 382a of the first sliding member 38 adjacent to it in the first in-plane direction X.

[0096] Therefore, the first sliding member 38a bonded to the bearing holder 36 restricts the movement of the second sliding member 39a adjacent to the bearing holder 36 in the first in-plane direction X in the first in-plane direction X and the movement in the height direction H away from the bearing holder 36. That is, of the first sliding members 38a and second sliding members 39a arranged alternately in the first in-plane direction X, the extension piece 382a of the first sliding member 38a functions as a restriction portion 41a that restricts the second sliding member 39a from moving away from the bearing holder 36, similar to the second extension piece 383 of the first sliding member 38 in the first embodiment described above (see FIG. 9(b)).

[0097] In this embodiment, the first sliding member 38a and the second sliding member 39a are configured in the shapes described above and are attached to the bearing holder 36 in a vertically symmetrical orientation. Therefore, as shown in Fig. 9(c), in the slide bearing 37b, rectangles and squares having different areas are alternately arranged in the first in-plane direction X.

[0098] This makes it possible to more easily adjust the coefficient of friction of the slide bearing 37a, which is made up of the first sliding member 38a and the second sliding member 39a. For example, the first sliding member 38a and the second sliding member 39a are formed with friction coefficients μA and μB such that μA > μB, and the friction coefficient of the first sliding member 38a is μA and the friction coefficient of the second sliding member 39a is μB.

[0099] In this way, in a slide bearing 37a composed of first sliding member 38a and second sliding member 39a with different friction coefficients, if the ratio of the occupied area of ​​first sliding member 38a with a larger friction coefficient to the total area is increased, the friction coefficient is adjusted to the larger side between μA and μB. Conversely, if the ratio of the occupied area of ​​first sliding member 38a with a larger friction coefficient is decreased, the friction coefficient of slide bearing 37a is adjusted to the smaller side between μA and μB.

[0100] In other words, by changing the occupancy ratio of the first sliding member 38a and the second sliding member 39a to the area of ​​the sliding bearing 37a, or, for example, by adjusting the extension length of the extension pieces 382a and 392a relative to the main body portions 381a and 391a, the friction coefficient of the sliding bearing 37a can be set arbitrarily between μA and μB.

[0101] In this way, by using the first sliding member 38a and the second sliding member 39a, which have different friction coefficients and different areas on the slide bearing 37a, the friction coefficient of the slide bearing 37a can be easily adjusted. Therefore, the slide bearing 37a can be formed with any friction coefficient depending on the conditions of use of the bearing device 1.

[0102] In the slide bearing 37a that is formed into a circular shape in plan view by the cutting step (step S2) and the attachment step (step S3) and that is placed in the bearing holder 36, a second sliding member 39a that is not bonded to the bearing holder 36 may be placed on the outer periphery. In this case, for example, the second sliding member 39a on the outer periphery may be changed to a first sliding member 38a that is bonded to the bearing holder 36.

[0103] Alternatively, the second sliding member 39a on the outer periphery may not be replaced with the first sliding member 38a, but the protruding piece 36x described in the first embodiment may be provided, thereby achieving the same effect as that described above.

[0104] In the above description, the first sliding members 38a and the second sliding members 39a are alternately arranged in both the first in-plane direction X and the second in-plane direction Y, thereby restricting movement of the second sliding member 39a in the first in-plane direction X on the bearing holder 36. However, for example, the first sliding members 38a and the second sliding members 39a in the above description may be arranged rotated 90 degrees around the height direction H as an axis. Alternatively, the cross-sectional shapes of the first sliding members 38a and the second sliding members 39a as viewed from the first in-plane direction X may be substantially L-shaped as described above. This restricts movement of the second sliding member 39a in the second in-plane direction Y on the bearing holder 36.

[0105] (Third embodiment) Next, a bearing 35b including a slide bearing 37b in the third embodiment will be briefly described with reference to FIGS.

[0106] Here, FIG. 10 is a schematic perspective view showing the underside of bearing holder 36b, FIG. 11(a) is a schematic perspective view showing the upper surface of first sliding member 38b, and FIG. 11(b) is a schematic perspective view showing the upper surface of second sliding member 39b. FIG. 12(a) is a schematic enlarged perspective view showing the upper surface of bearing seat 37Xb, and FIG. 12(b) is a schematic enlarged perspective view showing the lower surface of bearing seat 37Xb. FIG. 13(a) is a schematic cross-sectional view of slide bearing 37b attached to bearing holder 36b, FIG. 13(b) is an enlarged view of portion b in FIG. 13(a), and FIG. 13(c) is a schematic bottom view of bearing 35b. Note that in FIG. 11(a), a portion of the first sliding member 38b is cut away and indicated by a dashed line to facilitate understanding. FIG. 13(a) is a cross-sectional view corresponding to the arrow AA in FIG. 4(a).

[0107] The bearing 35b shown in Figures 10 to 13 has the same configuration as the bearing 35 in the first embodiment described above, except that it has a bearing holder 36b instead of the bearing holder 36 and a slide bearing 37b instead of the slide bearing 37.

[0108] The bearing holder 36b has substantially the same shape as the bearing holder 36, except that it is provided with a holder protrusion 364 and a holding recess 361b is provided instead of the holding recess 361. In this embodiment, the holder side wall 363 is formed to have a plate thickness that is about one-third of that of the first embodiment described above.

[0109] 10, the holder protrusion 364 is a generally annular shape that protrudes a predetermined length radially inward from the tip of the holder side wall 363. By providing such a holder protrusion 364, a holding recess 361b having a shape in which two circular recesses having different diameters are stacked on top of each other is formed inside the bearing holder 36b.

[0110] The slide bearing 37b is formed in a circular shape in a plan view, similar to the first embodiment etc. The slide bearing 37b is configured by assembling a plurality of first sliding members 38b and a plurality of second sliding members 39b.

[0111] Next, the shapes of the first sliding member 38b and the second sliding member 39b will be described. Because the first sliding member 38b and the second sliding member 39b are made of different materials but have the same shape, the shape of the first sliding member 38b will be described in detail below, and a description of the second sliding member 39b will be omitted. Note that the reference numerals for each component of the second sliding member 39b, which is formed in the same shape as the first sliding member 38b, correspond to the reference numerals for each element of the first sliding member 38b.

[0112] The first sliding member 38b is a member that has a substantially octagonal shape when viewed from the upper side Hu. As shown in FIG. 11 , the first sliding member 38b is integrally formed of a plate-like main body portion 381b that is square in plan view and an extension portion 382b that is provided on the lower side Hd of the main body portion 381a and is a plate-like body that is larger in plan view than the main body portion 381a. Similar to the first sliding member 38 in the first embodiment described above, the first sliding member 38b is formed of a material that has a predetermined sliding property and can be adhered to the bearing holder 36b. The same material as the first sliding member 38 described above can be used as the material for the first sliding member 38.

[0113] The main body 381b is a plate-like body having a predetermined thickness in the height direction H. Specifically, the main body 381b is a plate-like body formed so that the thickness in the height direction H is approximately ¼ of the length of the sides that form a square in plan view.

[0114] The extension portion 382b is a plate-like body having a thickness in the height direction H that is approximately equal to the thickness of the main body portion 381b. The extension portion 382b is a square plate-like body in a plan view, with sides longer than those of the main body portion 381b in both the first in-plane direction X and the second in-plane direction Y. The four corners of the extension portion 382b are formed by appropriate processing such as chamfering at a predetermined length, so that the extension portion 382b has a substantially octagonal shape in a plan view (see FIGS. 11(a) and 11(b)). The lengths of the sides of the extension portion 382b other than the corners are approximately equal to the lengths of the sides of the main body portion 381b in a plan view. Here, the surface of the extension portion 382b having the sides other than the corners is referred to as the outer peripheral surface 383b.

[0115] In this way, the first sliding member 38b, which is composed of a main body portion 381b and an extension portion 382b provided on the lower side Hd of the main body portion 381b and has a larger shape in a plan view than the main body portion 381b, has a cross-sectional shape in the first in-plane direction X and the second in-plane direction Y that is configured to be approximately an inverted T-shape, and has four step portions 384b on the upper surface side that have a step shape in the height direction H (see Figures 11(a) and 11(b)).

[0116] In addition, the second sliding member 39b, which has the same shape as the first sliding member 38b composed of the above-mentioned elements, has different sliding properties from the first sliding member 38b and is made of a material that is difficult to adhere to the bearing holder 36 with an adhesive.

[0117] The slide bearing 37b configured in this manner can be assembled as the bearing 35b, which is a support member, by carrying out the same assembly steps as in the first embodiment described above, that is, steps S1 to S4.

[0118] In the above-mentioned attachment step (step S1), the first sliding members 38b and the second sliding members 39b that constitute the slide bearing 37b of this embodiment are arranged alternately in both the first in-plane direction X and the second in-plane direction Y, as in the first embodiment, and attached to the temporary fixing sheet 50 to form the bearing sheet 37Xb.

[0119] In this case, of the first sliding members 38b and the second sliding members 39b arranged alternately in the first in-plane direction X, the first sliding member 38b has its extending portion 382b, which is formed integrally with its main body portion 381b, arranged on the side of the temporary fixing sheet 50 relative to the main body portion 381b, that is, on the lower side Hd. In other words, the first sliding member 38b is attached to the temporary fixing sheet 50 with its extending portion 382b arranged to face the temporary fixing sheet 50.

[0120] Similarly, the second sliding member 39b is disposed on the side of the temporary fixing sheet 50 so that the extending portion 392b, which is integral with the main body portion 391b, is disposed on the lower side Hd of the main body portion 391b. In other words, the second sliding member 39b is attached to the temporary fixing sheet 50 in such a manner that the main body portion 391b faces the temporary fixing sheet 50 (see FIG. 6(b)). In other words, the second sliding member 39b is attached in a vertically symmetrical orientation to the first sliding member 38b.

[0121] 12(a) and 12(b), the first sliding members 38b are arranged to surround the upper side Hu of one second sliding member 39b on all four sides. Specifically, the four first sliding members 38b are arranged so that one of the outer peripheral surfaces 383b faces the outer peripheral surface of the main body 391b of the second sliding member 39b.

[0122] By arranging the first sliding member 38b so as to surround the outer peripheral surface of the main body 391b in this manner, on the lower side Hd of one second sliding member 39b, the extension portion 392b is surrounded on all four sides by the first sliding member 38b. Specifically, the main body 381b of the first sliding member 38b is arranged so that one of the four outer peripheral surfaces faces the outer peripheral surface 393b of the extension portion 392b.

[0123] When the first sliding member 38b and the second sliding member 39b are arranged relative to the temporary fixing sheet 50 in the manner described above so as to be adjacent to each other in both the first in-plane direction X and the second in-plane direction Y, the extension portion 392b formed integrally with the main body portion 391b is arranged on the upper side Hu of the extension portion 382b.

[0124] In this way, by arranging the first sliding member 38b and the second sliding member 39b so that they are adjacent to each other in both the first in-plane direction X and the second in-plane direction Y, the first sliding member 38b and the second sliding member 39b are overlapped and lined up so that the step portions 384b and the step portions 394b provided in four locations on both the first sliding member 38b and the second sliding member 39b fit together in both the first in-plane direction X and the second in-plane direction Y, respectively, to form a bearing sheet 37Xb that is attached to the temporary fixing sheet 50.

[0125] The first sliding member 38b and the second sliding member 39b arranged side by side in this manner are subjected to a cutting step (step S2) and then an attachment step (step S3) in the same manner as in the first embodiment etc. In the attachment step (step S3), similar to the first embodiment etc., adhesive is applied to the portion of the first sliding member 38b that comes into surface contact with the bearing holder 36b, i.e., the upper surface side of the main body portion 381b, so that the first sliding member 38b can be adhered to the bearing holder 36b.

[0126] An adhesive may be applied to a portion of holder bottom surface 362 of bearing holder 36b that faces extension portion 382b of first sliding member 38b. Although second sliding member 39b is made of a material that is difficult to adhere to holder bottom surface 362, applying an adhesive does not cause any problems, so an adhesive may be applied to the entire surface of slide bearing 37b or the entire surface of holder bottom surface 362 of bearing holder 36b.

[0127] Furthermore, when performing this attachment step (step S3), the extension portion 392b of the second sliding member 39b can be inserted between the holder bottom surface 362 and the holder protrusion 364 at the end of the bearing holder 36b (see FIGS. 13(a) and 13(b)). As a result, the extension portion 392b is positioned and locked on the upper side Hu of the holder protrusion 364, and movement of the second sliding member 39b in the height direction H is restricted.

[0128] In the above description, the case where the second sliding member 39b is arranged at the end of the bearing holder 36b has been described in detail. Here, as described above, in the slide bearing 37b, the first sliding members 38b and the second sliding members 39b are arranged alternately in both the first in-plane direction X and the second in-plane direction Y, and therefore the first sliding member 38b is arranged at the end of the bearing holder 36b in some locations. Even in this case, as described above, the holder protrusion 364 and the extension portion 382b of the first sliding member 38b are engaged with each other, and movement of the first sliding member 38b in the height direction H is restricted.

[0129] By performing this attachment step (step S3), the first sliding member 38b is adhered to the bearing holder 36b. As a result, similar to the first embodiment, the movement of the second sliding member 39b relative to the bearing holder 36b is restricted.

[0130] 13(a) and 13(b), the first sliding members 38b and the second sliding members 39b are alternately arranged in both the first in-plane direction X and the second in-plane direction Y. When the first sliding member 38b is bonded to the bearing holder 36b, the extension portion 382b formed integrally with the main body portion 381b of the first sliding member 38b is disposed above the extension portion 392b of the second sliding member 39b adjacent thereto in the first in-plane direction X and the second in-plane direction Y. The step portion 384b is fitted into the step portion 394b. That is, the second sliding member 39b is pressed toward the retaining recess 361b of the bearing holder 36b by the extension portion 382b of the first sliding member 38b adjacent thereto in the first in-plane direction X and the second in-plane direction Y.

[0131] Therefore, the first sliding member 38b joined to the bearing holder 36b restricts the movement of the second sliding member 39b adjacent to the bearing holder 36b in the first in-plane direction X in the bearing holder 36b and the movement in the height direction H away from the bearing holder 36b. That is, of the first sliding members 38b and second sliding members 39b arranged alternately in the first in-plane direction X, the extending portion 382b of the first sliding member 38b functions as a restricting portion 41b that restricts the second sliding member 39b from moving away from the bearing holder 36b, similar to the second extending piece 383 in the first embodiment described above.

[0132] The above-described step portions 384b and 394b are provided on all four sides of the first sliding member 38b and the second sliding member 39b, i.e., in both the first in-plane direction X and the second in-plane direction Y. Therefore, the first sliding member 38b bonded to the bearing holder 36b restricts the movement of the second sliding member 39b adjacent to the first in-plane direction X and the second in-plane direction Y in the first in-plane direction X on the bearing holder 36b, and also restricts the movement of the second sliding member 39b in the second in-plane direction Y.

[0133] Furthermore, the first sliding member 38b and the second sliding member 39b in this embodiment are configured in the shapes described above and are attached to the bearing holder 36b in a vertically symmetrical orientation. Therefore, as shown in FIG. 13(c), squares and octagons with different areas are alternately arranged in both the first in-plane direction X and the second in-plane direction Y. This makes it easier to adjust the coefficient of friction of the slide bearing 37b, which is configured with the first sliding member 38b and the second sliding member 39b, as in the second embodiment.

[0134] The bearing device 1 configured in this manner has an upper shoe 10 and a lower shoe 20 disposed at opposing portions of the upper structure and the lower structure. One of the upper shoe 10 and the lower shoe 20 is provided with slide bearings 37, 37a, 37a constituting the upper shoe sliding surface 101 and bearing holders 36, 36b for holding the slide bearings 37, 37a, 37b. The slide bearings 37, 37a, 37b each have a first sliding member 38, 38a, 38b and a second sliding member 39, 39a, 39b disposed adjacent to the first sliding member 38, 38a, 38b. The first sliding members 38, 38a, 38b are made of a material that can be bonded to the bearing holders 36, 36b, and the second sliding members 39, 39a, 39b are made of a different material than the first sliding members 38, 38a, 38b. The first sliding members 38, 38a, 38b are provided with restricting portions 41, 41a, 41b that restrict the second sliding members 39, 39a, 39b from moving away from the bearing holders 36, 36b.

[0135] The bearings 35, 35a, 35b are provided on one of the upper shoe 10 and the lower shoe 20 of the bearing device 1 with slide bearings 37, 37a, 37b that form the upper shoe sliding surface 101 and bearing holders 36, 36b that hold the slide bearings 37, 37a, 37b. The slide bearings 37, 37a, 37b each have a first slide member 38, 38a, 38b and a second slide member 39, 39a, 39b arranged adjacent to the first slide members 38, 38a, 38b. The first slide members 38, 38a, 38b are made of a material that can be bonded to the bearing holders 36, 36b, and the second slide members 39, 39a, 39b are made of a different material from the first slide members 38, 38a, 38b. The first sliding members 38, 38a, 38b are provided with restricting portions 41, 41a, 41b that restrict the second sliding members 39, 39a, 39b from moving away from the bearing holders 36, 36b.

[0136] As a result, even when the slide bearings 37, 37a, 37b are made of a material that is difficult to join to the bearing holders 36, 36b, the support device 1 and the bearings 35, 35a, 35b can be easily constructed.

[0137] Specifically, in the bearing device 1, which is provided with slide bearings 37, 37a, 37b that form the upper shoe sliding surface 101 on one of the upper shoes 10 and the lower shoes 20 that are disposed at the opposing portions of the upper structure and the lower structure, and bearing holders 36, 36b that hold the slide bearings 37, 37a, 37b, the slide bearings 37, 37a, 37b have first slide members 38, 38a, 38b made of a material that can be joined to the bearing holders 36, 36b, and second slide members 39, 39a, 39b that are disposed adjacent to the first slide members 38, 38a, 38b and made of a different material than the first slide members 38, 38a, 38b. Therefore, it is possible to configure bearings 35, 35a, 35b that have the desired sliding characteristics based on the sliding characteristics of the first slide members 38, 38a, 38b and the sliding characteristics of the second slide members 39, 39a, 39b. The first sliding members 38, 38a, 38b are joined to the bearing holders 36, 36b.

[0138] In addition, the second sliding members 39, 39a, 39b are arranged adjacent to the first sliding members 38, 38a, 38b, which are made of a material that can be joined to the bearing holders 36, 36b, and the first sliding members 38, 38a, 38b are provided with regulating portions 41, 41a, 41b that regulate the separation of the second sliding members 39, 39a, 39b from the bearing holders 36, 36b.

[0139] As a result, of the slide bearings 37, 37a, 37b that make up the upper shoe sliding surface 101, the second sliding members 39, 39a, 39b that are arranged adjacent to the first sliding members 38, 38a, 38b that are joined to the bearing holders 36, 36b are restricted from moving away from the bearing holders 36, 36b by the restricting portions 41, 41a, 41b that are provided on the first sliding members 38, 38a, 38b. In other words, the second sliding members 39, 39a, 39b can be prevented from accidentally coming off the bearing holders 36, 36b.

[0140] In other words, by joining the first sliding members 38, 38a, 38b to the bearing holders 36, 36b, the restricting portions 41, 41a, 41b can restrict the second sliding members 39, 39a, 39b from moving away from the bearing holders 36, 36b, even if the second sliding members 39, 39a, 39b are not joined to the bearing holders 36, 36b. Therefore, the bearing device 1 and the bearings 35, 35a, 35b can be efficiently constructed by using the second sliding members 39, 39a, 39b together with the first sliding members 38, 38a, 38b as the slide bearings 37, 37a, 37b, not only when they are made of a material that can be joined to the bearing holders 36, 36b, but also when they are made of a material that cannot be joined.

[0141] In addition, the first sliding members 38, 38a, 38b and second sliding members 39, 39a, 39b that constitute the sliding bearings 37, 37a, 37b are provided with first extension pieces 382, ​​extension pieces 382a and extension portions 382b that extend toward the adjacent first sliding members 38, 38a, 38b or second sliding members 39, 39a, 39b and press the first sliding members 38, 38a, 38b or second sliding members 39, 39a, 39b toward the bearing holders 36, 36b, and first extension pieces 392, extension pieces 392a and extension portions 392b that are pressed by the first extension pieces 382, ​​extension pieces 382a and extension portions 382b of other adjacent sliding bearings 37, 37a, 37b.

[0142] This makes it possible to more reliably prevent the second sliding members 39, 39a, 39b, which are difficult to join, from falling off the bearing holders 36, 36b. Specifically, in the first sliding members 38, 38a, 38b and second sliding members 39, 39a, 39b that constitute the upper shoe sliding surface 101 and are adjacent to each other and that constitute the slide bearings 37, 37a, 37b, the first extension piece 392, extension piece 392a and extension portion 392b of the second sliding members 39, 39a, 39b are pressed toward the bearing holder 36, 36b by the first extension piece 382, ​​extension piece 382a and extension portion 382b of the first sliding members 38, 38a, 38b. Therefore, for example, of the adjacent slide bearings 37, 37a, 37b, in the first sliding members 38, 38a, 38b, the first extending piece 382, ​​extending piece 382a, and extending portion 382b press the first extending piece 392, extending piece 392a, and extending portion 392b of the adjacent second sliding members 39, 39a, 39b toward the bearing holders 36, 36b. As described above, the first sliding members 38, 38a, 38b can be joined to the bearing holders 36, 36b. Therefore, the first sliding members 38, 38a, 38b can be joined to the bearing holder 36, 36b so that the first extending pieces 392, 392a, and extending portions 392b of the second sliding members 39, 39a, 39b are pressed by the first extending pieces 382, ​​382a, and extending portions 382b of the first sliding members 38, 38a, 38b. This allows the second sliding members 39, 39a, 39b to be held in the bearing holder 36, 36b while being restricted from moving in a direction away from the bearing holder 36, 36b by the first sliding members 38, 38a, 38b. Therefore, even if the second sliding members 39, 39a, 39b are difficult to join, it is possible to more reliably prevent them from falling off the bearing holder 36, 36b.

[0143] Furthermore, since the bearing holders 36, 36b are provided with holding recesses 361, 361b capable of accommodating a portion of the slide bearings 37, 37a, 37b, the slide bearings 37, 37a, 37b can be more reliably held by the bearing holders 36, 36b than, for example, when the slide bearings 37, 37a, 37b are placed on the main surface of the plate-shaped bearing holders 36, 36b.

[0144] Further, the holding recess 361b is provided with a holder protrusion 364 capable of locking a part of the slide bearing 37b at its end, and the slide bearing 37b is provided with extensions 382b and 392b capable of locking with the holder protrusion 364. This allows the slide bearing 37b to be held more securely in the bearing holder 36b.

[0145] More specifically, for example, when the first and second sliding members 38b and 39b are adjacent to each other, if the second sliding member 39b, which is difficult to join, is positioned at the end of the holding recess 361b, at least the end of the holding recess 361b of the second sliding member 39b is no longer adjacent to the first sliding member 38b, and therefore separation from the holding recess 361b, i.e., detachment, is not restricted. However, at the end of the holding recess 361b of the second sliding member 39b positioned at the end of the holding recess 361b, the extension 392b of the second sliding member 39b engages with the holder protrusion 364 provided at the end of the holding recess 361b. Therefore, the end of the holding recess 361b of the second sliding member 39b, which is no longer adjacent to the first sliding member 38b, is restricted from separating from the holding recess 361b, reliably preventing the second sliding member 39b from accidentally detaching from the holding recess 361b.

[0146] The slide bearings 37, 37a, 37b are formed in a circular shape, and the first sliding members 38, 38a, 38b and second sliding members 39, 39a, 39b that do not form the circular outer periphery are formed in the same shape.

[0147] As a result, the first sliding members 38, 38a, 38b and the second sliding members 39, 39a, 39b, which do not form the circular outer peripheral portion, have the same shape. Therefore, the ease of assembly when configuring the slide bearings 37, 37a, 37b by arranging them adjacent to each other can be improved compared to configuring the slide bearings 37, 37a, 37b by assembling the first sliding members 38, 38a, 38b and the second sliding members 39, 39a, 39b formed in different shapes. Furthermore, the first sliding members 38, 38a, 38b and the second sliding members 39, 39a, 39b, which are formed in a predetermined shape, have the same shape. This allows a common method of processing them into the predetermined shape, thereby improving the processability of the slide bearings 37, 37a, 37b.

[0148] The bearings 35, 35a, 35b are provided with slide bearings 37, 37a, 37b that form the upper shoe sliding surface 101 and bearing holders 36, 36b that hold the slide bearings 37, 37a, 37b, on one of the upper shoe 10 and the lower shoe 20 of the bearing device 1. The slide bearings 37, 37a, 37b have first slide members 38, 38a, 38b and second slide members 39, 39a, 39b that are disposed adjacent to the first slide members 38, 38a, 38b. The first sliding members 38, 38a, 38b are made of a material that can be joined to the bearing holders 36, 36b, the second sliding members 39, 39a, 39b are made of a material different from that of the first sliding members 38, 38a, 38b, and the first sliding members 38, 38a, 38b are provided with restriction portions 41, 41a, 41b that restrict the second sliding members 39, 39a, 39b from separating from the bearing holders 36, 36b. An attachment process (step S1) is then performed in which the first sliding members 38, 38a, 38b and the second sliding members 39, 39a, 39b are aligned and attached to the temporary fixing sheet 50 so as to cover the formation regions α of the slide bearings 37, 37a, 37b. Next, a cutting process (step S2) is performed in which the first sliding members 38, 38a, 38b and the second sliding members 39, 39a, 39b attached to the temporary fixing sheet 50 are cut into the shape of the slide bearings 37, 37a, 37b. Subsequently, an attachment process (step S3) is performed in which the first sliding members 38, 38a, 38b and the second sliding members 39, 39a, 39b held by the temporary fixing sheet 50 are attached to the bearing holders 36, 36b. Then, a sheet removal process (step S4) is performed in which the temporary fixing sheet 50 is peeled off and removed from the first sliding members 38, 38a, 38b and the second sliding members 39, 39a, 39b attached to the bearing holders 36, 36b, to form the slide bearings 37, 37a, 37b.

[0149] As a result, by simply arranging and adhering the first sliding members 38, 38a, 38b and the second sliding members 39, 39a, 39b that make up the sliding bearings 37, 37a, 37b on the temporary fixing sheet 50, cutting them to the shape of the sliding bearings 37, 37a, 37b, and attaching them to the holding recesses 361, 361b, it is possible to form bearings 35, 35a, 35b in which the sliding bearings 37, 37a, 37b are held in the bearing holders 36, 36b with the sliding bearings 37, 37a, 37b cut to the desired shape.

[0151] For example, in the above explanation, the bearing device 1 is described as an omnidirectional movable bearing that can move in any direction within the plane of the sliding surface (101, 201) in the seismic isolation structure, but it may also be a one-way movable bearing that can move in one direction within the plane, or a fixed bearing that allows rotation within a horizontal plane.

[0152] The bearing device may also be used, for example, as a bearing device for supporting main girders on bridge piers, a bearing device for supporting walkways connecting buildings from the buildings, a bearing device for supporting truss roofs on columns, or a bearing device in an expansion structure connecting buildings.It can also be used as a seismic isolation bearing device installed between a building and its foundation.

[0153] Furthermore, the first extending piece 382, ​​the extending piece 382a, and the extending portion 382b that press the second sliding members 39, 39a, 39b toward the bearing holders 36, 36b may be configured to press the second sliding members 39, 39a, 39b toward the bearing holders 36, 36b, for example. Furthermore, they may be in contact with the second sliding members 39, 39a, 39b without any gap.

[0154] In addition, the materials constituting the first sliding members 38, 38a, 38b and the second sliding members 39, 39a, 39b may be various materials other than the self-lubricating polyamide resin (PA) or polytetrafluoroethylene resin (PTFE) as exemplified above, or other resins, metals, graphite, ceramics, etc.

[0155] Furthermore, in the above description, the first sliding members 38, 38a, 38b are bonded to the bearing holders 36, 36b using an adhesive. However, for example, the first sliding members 38, 38a, 38b and the bearing holders 36, 36b may be bonded to each other using an adhesive or may be welded or melted to each other. Furthermore, they may be magnetically attached to each other using a magnet.

[0156] Furthermore, the restricting portions 41, 41a, 41b that restrict the second sliding members 39, 39a, 39b from moving away from the bearing holders 36, 36b are the first extending pieces 382, ​​extending pieces 382a, and extending portions 382b that are provided on the first sliding members 38, 38a, 38b. However, a configuration similar to the restricting portions may be provided on the second sliding members 39, 39a, 39b, for example, or may be provided on both the first sliding members 38, 38a, 38b and the second sliding members 39, 39a, 39b.

[0157] In addition, the restricting portions 41, 41a, 41b are configured such that a portion of the second sliding member 39, 39a, 39b is disposed below the first sliding member 38, 38a, 38b. However, for example, a recess may be provided on one of the first sliding member 38, 38a, 38b and the second sliding member 39, 39a, 39b, and a protrusion that can fit into the recess may be provided on the other of the first sliding member 38, 38a, 38b and the second sliding member 39, 39a, 39b, and the recess and protrusion may be fitted together to restrict the separation of the second sliding member 39, 39a, 39b from the bearing holder 36, 36b. Furthermore, the protrusions may be provided on both the first sliding member 38, 38a, 38b and the second sliding member 39, 39a, 39b, and fitted together.

[0158] Furthermore, the cross-sectional shape of the first sliding members 38, 38a, 38b and the second sliding members 39, 39a, 39b may be other shapes such as a trapezoid or a parallelogram in addition to the above-mentioned angular S-shape, L-shape, and T-shape. Furthermore, the planar shapes of the first sliding members 38, 38a, 38b and the second sliding members 39, 39a, 39b in the assembled state are not limited to the shapes described above. For example, as shown in Fig. 14, a bearing 35c may be configured such that a disk-shaped first sliding member 38c or second sliding member 39c is disposed in the center, and first sliding members 38c or second sliding members 39c having a generally fan-shaped planar shape are disposed around it in the circumferential direction to form a single annular shape, with such annular shapes alternately disposed in the radial direction. Note that the single annular shape may be formed by both the first sliding member 38c and the second sliding member 39c.

[0159] In the above description, the slide bearings 37, 37a, 37b are configured using two types of first sliding members 38, 38a, 38b and second sliding members 39, 39a, 39b with different friction coefficients. However, the slide bearings 37, 37a, 37b may be configured using, for example, three or more types of sliding members with different friction coefficients.

[0160] In the above description, in the cutting step (step S2), the plurality of first sliding members 38, 38a, 38b and second sliding members 39, 39a, 39b attached to the temporary fixing sheet 50 are cut into the shapes of the slide bearings 37, 37a, 37b together with the temporary fixing sheet 50. However, only the plurality of first sliding members 38, 38a, 38b and second sliding members 39, 39a, 39b may be cut into the shapes of the slide bearings 37, 37a, 37b. Furthermore, the slide bearings 37, 37a, 37b may be formed in various shapes such as elliptical, oval, square, etc., in addition to circular shapes. [Explanation of symbols]
