Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, in an adhesion jig, when a clearance is provided in a holding portion that holds a member to ensure workability, when the member is crimped to the stabilizer body, the member deforms and a part of it enters and spreads into the clearance, resulting in a decrease in the surface pressure on the stabilizer body. On the other hand, when a space equivalent to the size of the member is formed as the holding portion, since there is no clearance, it takes time to attach and detach the member to and from the adhesion jig, or it may not be possible to attach or detach it appropriately, which may reduce workability. The adhesion jig is required to ensure the surface pressure of each member of the bush against the main body portion of the stabilizer during adhesion, and to prevent a decrease in workability when installing the member on the jig or when removing the jig after adhesion.

MODE FOR CARRYING OUT THE INVENTION

[0024] Hereinafter, embodiments for carrying out the present invention (hereinafter referred to as "embodiments") will be described with reference to the accompanying drawings. It should be noted that the drawings are schematic, and the relationship between the thickness and width of each part, the ratio of the thickness of each part, etc. may be different from the actual ones, and there may be parts where the dimensional relationship and ratio are different between the drawings.

[0025] (Embodiment 1) FIG. 1 is a perspective view showing an example of a stabilizer manufactured in Embodiment 1 of the present invention. FIG. 2 is a view showing the configuration near the bush member in the stabilizer shown in FIG. 1. The stabilizer 1 is formed of metal or various fibers (for example, carbon fibers). The stabilizer 1 has a main body portion 2 whose both ends are bent and whose central portion extends linearly, and a bush member 3 attached to the main body portion 2.

[0026] The main body portion 2 extends in a columnar shape, for example, a cylindrical shape, and both ends are bent. The main body portion 2 may be solid or hollow.

[0027] For example, when the stabilizer 1 is provided in an automobile, one end is connected to one of the suspensions whose ends are arranged left and right, and the other end is connected to the other suspension. At this time, each end is fixed to the suspension through a through hole. Further, the stabilizer 1 is also fixed to the vehicle body through the bush member 3.

[0028] The stabilizer 1 is manufactured by processing a base material. For example, after bending a columnar base material, both ends are pressed into a flat shape, and through holes are formed at each end.

[0029] The bush member 3 has a bush 31 and a bracket 32. The bracket 32 is attached to the vehicle body via a screw or the like and supports the main body portion 2 via the bush 31.

[0030] The bush 31 is formed using an elastic material such as rubber or an elastic resin, and functions as a damping member for damping vibrations of the stabilizer 1 transmitted from the road surface or the like. The bush 31 is composed of two members (a first member 301 and a second member 302). The bush 31 is formed by sandwiching the main body portion 2 between the first member 301 and the second member 302 and adhering to the main body portion 2.

[0031] Next, an adhesion process for adhering the bush 31 described above to the main body 2 will be described with reference to FIG. 3. FIG. 3 is a flowchart showing the flow of the bush adhesion process according to the first embodiment.

[0032] First, an adhesive is applied to the first member 301 and the second member 302 (step S101: adhesive application step). In step S101, the adhesive is applied to the main body adhesion surfaces of the first member 301 and the second member 302. After the adhesive is applied to the first member 301 and the second member 302, a drying process is performed. Thereafter, the first member 301 and the second member 302 are set in an adhesion jig. The adhesion jig will be described later.

[0033] After the adhesive is applied, a heat treatment is performed on the adhesion portion of the bush 31 of the main body 2 (step S102: heating step). In the heat treatment, for example, a region including the bush 31 adhesion portion of the main body 2 is heated by an IH coil. In the heat treatment, the main body 2 is heated, for example, by heating for about several tens of seconds. The temperature of the heat treatment is appropriately set according to the types of the bush 31 and the adhesive. Note that before the heat treatment, a surface treatment for improving the adhesiveness to the main body 2 may be performed by plasma treatment.

[0034] Thereafter, the first member 301 and the second member 302 are set in an adhesion jig, and a bush assembly process is performed on the main body 2 (step S103: bush assembly process). In the bush assembly process, a load for pressing the first member 301 and the second member 302 against the main body 2 is applied by an adhesion jig. Note that the heating step and the bush assembly step may be in the reverse order.

[0035] After an adhesion jig is assembled to the main body 2, a crimping and holding process for adhering the bush 31 to the main body 2 is performed (step S104: crimping and holding process). In the crimping and holding process, for example, it is held in the assembled state for a time when the adhesion is completed. At this time, the main body 2 and the bush 31 are adhered by the pressure and the heat of the main body 2. Examples of the adhesion mode at this time include vulcanization adhesion.

[0036] Thereafter, by removing the bonding jig from the bush 31, a stabilizer 1 with the bush 31 fixed to the main body 2 is obtained. A bracket 32 is attached to the bush 31.

[0037] Subsequently, with reference to FIGS. 4 to 10, the bonding jig will be described. FIGS. 4, 6, 7, and 9 are plan views for explaining the configuration of the bonding jig for bonding the bush to the main body in Embodiment 1. FIGS. 5, 8, and 10 are perspective views for explaining the configuration of the bonding jig for bonding the bush to the main body in Embodiment 1. FIGS. 4 to 6 show only the bonding jig. FIGS. 7 to 10 show the bonding jig with the first and second members of the bush mounted thereon.

[0038] The bonding jig 10 includes a first bonding member 11 and a second bonding member 12. The bonding jig 10 presses the first member 301 and the second member 302 against the main body 2 by covering the first bonding member 11 with the second bonding member 12. At this time, for example, an air cylinder is used to pressurize the first bonding member 11 and the second bonding member 12.

[0039] The first bonding member 11 has a bottom surface portion 111 on which the first member 301 is placed, a first wall portion 112 and a second wall portion 113 erected from both end portions of the bottom surface portion 111 with respect to the bottom surface portion 111, and coil springs 114 that bias the wall portions in a direction away from the bottom surface portion 111, respectively.

[0040] The second bonding member 12 has a main body portion 121 that holds the second member 302, and a first wall portion 122 and a second wall portion 123 erected from both end portions of the main body portion 121 with respect to the main body portion 121.

[0041] Here, in a state where the first adhesive member 11 is not receiving the load from the second adhesive member 12, let the distance between the outer walls of the first wall portion 112 and the second wall portion 113 be d1, the distance between the inner walls of the first wall portion 122 and the second wall portion 123 be d2, the distance between the inner walls of the first wall portion 112 and the second wall portion 113 be d3, and the width of the first member 301 be d4 (see FIG. 7). The distance d1 is larger than the distance d2, and the distance d3 is larger than the width d4. Also, the difference (d1 - d2) between the distance d1 and the distance d2 is set to be approximately the same as the difference (d3 - d4) between the distance d3 and the width d4. By making the difference (d1 - d2) and the difference (d3 - d4) approximately the same, when the second adhesive member 12 is placed over the first adhesive member 11, the distance between the inner walls of the first wall portion 112 and the second wall portion 113 is made approximately the same as the width d4, and the first wall portion 112 and the second wall portion 113 are brought into contact or press - contact with the first member 301.

[0042] In the bonding jig 10, when the second adhesive member 12 is placed over the first adhesive member 11 (see FIG. 4), the first wall portion 122 and the second wall portion 123 abut against the first wall portion 112 and the second wall portion 113 respectively, and move the first wall portion 112 and the second wall portion 113 toward the bottom surface portion 111 side. As a result, the distance between the first wall portion 112 and the second wall portion 113 (corresponding to the distance d3) is reduced. Note that the abutting portions of the first wall portions 112, 122 and the second wall portions 113, 123 have a tapered shape with chamfered corners, and when abutting, the first wall portion 112 and the second wall portion 113 can be moved while being accommodated in the second adhesive member 12. Also, this tapered shape may be formed on at least one of the wall portions that contact each other. For example, if one of the first wall portions 112, 122 has a tapered shape, it can operate smoothly.

[0043] With the first member 301 attached to the first adhesive member 11 and the second member 302 attached to the second adhesive member 12 (see FIGS. 7 and 8), when the main body 2 is disposed between the first member 301 and the second member 302 and the second adhesive member 12 is placed over the first adhesive member 11, the main body 2, the first member 301, and the second member 302 come into contact, and the first member 301 is sandwiched and held by the first wall portion 112 and the second wall portion 113 (see FIGS. 9 and 10). At this time, immediately after the first member 301 and the second member 302 come into contact, the first member 301 is sandwiched by the first wall portion 112 and the second wall portion 113, but the contact between the first member 301 and the second member 302 and the clamping of the first member 301 by the first wall portion 112 and the second wall portion 113 may be in reverse order or may occur simultaneously.

[0044] At this time, by sandwiching and holding the first member 301 by the first wall portion 112 and the second wall portion 113, the first member 301 can be positioned. Further, since the movement of the first wall portion 112 and the second wall portion 113 is due to the contact of the second adhesive member 12, the relative positional relationship between the positions of the first wall portion 112 and the second wall portion 113 and the position of the second adhesive member 12 can be fixed. Thereby, while suppressing the relative displacement between the position of the first member 301 held by the first adhesive member 11 and the position of the second member 302 held by the second adhesive member 12, it is possible to press-bond the main body 2.

[0045] Also, after the bush 31 is adhered to the main body 2, when the second adhesive member 12 is removed from the first adhesive member 11, the first wall portion 112 and the second wall portion 113 move away from each other in the direction of the biasing force of the coil spring 114, and a gap is generated between the first wall portion 112 and the second wall portion 113 and the first member 301. Due to the generation of this gap, the first member 301 can be easily removed from the first adhesive member 11.

[0046] The coil spring 114 is included in a switching mechanism that switches between a first state in which a gap is formed between a part of a side surface of the first member 301 that is continuous with the crimping surface of the first member 301 and the second member 302 and the first adhesive member 11 in the space where the first adhesive member 11 holds the first member 301, and a second state in which the gap is filled to regulate the position of the first member 301. In Embodiment 1, the gap between the first member 301 and the first adhesive member 11 is filled by the movement of the first wall portion 112 and the second wall portion 113.

[0047] In the present Embodiment 1, when attaching and detaching the constituent members of the bush 31 to each adhesive member, a gap is provided between the first wall portion 112 and the second wall portion 113 and the first member 301 to ensure workability. When crimping the first member 301 and the second member 302 to the main body portion 2, the first member 301 is sandwiched by the first wall portion 112 and the second wall portion 113 to fix the position. Therefore, crimping can be performed while suppressing displacement of the crimping surface with respect to the main body portion 2 of the first member 301 and the second member 302. According to the present Embodiment 1, it is possible to surely perform the crimping of the bush 31 to the main body portion 2 while suppressing a decrease in workability.

[0048] In addition, in Embodiment 1, if the first wall portion 112 and the second wall portion 113 can move in a direction away from each other due to their own weight, a configuration without the coil spring 114 can be adopted.

[0049] Also, in Embodiment 1, an example of applying an adhesive to the bush 31 has been described. However, the adhesive may be applied to the main body portion 2, or the adhesive may be applied to the bush 31 and the main body portion 2 respectively.

[0050] (Embodiment 2) Next, Embodiment 2 of the present invention will be described with reference to FIG. 11. FIG. 11 is a plan view for explaining the configuration of an adhesive jig for adhering a bush to a main body portion in Embodiment 2. The same parts as those of the adhesive jig 10 according to Embodiment 1 are denoted by the same reference numerals.

[0051] The bonding jig 10A according to Embodiment 2 includes a first bonding member 11A and a second bonding member 12A. The bonding jig 10A presses the first member 301 and the second member 302 against the main body 2 by covering the first bonding member 11A with the second bonding member 12A.

[0052] The first bonding member 11A has a bottom surface portion 111 on which the first member 301 is placed, a first wall portion 112 and a second wall portion 113 that are erected from both ends of the bottom surface portion 111 with respect to the bottom surface portion 111, and a coil spring 114 that biases in a direction away from the bottom surface portion 111. In the first bonding member 11A, holes 112a and 113a are respectively formed by drilling from the ends on the side opposite to the side connected to the bottom surface portion 111 in the first wall portion 112 and the second wall portion 113. The holes 112a and 113a each have a hole shape that extends obliquely toward the outer wall side.

[0053] The second bonding member 12A has a main body portion 124 that holds the second member 302, and a first pin 125 and a second pin 126 that extend from both ends of the main body portion 124. The first pin 125 and the second pin 126 extend in opposite directions according to the inclination of the holes 112a and 113a. In Embodiment 2, the first pin 125, the second pin 126, and the holes 112a and 113a constitute a switching mechanism.

[0054] Here, in a state where the first bonding member 11A is not receiving the load from the second bonding member 12A, the distance (corresponding to the distance d3) between the inner wall of the first wall portion 112 and the inner wall of the second wall portion 113 is larger than the width of the first member 301 (the distance d4 shown in FIG. 7), and is set such that the distance between the inner wall of the first wall portion 112 and the inner wall of the second wall portion 113 becomes approximately the same as the width d4 when the second bonding member 12A is placed on the first bonding member 11A.

[0055] Next, when using the jig 10A, when the second adhesive member 12A is placed over the first adhesive member 11A, the first pin 125 and the second pin 126 are inserted into the hole portions 112a and 113a, respectively. As the first pin 125 and the second pin 126 slide against the wall surfaces of the hole portions 112a and 113a, the first wall portion 112 and the second wall portion 113 are moved toward the bottom surface portion 111 side. As a result, the distance between the first wall portion 112 and the second wall portion 113 (corresponding to the distance d3) is reduced. Due to this change in the distance, similar to the first embodiment, the relative positional relationship between the positions of the first wall portion 112 and the second wall portion 113 and the position of the second adhesive member 12 can be fixed, and the attachment and detachment of the first member 301 to and from the first adhesive member 11 are facilitated.

[0056] In the second embodiment, similar to the first embodiment, when attaching and detaching the constituent members of the bush 31 to and from each adhesive member, a gap is provided between the first wall portion 112 and the second wall portion 113 and the first member 301 to ensure workability. When crimping the first member 301 and the second member 302 to the main body portion 2, the first member 301 is sandwiched by the first wall portion 112 and the second wall portion 113 to fix the position. Therefore, crimping can be performed while suppressing displacement of the crimping surface with respect to the main body portions 2 of the first member 301 and the second member 302. According to the second embodiment, it is possible to surely perform the crimping of the bush 31 to the main body portion 2 while suppressing a decrease in workability.

[0057] (Embodiment 3) Next, Embodiment 3 of the present invention will be described with reference to FIGS. 12 and 13. FIGS. 12 and 13 are plan views for explaining the configuration of an adhesive jig for adhering a bush to a main body portion in Embodiment 3. In the third embodiment, the configuration of the first adhesive member will be described.

[0058] The first adhesive member 11B according to Embodiment 3 includes a bottom surface portion 115 on which the first member 301 is placed, a first wall portion 116A and a second wall portion 116B placed on the bottom surface portion 115, and a first moving mechanism 117A and a second moving mechanism 117B for moving the first wall portion 116A and the second wall portion 116B. In the first adhesive member 11B, the first wall portion 116A and the second wall portion 116B are provided so as to be movable in a direction approaching or separating from each other. The first moving mechanism 117A and the second moving mechanism 117B correspond to a switching mechanism.

[0059] The first moving mechanism 117A has a fulcrum portion 117a fixed to the bottom surface portion 115, a force point portion 117b to which a load from the second adhesive member is applied, and an acting portion 117c for moving the first wall portion 116A in accordance with the load applied to the force point portion 117b. The fulcrum portion 117a and the force point portion 117b, and the force point portion 117b and the acting portion 117c are connected by connecting members, respectively.

[0060] In the first moving mechanism 117A, when a load in the direction of the arrow in FIG. 12 is applied to the force point portion 117b, the force point portion 117b moves toward the bottom surface portion 115 side. Due to the movement of the force point portion 117b, the acting portion 117c moves in a direction away from the fulcrum portion 117a. As a result, the first wall portion 116A moves toward the second wall portion 116B side.

[0061] The second moving mechanism 117B also has the same configuration as the first moving mechanism 117A. In the second moving mechanism 117B, when a load is applied to the force point portion 117b, the force point portion 117b moves toward the bottom surface portion 115 side. Due to the movement of the force point portion 117b, the acting portion 117c moves in a direction away from the fulcrum portion 117a. As a result, the second wall portion 116B moves toward the first wall portion 116A side. At this time, the first moving mechanism 117A is configured to maintain the shape in which the first wall portion 116A and the second wall portion 116B are separated from each other as shown in FIG. 12 in a state where no load other than gravity is applied. Further, the first wall portion 116A and the second wall portion 116B are biased in a direction away from each other by a biasing member (not shown).

[0062] The second bonding member only needs to be able to hold the second member 302 and contact the force point portion 117b to apply a load. For example, it can be applied by adjusting the positions of the first wall portion 122 and the second wall portion 123 of the second bonding member 12, and the positions of the first pin 125 and the second pin 126 of the second bonding member 12A.

[0063] Here, in a state where the first bonding member 11B is not receiving the load from the second bonding member, the distance between the inner walls of the first wall portion 116A and the second wall portion 116B (corresponding to the distance d3) is larger than the width of the first member 301 (the distance d4 shown in FIG. 7), and when the second bonding member is placed over the first bonding member 11B, the distance between the inner walls of the first wall portion 112 and the second wall portion 113 is set to be approximately the same as the width d4.

[0064] In the bonding jig, when the second bonding member is placed over the first bonding member 11B, the distance between the first wall portion 116A and the second wall portion 116B (corresponding to the distance d3) shrinks. Due to this change in distance, similar to Embodiment 1, the relative positional relationship between the positions of the first wall portion 116A and the second wall portion 116B and the position of the second bonding member can be fixed, and the attachment and detachment of the first member 301 to and from the first bonding member 11 become easy.

[0065] In Embodiment 3, similar to Embodiment 1, when attaching and detaching the constituent members of the bush 31 to each bonding member, a gap is provided between the first wall portion 116A and the second wall portion 116B and the first member 301 to ensure workability. When crimping the first member 301 and the second member 302 to the main body portion 2, the first member 301 is sandwiched by the first wall portion 116A and the second wall portion 116B to fix the position. Therefore, crimping can be performed while suppressing the displacement of the crimping surface with respect to the main body portions 2 of the first member 301 and the second member 302. According to Embodiment 3, it is possible to reliably perform the crimping of the bush 31 to the main body portion 2 while suppressing a decrease in workability.

[0066] (Embodiment 4) Next, Embodiment 4 of the present invention will be described with reference to FIGS. 14 and 15. FIGS. 14 and 15 are plan views for explaining the configuration of an adhesive jig for adhering a bush to a main body part in Embodiment 4.

[0067] The first adhesive member 11C according to Embodiment 4 includes a bottom surface portion 115 on which the first member 301 is placed, a first wall portion 116A and a second wall portion 116B placed on the bottom surface portion 115, and a first moving mechanism 117C and a second moving mechanism 117D for moving the first wall portion 116A and the second wall portion 116B. The first moving mechanism 117C and the second moving mechanism 117D correspond to a switching mechanism.

[0068] The first moving mechanism 117C has a fulcrum portion 117d fixed to the bottom surface portion 115, a force point portion 117e to which a load from the second adhesive member is applied, and an acting portion 117f for moving the first wall portion 116A in response to the load applied to the force point portion 117e. The fulcrum portion 117d and the acting portion 117c are connected by a connecting member 117g.

[0069] In the first moving mechanism 117C, when a load in the direction of the arrow in FIG. 14 is applied to the force point portion 117e, the force point portion 117e moves toward the bottom surface portion 115. The force point portion 117e abuts on the connecting member 117g by the movement and pushes down the connecting member 117g. The connecting member 117g rotates around the fulcrum portion 117d and moves the acting portion 117f. The acting portion 117f slides with respect to the first wall portion 116A. Thereby, the first wall portion 116A moves toward the second wall portion 116B.

[0070] The second moving mechanism 117D also has the same configuration as the first moving mechanism 117C. In the first moving mechanism 117C, when a load is applied to the force point portion 117e, the force point portion 117e moves toward the bottom surface portion 115. Due to the movement of the force point portion 117e, the acting portion 117f slides with respect to the second wall portion 116B. Thereby, the second wall portion 116B moves toward the first wall portion 116A.

[0071] The second bonding member may be any member that can hold the second member 302 and apply a load by contacting the force application point portion 117e. For example, it can be applied by adjusting the positions of the first wall portion 122 and the second wall portion 123 of the second bonding member 12, or the positions of the first pin 125 and the second pin 126 of the second bonding member 12A. Also, it may be configured such that the force application point portion 117e is provided at the end of the second bonding member.

[0072] Here, in a state where the first bonding member 11C is not receiving the load from the second bonding member, the distance between the inner walls of the first wall portion 116A and the second wall portion 116B (corresponding to the distance d3) is larger than the width of the first member 301 (the distance d4 shown in FIG. 7), and when the second bonding member is placed over the first bonding member 11B, the distance between the inner walls of the first wall portion 112 and the second wall portion 113 is set to be approximately the same as the width d4.

[0073] In the bonding jig, when the second bonding member is placed over the first bonding member 11C, the distance between the first wall portion 116A and the second wall portion 116B (corresponding to the distance d3) shrinks. Due to this change in distance, similar to Embodiment 1, the relative positional relationship between the positions of the first wall portion 116A and the second wall portion 116B and the position of the second bonding member can be fixed, and the attachment and detachment of the first member 301 to and from the first bonding member 11 become easy.

[0074] In the present Embodiment 4, similar to Embodiment 1, when attaching and detaching the constituent members of the bush 31 to each bonding member, a gap is provided between the first wall portion 116A and the second wall portion 116B and the first member 301 to ensure workability, and when crimping the first member 301 and the second member 302 to the main body portion 2, the first member 301 is sandwiched between the first wall portion 116A and the second wall portion 116B to fix the position, so that crimping can be performed while suppressing displacement of the crimping surface with respect to the main body portions 2 of the first member 301 and the second member 302. According to the present Embodiment 4, it is possible to surely perform the crimping of the bush 31 to the main body portion 2 while suppressing a decrease in workability.

[0075] (Embodiment 5) Next, Embodiment 5 of the present invention will be described with reference to FIG. 16. FIG. 16 is a plan view for explaining the configuration of an adhesive jig for adhering a bush to a main body portion in Embodiment 5. Note that the same reference numerals are given to the same parts as those of the adhesive jig 10 according to Embodiment 1.

[0076] The adhesive jig 10B according to Embodiment 5 includes a first adhesive member 11D, a second adhesive member 12B, and a wedge 13. By covering the first adhesive member 11D with the second adhesive member 12B, the wedge 13 enters the first adhesive member 11D and crimps the first member 301 and the second member 302 to the main body portion 2.

[0077] The first adhesive member 11D has a main body portion 115A in which a housing portion 115a for housing the first member 301 is formed. The housing portion 115a includes a bottom surface 115b on which the first member 301 is placed and a side surface 115c that extends obliquely in a direction in which the internal space expands with respect to the bottom surface 115b.

[0078] The second adhesive member 12B has a main body portion 124 that holds the second member 302.

[0079] The wedge 13 has a first claw portion 131 and a second claw portion 132 that extend in a conical shape. The first claw portion 131 and the second claw portion 132 are designed to be equal to the width of the first member 301 (distance d4 shown in FIG. 7) when they enter the first adhesive member 11D. The wedge 13 (the first claw portion 131 and the second claw portion 132) constitutes a switching mechanism.

[0080] Here, in a state where the first adhesive member 11D is not receiving the load from the second adhesive member 12B, the shortest distance between the opposing side surfaces 115c is the distance between the end portions on the side continuous with the bottom surface 115b, which is equivalent to that of the first member 301. Also, the shortest distance between the opposing side surfaces 115c is the distance between the end portions on the side continuous with the bottom surface 115b, which is equivalent to the first member 301 (width d4). Further, the longest distance between the opposing side surfaces 115c, which is the distance between the end portions (openings) on the side opposite to the bottom surface 115b side, is larger than the width of the first member 301 (the distance d4 shown in FIG. 7) (corresponding to the distance d3).

[0081] In the bonding jig 10B, when the second adhesive member 12B is placed over the first adhesive member 11D, the first claw portion 131 and the second claw portion 132 enter the accommodating portion 115a. By inserting the first claw portion 131 and the second claw portion 132 into the accommodating portion 115a, the distance between the wall surfaces within the accommodating portion 115a (corresponding to the distance d3) is reduced. Due to this change in distance, the relative positional relationship between the position of the first member 301 in the first adhesive member 11D and the position of the second member 302 in the second adhesive member 12 can be fixed, and the attachment and detachment of the first member 301 to and from the first adhesive member 11 become easy.

[0082] In the fifth embodiment, similar to the first embodiment, when attaching and detaching the constituent members of the bush 31 to each adhesive member, a gap is provided between the first member 301 in the accommodating portion 115a to ensure workability, and when crimping to the main body portions 2 of the first member 301 and the second member 302, the first member 301 is sandwiched by the first claw portion 131 and the second claw portion 132 to fix the position. Thus, crimping can be performed while suppressing the displacement of the crimping surface with respect to the main body portions 2 of the first member 301 and the second member 302. According to the fifth embodiment, it is possible to reliably perform the crimping of the bush 31 to the main body portion 2 while suppressing a decrease in workability.

[0083] (Embodiment 6) Next, Embodiment 6 of the present invention will be described with reference to FIG. 17. FIG. 17 is a plan view for explaining the configuration of an adhesive jig for adhering a bush to a main body portion in Embodiment 6. In Embodiment 6, the configuration of a first adhesive member will be described.

[0084] The first adhesive member 11E according to Embodiment 6 has a main body portion 118 in which a housing portion 118a for housing the first member 301 is formed. The main body portion 118 has a first plate 118b and a second plate 118c provided at the open end of the housing portion 118a and rotatable about the corners of the housing portion 118a as fulcrums. The first plate 118b and the second plate 118c may be connected so as not to separate from the main body portion 118, or may be separate from the main body portion 118. The first plate 118b and the second plate 118c constitute a switching mechanism.

[0085] In a state where no load other than gravity is applied, the first plate 118b and the second plate 118c can be inclined so that the outer side extends with respect to the housing portion 118a, whereby the first member 301 can be easily housed. On the other hand, after the adhesion process, by pulling out the first plate 118b and the second plate 118c, a gap is generated between the housing portion 118a and the first member 301 by the thickness of the plate, and the first member 301 can be easily withdrawn from the housing portion 118a.

[0086] The second adhesive member only needs to hold the second member 302 and not interfere with the first plate 118b and the second plate 118c when covering the first adhesive member 11E. For example, it can be applied by adjusting the positions of the first wall portion 122 and the second wall portion 123 of the second adhesive member 12.

[0087] Here, in a state where the first adhesive member 11E is not receiving the load from the second adhesive member, among the distances between the first plate 118b and the second plate 118c, the maximum distance d5 is larger than the width of the first member 301 (the distance d4 shown in FIG. 7). Further, when the first plate 118b and the second plate 118c are accommodated in the accommodating portion 118a, the distance d6 between the first plate 118b and the second plate 118c is set to be approximately the same as the width d4.

[0088] In the bonding jig, when the first plate 118b and the second plate 118c are accommodated in the accommodating portion 118a from an inclined state outside the accommodating portion 118a, the distance between the first plate 118b and the second plate 118c is reduced. Due to this change in distance, similar to Embodiment 1, the relative positional relationship between the position of the first member 301 by the first plate 118b and the second plate 118c and the position of the second member 302 of the second adhesive member can be fixed, and the attachment and detachment of the first member 301 to the first adhesive member 11 become easy.

[0089] In the sixth embodiment, similar to the first embodiment, when attaching and detaching the constituent members of the bush 31 to each adhesive member, a gap is provided between the accommodating portion 118a and the first member 301 to ensure workability, and when crimping the first member 301 and the second member 302 to the main body portion 2, the first member 301 is sandwiched by the first plate 118b and the second plate 118c to fix the position. Therefore, crimping can be performed while suppressing the deviation of the crimping surface with respect to the main body portions 2 of the first member 301 and the second member 302. According to the sixth embodiment, it is possible to surely perform the crimping of the bush 31 to the main body portion 2 while suppressing a decrease in workability.

[0090] (Embodiment 7) Next, a seventh embodiment of the present invention will be described with reference to FIGS. 18 and 19. FIGS. 18 and 19 are plan views for explaining the configuration of a bonding jig for bonding a bush to a main body portion in the seventh embodiment. In the seventh embodiment, the configuration of the first adhesive member will be described.

[0091] The first adhesive member 11F according to Embodiment 7 has a main body portion 119a, a first holding portion 119b formed by bending a plate-like member, and a second holding portion 119c. The first holding portion 119b rotates around a shaft 119d. The second holding portion 119c rotates around a shaft 119e. The shafts 119d and 119e are fixed to the main body portion 119a and attached to the bent portions of the respective holding portions. The first holding portion 119b and the second holding portion 119c accommodate the first member 301 between portions (hereinafter referred to as wall portions 119f and 119g) that rise from and extend from the main body portion 119a. The first holding portion 119b and the second holding portion 119c constitute a switching mechanism.

[0092] In a state where no load other than gravity is applied, the first holding portion 119b and the second holding portion 119c can easily accommodate and remove the first member 301 by inclining such that the wall portions 119f and 119g spread outward (see FIG. 18). On the other hand, when the first member 301 is placed, the first holding portion 119b and the second holding portion 119c rotate, and the wall portions 119f and 119g sandwich the first member 301 (see FIG. 19).

[0093] The second adhesive member may hold the second member 302 and may be such that it does not interfere with the first holding portion 119b and the second holding portion 119c when covering the first adhesive member 11F. For example, it can be applied by adjusting the positions of the first wall portion 122 and the second wall portion 123 of the second adhesive member 12.

[0094] Here, in a state where the first adhesive member 11F is not receiving a load from the second adhesive member, among the distances between the wall portions 119f and 119g, the maximum distance d7 is larger than the width of the first member 301 (the distance d4 shown in FIG. 7). Also, when the first member 301 is placed and the first holding portion 119b and the second holding portion 119c rotate, the distance d8 between the wall portions 119f and 119g is set to be approximately the same as the width d4.

[0095] Next, with the jig, when the wall portions 119f and 119g are placed on the first member 301 at the first holding portion 119b and the second holding portion 119c from the state where they are inclined in a direction away from each other, the distance between the wall portions 119f and 119g is reduced. Due to this change in distance, similar to the first embodiment, the relative positional relationship between the position of the first member 301 by the first holding portion 119b and the second holding portion 119c and the position of the second member 302 of the second adhesive member can be fixed, and it becomes easy to attach and detach the first member 301 to and from the first adhesive member 11.

[0096] In the seventh embodiment, similar to the first embodiment, when attaching and detaching the constituent members of the bush 31 to each adhesive member, a gap is provided between the first holding portion 119b and the second holding portion 119c (wall portions 119f and 119g) and the first member 301 to ensure workability. When crimping the first member 301 and the second member 302 to the main body portion 2, the wall portions 119f and 119g sandwich the first member 301 to fix the position, so that crimping can be performed while suppressing the displacement of the crimping surface with respect to the main body portion 2 of the first member 301 and the second member 302. According to the seventh embodiment, it is possible to surely perform the crimping of the bush 31 to the main body portion 2 while suppressing a decrease in workability.

[0097] (Eighth Embodiment) Next, the eighth embodiment of the present invention will be described with reference to FIGS. 20 and 21. FIG. 20 is a plan view for explaining the configuration of an adhesive jig for adhering a bush to a main body portion in the eighth embodiment. FIG. 21 is a plan view showing the configuration of the adhesive jig as viewed from the direction of arrow A shown in FIG. 20. In the eighth embodiment, the configuration of the first adhesive member will be described.

[0098] The first adhesive member 11G according to the eighth embodiment includes a bottom surface portion 111A on which the first member 301 is placed, a first wall portion 112A and a second wall portion 113A that are respectively erected with respect to the bottom surface portion 111A on both end sides of the bottom surface portion 111A, and leaf springs 114A that bias the wall portions in a direction away from the bottom surface portion 111A.

[0099] The leaf spring 114A is included in a switching mechanism that switches between a first state in which a gap is formed between a part of the side surface of the first member 301 that is continuous with the crimping surface of the first member 301 and the second member 302 and the first adhesive member 11G in the space where the first adhesive member 11G holds the first member 301, and a second state in which the gap is filled to regulate the position of the first member 301. In Embodiment 8, the gap between the first member 301 and the first adhesive member 11G changes due to the movement of the first wall portion 112A and the second wall portion 113A.

[0100] The central portion of the leaf spring 114A is connected to the bottom surface portion 111A, and both end portions are connected to the first wall portion 112A (or the second wall portion 113A). The leaf spring 114A biases the connecting wall portion in a direction away from the bottom surface portion 111A. The leaf spring 114A is fixed to the bottom surface portion 111A and the wall portion by screwing, welding, or the like.

[0101] The second adhesive member may hold the second member 302 and, when covering the first adhesive member 11G, contact the first wall portion 112A and the second wall portion 113A to move the first wall portion 112A and the second wall portion 113A toward the bottom surface portion 111A side. For example, it can be applied by adjusting the positions of the first wall portion 122 and the second wall portion 123 of the second adhesive member 12.

[0102] Here, in a state where the first adhesive member 11G is not receiving the load from the second adhesive member, the distance between the first wall portion 112A and the second wall portion 113A is larger than the width of the first member 301 (width d4 shown in FIG. 7). Also, when the second adhesive member is attached to the first adhesive member, the distance between the first wall portion 112A and the second wall portion 113A is set to be approximately the same as the width d4.

[0103] In the eighth embodiment, as in the first embodiment, when attaching and detaching the constituent members of the bush 31 to each adhesive member, a gap is provided between the first wall portion 112A and the second wall portion 113A and the first member 301 to ensure workability. When the first member 301 and the second member 302 are crimped to the main body portion 2, the first wall portion 112A and the second wall portion 113A sandwich the first member 301 to fix its position. Therefore, crimping can be performed while suppressing displacement of the crimping surface with respect to the main body portions 2 of the first member 301 and the second member 302. According to the eighth embodiment, it is possible to surely perform the crimping of the bush 31 to the main body portion 2 while suppressing a decrease in workability.

[0104] (Ninth Embodiment) Next, a ninth embodiment of the present invention will be described with reference to FIG. 22. FIG. 22 is a plan view for explaining the configuration of an adhesive jig for adhering a bush to a main body portion in the ninth embodiment. In the ninth embodiment, the configuration of the first adhesive member will be described.

[0105] The first adhesive member 11H according to the ninth embodiment includes a bottom surface portion 111A on which the first member 301 is placed, a first wall portion 112B and a second wall portion 113B that are respectively erected with respect to the bottom surface portion 111A on both end sides of the bottom surface portion 111A, and a first inclined portion 141 and a second inclined portion 142 that movably hold the wall portions.

[0106] The first inclined portion 141 and the second inclined portion 142 are inclined and extend downward as they move away from the bottom surface portion 111A. For this reason, the first wall portion 112B and the second wall portion 113B move in a direction away from the bottom surface portion 111A by their own weight in a state where no load other than gravity is applied. The first inclined portion 141 and the second inclined portion 142 are included in a switching mechanism that switches between a first state in which a gap is formed between a part of the side surface of the first member 301 that is continuous with the crimping surface with the second member 302 and the first adhesive member 11H in the space where the first adhesive member 11H holds the first member 301, and a second state in which this gap is filled to regulate the position of the first member 301.

[0107] The second adhesive member only needs to hold the second member 302 and, when covering the first adhesive member 11H, contact the first wall portion 112B and the second wall portion 113B to move the first wall portion 112B and the second wall portion 113B toward the bottom surface portion 111A. For example, it can be applied by adjusting the positions of the first wall portion 122 and the second wall portion 123 of the second adhesive member 12.

[0108] At this time, due to the attachment of the second adhesive member, the first wall portion 112B and the second wall portion 113B respectively rise along the first inclined portion 141 and the second inclined portion 142 and approach the bottom surface portion 111A. Also, when the second adhesive member is removed, the first wall portion 112B and the second wall portion 113B respectively descend along the first inclined portion 141 and the second inclined portion 142 by their own weights and move away from the bottom surface portion 111A.

[0109] Here, in a state where the first adhesive member 11H is not receiving the load from the second adhesive member, the distances between the first wall portion 112B and the second wall portion 113B are larger than the width of the first member 301 (width d4 shown in FIG. 7). Also, when the second adhesive member is attached to the first adhesive member, the distances between the first wall portion 112B and the second wall portion 113B are set to be approximately the same as the width d4.

[0110] In the ninth embodiment, similar to the first embodiment, when attaching and detaching the constituent members of the bush 31 to each adhesive member, a gap is provided between the first wall portion 112B and the second wall portion 113B and the first member 301 to ensure workability. Also, when crimping to the main body portions 2 of the first member 301 and the second member 302, since the first wall portion 112B and the second wall portion 113B sandwich the first member 301 to fix the position, it is possible to perform crimping that suppresses displacement of the crimping surface with respect to the main body portions 2 of the first member 301 and the second member 302. According to the ninth embodiment, it is possible to surely perform the crimping of the bush 31 to the main body portion 2 while suppressing a decrease in workability.

[0111] (Tenth Embodiment) Next, Embodiment 10 of the present invention will be described with reference to FIG. 23. FIG. 23 is a plan view for explaining the configuration of an adhesive jig for adhering a bush to a main body portion in Embodiment 10. In the present Embodiment 10, the configuration of the first adhesive member will be described.

[0112] The first adhesive member 11I according to Embodiment 10 includes a bottom surface portion 111B on which the first member 301 is placed, a first wall portion 112C and a second wall portion 113C that are erected so as to be movable with respect to the bottom surface portion 111B, and a first magnetic portion 143 and a second magnetic portion 144 that generate a force for moving the wall portions.

[0113] The first wall portion 112C and the second wall portion 113C are formed of a magnetic material.

[0114] The first magnetic portion 143 and the second magnetic portion 144 are configured using, for example, electromagnets, and the energization is controlled by a control device (not shown). For this reason, the first wall portion 112C and the second wall portion 113C move in a direction away from the bottom surface portion 111A according to the energization state of the first magnetic portion 143 and the second magnetic portion 144. For example, when the first magnetic portion 143 and the second magnetic portion 144 are energized, the first wall portion 112C and the second wall portion 113C move in a direction away from each other by the magnetic force generated by the first magnetic portion 143 and the second magnetic portion 144. The first magnetic portion 143 and the second magnetic portion 144 are included in a switching mechanism that switches between a first state in which a gap is formed between a part of the side surface continuous with the pressure-bonding surface of the first member 301 and the first adhesive member 11I in the space where the first adhesive member 11I holds the first member 301, and a second state in which this gap is filled to regulate the position of the first member 301.

[0115] The second adhesive member may be any member that holds the second member 302 and, when covered on the first adhesive member 11I, contacts the first wall portion 112C and the second wall portion 113C and moves the first wall portion 112C and the second wall portion 113C toward the bottom surface portion 111B side. For example, it can be applied by adjusting the positions of the first wall portion 122 and the second wall portion 123 of the second adhesive member 12. In addition, if the positions of the first wall portion 112C and the second wall portion 113C can be controlled by attaching the second adhesive member, the first magnetic portion 143 and the second magnetic portion 144 may be energized constantly, or may be energized at necessary timings. Further, if the movement of the first wall portion 112C and the second wall portion 113C can be controlled by magnetic force, the second adhesive member may not have the first wall portion 122 and the second wall portion 123.

[0116] Here, in a state where the first adhesive member 11I is not receiving the load from the second adhesive member, the distance between the first wall portion 112C and the second wall portion 113C is larger than the width of the first member 301 (width d4 shown in FIG. 7). Further, when the second adhesive member is attached to the first adhesive member, the distance between the first wall portion 112C and the second wall portion 113C is set to be approximately the same as the width d4.

[0117] In the tenth embodiment, similar to the first embodiment, when attaching and detaching the constituent members of the bush 31 to each adhesive member, a gap is provided between the first wall portion 112C and the second wall portion 113C and the first member 301 to ensure workability. When crimping to the main body portions 2 of the first member 301 and the second member 302, the first wall portion 112C and the second wall portion 113C sandwich the first member 301 to fix the position. Therefore, crimping can be performed while suppressing the displacement of the crimping surface with respect to the main body portions 2 of the first member 301 and the second member 302. According to the ninth embodiment, it is possible to surely perform the crimping of the bush 31 with respect to the main body portion 2 while suppressing the deterioration of workability.

[0118] (Embodiment 11) Next, the eleventh embodiment of the present invention will be described with reference to FIG. 24. FIG. 24 is a plan view for explaining the configuration of an adhesive jig for adhering a bush to a main body portion in the eleventh embodiment. In the eleventh embodiment, the configuration of the first adhesive member will be described.

[0119] The first adhesive member 11J according to Embodiment 11 has a bottom surface portion 111 on which the first member 301 is placed, a first wall portion 112D and a second wall portion 113D that are respectively erected on both end sides of the bottom surface portion 111 with respect to the bottom surface portion 111, and a first screw portion 145 and a second screw portion 146 that movably hold the wall portions respectively.

[0120] The first screw portion 145 is in the shape of a rod extending from the bottom surface portion 111 and penetrates the first wall portion 112D. Threads are formed on the first screw portion 145 and are screwed with the first wall portion 112D. By rotating around the longitudinal axis of the first screw portion 145, the first wall portion 112D moves in the longitudinal axis direction. Also, the moving direction of the first wall portion 112D is determined according to the rotation direction of the first screw portion 145. The rotation of the first screw portion 145 may be manually rotated by the user or electrically rotated by a motor or the like. Note that the second screw portion 146 extends from the bottom surface portion 111 in a direction opposite to the first screw portion 145 and penetrates the first wall portion 112D. The second screw portion 146 is formed with threads in the same manner as the first screw portion 145 and moves the second wall portion 113D by rotation.

[0121] The first screw portion 145 and the second screw portion 146 are included in a switching mechanism that switches between a first state in which a gap is formed between a part of the side surface continuous with the crimping surface of the first member 301 and the second member 302 and the first adhesive member 11J in the space where the first adhesive member 11J holds the first member 301, and a second state in which the gap is filled to regulate the position of the first member 301.

[0122] The second adhesive member may be any member that holds the second member 302 and can bring the second member 302 into contact with the first member 301 held by the first adhesive member 11J when the second adhesive member is placed on the first adhesive member 11J.

[0123] In Embodiment 11, when attaching the second adhesive member, the first screw portion 145 and the second screw portion 146 are rotated to move the first wall portion 112D and the second wall portion 113D toward the bottom surface portion 111. Also, after the adhesion process, the first screw portion 145 and the second screw portion 146 are rotated to move the first wall portion 112D and the second wall portion 113D away from the bottom surface portion 111.

[0124] Here, when attaching or detaching the first member 301, the distance between the first wall portion 112D and the second wall portion 113D is larger than the width of the first member 301 (width d4 shown in FIG. 7). Also, when adhering the first member 301 and the second member 302, the distance between the first wall portion 112D and the second wall portion 113D is set to be approximately the same as the width d4.

[0125] In this Embodiment 11, similar to Embodiment 1, when attaching and detaching the constituent members of the bush 31 to each adhesive member, a gap is provided between the first wall portion 112D and the second wall portion 113D and the first member 301 to ensure workability. Also, when crimping to the main body portion 2 of the first member 301 and the second member 302, since the first wall portion 112D and the second wall portion 113D sandwich the first member 301 to fix the position, crimping can be performed while suppressing displacement of the crimping surface with respect to the main body portion 2 of the first member 301 and the second member 302. According to this Embodiment 11, it is possible to surely perform the crimping of the bush 31 to the main body portion 2 while suppressing a decrease in workability.

[0126] (Embodiment 12) Next, Embodiment 12 of the present invention will be described with reference to FIG. 25. FIG. 25 is a plan view for explaining the configuration of an adhesion jig for adhering a bush to a main body portion in Embodiment 12. In this Embodiment 11, the configuration of the first adhesive member will be described.

[0127] The first adhesive member 11K according to Embodiment 12 includes a bottom surface portion 111C on which the first member 301 is placed, a first wall portion 112D and a second wall portion 113D that are respectively erected on both end side portions of the bottom surface portion 111C with respect to the bottom surface portion 111C, and a link mechanism 15 that movably holds the wall portions respectively.

[0128] The link mechanism 15 includes an operation portion 151 provided on the bottom surface portion 111C, a first support portion 152 attached to the first wall portion 112A, a second support portion 153 attached to the second wall portion 113A, a first link 154 connecting the operation portion 151 and the first support portion 152, and a second link 155 connecting the operation portion 151 and the second support portion 153. In the link mechanism 15, when the operation portion 151 is pushed into the bottom surface portion 111C, the first support portion 152 and the second support portion 153 move in a direction away from each other via the first link 154 and the second link 155. Thereby, the wall portions supported by the respective support portions also move.

[0129] The link mechanism 15 constitutes a switching mechanism that switches between a first state in which a gap is formed between a part of a side surface continuous with the crimping surface of the first member 301 and the second member 302 and the first adhesive member 11K in the space where the first adhesive member 11K holds the first member 301, and a second state in which this gap is filled to regulate the position of the first member 301.

[0130] The second adhesive member may be any member that holds the second member 302 and can bring the second member 302 into contact with the first member 301 held by the first adhesive member 11K when the second adhesive member is placed over the first adhesive member 11K.

[0131] In Embodiment 12, when attaching the second adhesive member, the operation portion 151 is pushed in to move the first wall portion 112A and the second wall portion 113A in a direction approaching each other. Further, after the adhesion process, the pressing of the operation portion 151 is released to move the first wall portion 112A and the second wall portion 113A in a direction away from each other.

[0132] Here, when the operation unit 151 is pushed in, the distance between the first wall portion 112A and the second wall portion 113A is larger than the width of the first member 301 (width d4 shown in FIG. 7). Also, when no load other than gravity is applied to the operation unit 151, the distance between the first wall portion 112A and the second wall portion 113A is set to be approximately the same as the width d4.

[0133] In the twelfth embodiment, similar to the first embodiment, when attaching and detaching the constituent members of the bush 31 to each adhesive member, a gap is provided between the first wall portion 112A and the second wall portion 113A and the first member 301 to ensure workability. When crimping to the main body portions 2 of the first member 301 and the second member 302, the first member 301 is sandwiched by the first wall portion 112A and the second wall portion 113A to fix the position. Therefore, crimping can be performed while suppressing the displacement of the crimping surface with respect to the main body portions 2 of the first member 301 and the second member 302. According to the twelfth embodiment, it is possible to surely perform the crimping of the bush 31 to the main body portion 2 while suppressing a decrease in workability.

[0134] (Embodiment 13) Next, the thirteenth embodiment of the present invention will be described with reference to FIG. 26. FIG. 26 is a plan view for explaining the configuration of an adhesive jig for adhering a bush to a main body portion in the thirteenth embodiment. In the thirteenth embodiment, the configuration of the first adhesive member will be described.

[0135] The first adhesive member 11L according to the thirteenth embodiment has a bottom surface portion 111D on which the first member 301 is placed, and a first wall portion 112E and a second wall portion 113E that are respectively erected with respect to the bottom surface portion 111D on both end sides of the bottom surface portion 111D.

[0136] On the first wall portion 112E and the second wall portion 113E, switching surfaces 112b and 113b are formed which are switching surfaces forming wall surfaces facing the bottom surface portion 111D and form acute angles with the wall surfaces facing the first member 301. For this reason, in a natural state where no load other than gravity is applied, the first wall portion 112E and the second wall portion 113E incline in a mode where the switching surfaces and the bottom surface portion 111D are in surface contact due to their own weights. As a result, in the natural state, the wall surfaces of the first wall portion 112E and the second wall portion 113E facing the first member 301 are in an inclined state, and a gap is formed between them and the first member 301. The first wall portion 112E and the second wall portion 113E, particularly the switching surfaces 112b and 113b, are included in a switching mechanism that switches between a first state where a gap is formed between a part of the side surfaces continuous with the pressure-bonding surface of the first member 301 and the second member 302 of the first member 301 and the first adhesive member 11L in the space where the first adhesive member 11L holds the first member 301, and a second state where this gap is filled to regulate the position of the first member 301.

[0137] The second adhesive member may be any member that holds the second member 302 and, when covering the first adhesive member 11L, contacts the first wall portion 112E and the second wall portion 113E and moves the first wall portion 112E and the second wall portion 113E toward the bottom surface portion 111A side. For example, it can be applied by adjusting the positions of the first wall portion 122 and the second wall portion 123 of the second adhesive member 12.

[0138] At this time, due to the attachment of the second adhesive member, the first wall portion 112B and the second wall portion 113B rotate, the switching surfaces 112b and 113b separate from the bottom surface portion 111D, and the first wall portion 112B and the second wall portion 113B approach each other. Also, when the second adhesive member is removed, the first wall portion 112B and the second wall portion 113B rotate, the switching surfaces 112b and 113b contact the bottom surface portion 111D, and the first wall portion 112B and the second wall portion 113B move away from each other.

[0139] Here, in a state where the first adhesive member 11L is not receiving the load from the second adhesive member, the maximum distance between the first wall portion 112E and the second wall portion 113E is larger than the width of the first member 301 (width d4 shown in FIG. 7). Also, when the second adhesive member is attached to the first adhesive member 11L, the distance between the first wall portion 112E and the second wall portion 113E is set to be approximately the same as the width d4.

[0140] In the thirteenth embodiment, similar to the first embodiment, when attaching and detaching the constituent members of the bush 31 to each adhesive member, a gap is provided between the first wall portion 112E and the second wall portion 113E and the first member 301 to ensure workability. Also, when crimping to the main body portions 2 of the first member 301 and the second member 302, the first wall portion 112E and the second wall portion 113E sandwich the first member 301 to fix the position. Therefore, it is possible to perform crimping that suppresses displacement of the crimping surface with respect to the main body portions 2 of the first member 301 and the second member 302. According to the thirteenth embodiment, it is possible to suppress a decrease in workability while surely performing the crimping of the bush 31 to the main body portion 2.

[0141] (Embodiment 14) Next, a fourteenth embodiment of the present invention will be described with reference to FIG. 27. FIG. 27 is a plan view for explaining the configuration of an adhesive jig for adhering a bush to a main body portion in the fourteenth embodiment. In the fourteenth embodiment, the configuration of the first adhesive member will be described.

[0142] The first adhesive member 11M according to the fourteenth embodiment has a bottom surface portion 111E on which the first member 301 is placed, and a first wall portion 112A and a second wall portion 113A that are respectively erected with respect to the bottom surface portion 111E on both end side portions of the bottom surface portion 111E.

[0143] The bottom surface portion 111E has a tubular shape with one end bifurcated, and an air flow path is formed inside, and the first member 301 is placed thereon. The bottom surface portion 111E has a first opening 111a, a second opening 111b that communicates with the first opening 111a, is provided at one bifurcated end, and faces the first wall portion 112A, and a third opening 111c that is provided at the other bifurcated end and faces the second wall portion 113A. The air introduced into the first opening 111a or sucked from the first opening 111a adjusts the air sucked or blown out from the second opening 111b and the third opening 111c. If air blows out from the second opening 111b and the third opening 111c, the first wall portion 112A and the second wall portion 113A move in a direction away from each other, and if air is sucked from the second opening 111b and the third opening 111c, the first wall portion 112A and the second wall portion 113A move in a direction approaching each other.

[0144] The bottom surface portion 111E is included in a switching mechanism that switches between a first state in which a gap is formed between a part of the side surface continuous with the crimping surface of the first member 301 and the second member 302 and the first adhesive member 11M in the space where the first adhesive member 11M holds the first member 301, and a second state in which this gap is filled to regulate the position of the first member 301.

[0145] The second adhesive member may be any one that holds the second member 302 and can bring the second member 302 into contact with the first member 301 held by the first adhesive member 11M when covered with the first adhesive member 11M.

[0146] In Embodiment 14, when attaching the second adhesive member, air is sucked from the first opening 111a to bring the first wall portion 112A and the second wall portion 113A closer to each other. Further, after the adhesion process, air is introduced into the first opening 111a to blow air onto the first wall portion 112A and the second wall portion 113A, and the first wall portion 112A and the second wall portion 113A are moved in a direction away from each other.

[0147] Here, when attaching or detaching the first member 301, the distance between the first wall portion 112A and the second wall portion 113A is larger than the width of the first member 301 (width d4 shown in FIG. 7). Also, when bonding the first member 301 and the second member 302, the distance between the first wall portion 112A and the second wall portion 113A is set to be approximately the same as the width d4.

[0148] In the fourteenth embodiment, similar to the first embodiment, when attaching and detaching the constituent members of the bush 31 to each adhesive member, a gap is provided between the first wall portion 112A and the second wall portion 113A and the first member 301 to ensure workability. Also, when crimping the first member 301 and the second member 302 to the main body portion 2, the first member 301 is sandwiched by the first wall portion 112A and the second wall portion 113A to fix the position, so that crimping can be performed while suppressing displacement of the crimping surface with respect to the main body portion 2 of the first member 301 and the second member 302. According to the fourteenth embodiment, it is possible to surely perform the crimping of the bush 31 to the main body portion 2 while suppressing a decrease in workability.

[0149] (Embodiment 15) Next, a fifteenth embodiment of the present invention will be described with reference to FIG. 28. FIG. 28 is a perspective view for explaining the configuration of a bush member in the fifteenth embodiment. In the fifteenth embodiment, the configuration of the bush member will be described.

[0150] The bush member 3A has a bush 31 and a bracket 32.

[0151] Similar to the first embodiment, the bush 31 is formed using an elastic material such as rubber or resin having elasticity, and functions as a damping member for damping vibrations of the stabilizer 1 transmitted from a road surface or the like. The bush 31 is composed of two members (the first member 301 and the second member 302). In the fifteenth embodiment, the first member 301 and the second member 302 constituting the bush 31 are divided in a direction parallel to the longitudinal direction of the main body portion 2 and orthogonal to the first embodiment.

[0152] Even the bush 31 divided in the aspect according to the fifteenth embodiment can bond members to each other using the same bonding jig as in the first to fourteenth embodiments, so that the same effects as in the first embodiment can be obtained.

[0153] So far, the embodiments for carrying out the present invention have been described, but the present invention should not be limited only by the above-described embodiments. For example, it is applicable to products manufactured by heat-pressure bonding treatment.

[0154] In the above-described embodiments, an example in which an IH coil is used as a heating member for heat treatment has been described. However, the heating member is not limited to these, and known ones (for example, heating by energization or heating by hot air) can be used and can be appropriately selected according to the heating efficiency and the like.

[0155] In the above-described embodiments, an example in which a bush connected to the vehicle body is bonded to the stabilizer has been described. However, not limited to the stabilizer, it is an adherend member to which a damping member that intervenes between connection targets and dampens vibrations between connection targets is bonded, and is applicable as long as it is an adherend member to which the damping member is bonded not limited to heating / non-heating. Examples of the adherend member include a stabilizer, a coil spring, a leaf spring, a torsion bar, a disc spring, and the like. For example, an insulator is used as a damping member for a coil spring.

[0156] Thus, the present invention can include various embodiments and the like not described herein, and various design changes and the like can be made without departing from the technical idea specified by the claims.

[0157] As described above, the bonding jig and the bonding method according to the present invention are suitable for surely performing pressure bonding of the damping member to the adherend member while suppressing a decrease in workability.
