[0050] The following is for reference Figures 1 to 6 The connecting member 8 of this embodiment will be described in detail below. The connecting member 8 is used to connect the first component 1 and the second component 2. In this embodiment, the first component 1 is an aluminum slide rail of the vehicle sunroof device, and the second component 2 is an iron crossbeam serving as the intermediate sheet metal of the vehicle sunroof device. However, the first component 1 and the second component 2 are not limited to the specific uses and materials described above, and can be any components. The first component 1 has a first hole 10, and the second component 2 has a second hole 20.
[0051] The connector 8 is a resin part formed as one piece, and the connector 8 is formed as one piece having a main body part 80, a connecting part 81, a movable part 82, an insertion part 83, a snap-fit part 84, a pin 85 and a locking part 88.
[0052] An insertion portion 83 protrudes from the main body portion 80, and a latching portion 84 protrudes from the main body portion 80 in one direction. An engaging portion 88 protrudes from the main body portion 80 in the opposite direction, which is the direction of movement of the connector 8 relative to the second hole 20 when fastened. The latching portion 84 has claws 86, the number of which is not limited, for example, two, three, or four. A pin hole 87 is formed on the inner side of the claws 86, and the pin hole 87 opens on the surface of the main body portion 80.
[0053] A pin 85 is provided protruding from the movable part 82, and a locking part 89 is provided in the movable part 82. In this embodiment, the locking part 89 is a hole that passes through the movable part 82.
[0054] In the pin 85, a rib 7 extending from the movable portion 82 toward the tip end of the pin 85 is provided, and the rib 7 is used to reinforce the pin 85 to prevent the pin 85 from breaking. The shape and number of the ribs 7 are not particularly limited, and for example, the ribs 7 can be shaped as shown in FIG. 8, which are tapered from the movable portion 82 toward the tip end of the pin 85. The second hole 20 of the second member 2 is not circular but is a special-shaped hole having a notch through which the rib 7 is inserted. Figure 2
[0055] The movable portion 82 is connected to the main portion 80 via the connecting portion 81, and the movable portion 82 is displaceable with respect to the main portion 80 via the connecting portion 81. In the present embodiment, the connecting portion 81 is a thin-walled portion that is bendable. As the bendable connecting portion 81, for example, a structure in which a plurality of piece portions are connected to each other by thin-walled portions and are bendable can be used. The connecting portion 81 can also be a thin-walled portion that is flexible and is elastically bendable and restorable. By bending the connecting portion 81, the movable portion 82 is movable to a position at which the pin 85 protruding from the movable portion 82 is insertable into the pin hole 87.
[0056] Next, the process of connecting the first member 1 and the second member 2 using the connecting member 8 will be described.
[0057] In the state in which the insertion portion 83 is inserted into the first hole 10 and the pawl 86 is latched in the second hole 20, the pin 85 is inserted into the pin hole 87, and thus the first member 1 is connected with respect to the second member 2.
[0058] Specifically, at the time of assembly, in the case where the pawl 86 of the clasp portion 84 is aligned with the second hole 20 of the second member 2, the connecting member 8 is pressed downward with the hand from above, and the pawl 86 of the clasp portion 84 is pressed into the second hole 20 of the second member 2. Thus, the pawl 86 is hooked to the lower surface 21 of the second hole 20. Since the clasp portion 84 has the bent-back shape of the pawl 86, the pawl 86 does not fall from the second hole 20 due to a weak external force. At the same time, at the time of disassembly, the latching of the clasp portion 84 to the second hole 20 can be easily released by simply causing the pawl 86 to retreat into the second hole 20, and the connecting member 8 can be easily reused.
[0059] In addition, the insertion portion 83 is not fastened to the first hole 10, and the insertion structure of the insertion portion 83 into the first hole 10 is only a structure that does not cause the insertion portion 83 to come off from the first hole 10 due to the bumping of the vehicle.
[0060] After that, the connecting portion 81 is bent so that the movable portion 82 is moved to a position where the pin 85 is inserted into the pin hole 87 together with the rib 7, and when the pin 85 is inserted into the pin hole 87, the engaging portion 88 is engaged with the engaged portion 89, that is, the engaging portion 88 in the form of a clamping jaw is clamped to the surface of the movable portion 82 through the engaged portion 89 which is a hole passing through the movable portion 82. The engaging structure of the engaging portion 88 and the engaged portion 89 is not particularly limited as long as the engaging portion 88 is engaged with the engaged portion 89 after the pin 85 is inserted into the pin hole 87.
[0061] Referring to Figure 5 When the clamping jaw 86 is clamped to the second hole 20, the pin 85 is inserted into the pin hole 87, and the engaging portion 88 is engaged with the engaged portion 89, the top end 85a of the pin 85 inserted into the pin hole 87 reaches the lower surface 21 of the second hole 20, thereby effectively preventing the clamping of the clamping jaw 86 and the second hole 20 from being released.
[0062] In the present embodiment, since the pin 85 which is the connecting portion 81 of the connecting member 8 as a thin-walled portion is integrally provided by bending the connecting member 8 itself and is inserted into the pin hole 87 formed by the clamping portion 84 which is inserted into the second hole 20 in advance, the connecting member 8 and the second member 2 can be fastened and linked using the connecting member 8 itself, and the connecting member 8 and the second member 2 can be fastened and linked in a simple manual manner without the need for additional components or tools. Furthermore, the structure in which the connecting member 8 and the second member 2 are fastened and linked and the first member 1 and the second member 2 are connected via the connecting member 8 can be formed by simultaneously inserting the insertion portion 83 into the first hole 10.
[0063] Furthermore, since the connecting member 8 as a whole is a soft resin material, it can be bent and bent without being broken and being separated. In addition, since it is further fixed by the engaging portion 88 after the pin 85 is inserted, it can prevent the pin 85 from falling out of the pin hole 87 due to external force (vibration input during transportation, etc.).
[0064] The above describes the preferred embodiment of the present application, but the present application is not limited thereto, and various modifications can be made without departing from the spirit of the present application.
[0065] For example, in the above embodiment, the engaged portion 89 is a hole passing through the movable portion 82, but the present application is not limited thereto, and the engaged portion 89 may, for example, be an edge portion of the movable portion 82, and the same technical effect can be achieved by engaging the engaging portion 88 with the edge portion of the movable portion 82.
[0066] For example, in the above embodiment, the connecting portion 81 is a thin-walled portion that is bendable, but the present application is not limited thereto, and the connecting portion 81 can also be a soft resin that is bendable. For example, the connecting portion 81 is a soft resin strip or a resin sheet that has a certain degree of flexibility in a natural state. Thus, the movable portion 82 can also be easily moved to a position at which the claw 86 of the clamping portion 84 and the second hole 20 are clamped.
[0067] For example, in the above embodiment, the connecting member 8 is a resin member that is formed in one piece, but the present application is not limited thereto, and the material of the connecting member 8 can be arbitrary as long as the same technical effects are achieved. For example, the connecting member can also be made of metal.
[0068] For example, in the above embodiment, the connecting member 8 integrally has the clamping portion 88, but the present application is not limited thereto, and for example, the clamping portion and the clamped portion can also not be provided.
[0069] The present application has been described above with reference to a specific example. However, the present application is not limited to this specific example. A design obtained by applying appropriate design changes to this specific example by a person skilled in the art is also included in the scope of the present application as long as the design has the features of the present application.
