Description

Technical area

[0001] The present invention relates to a body mounting structure, and more particularly to a body mounting structure that enables a mounting position, which varies due to dimensional tolerances, to be adjusted using a screw or a hook during assembly of a body to a part so that the part is positioned in the correct position. Explanation of the state of the art

[0002] When assembling a vehicle body with vehicle parts, the assembly positions vary slightly due to dimensional tolerances of the body and the parts. Therefore, especially in cases where assembly is carried out using modularization, appropriate tolerance management is required to position a module in the correct location.

[0003] For example, in a case where a plastic exterior door handle is assembled with a steel door frame, the door frame is subject to certain variations or deviations in each product during pressing, welding, assembly, and the like. Also, variations in the exterior door handle occur in each product due to shrinkage, deformation, dimensional incompatibilities, assembly tolerances, and the like.

[0004] Due to such variations, when the outside door handle is assembled with the door frame, problems arise in that the distance between the outside door handle and the door frame is different in each individual case, making it difficult to install the outside door handle in a correct position.

[0005] In addition, because uniformity of the vehicle's outer skin cannot be achieved with respect to the vehicle's exterior design, there is a problem that the aesthetic appearance is adversely affected.

[0006] Therefore, there is a need for a mounting structure that allows the distance between the door exterior handle and the door frame to be adjusted so that the deviations can be corrected.

[0007] An adjusting screw described in international patent application PCT / EP2017 / 076699 includes a spring element to compensate for tolerances. This adjusting screw presents a problem in that it is difficult for the spring element used for tolerance compensation to correct tolerances that occur in directions different from the longitudinal direction of the adjusting screw.

[0008] An adjusting element described in US Pat. No. 8,337,132 B2 comprises a hollow screw with an external thread and an internal thread, wherein a component holder is coupled to the external thread and an inner element is coupled to the internal thread, and a fastening device is adapted to the inside of the inner element and has a diameter that is smaller than the inner diameter of the inner element. Tolerances in the longitudinal direction of the hollow screw can be corrected using the hollow screw and the component holder, and tolerances in the radial direction of the hollow screw can be corrected by the fastening device. This adjusting element has a problem in that it has a complex structure and thus increases manufacturing costs.

[0009] US 2005 / 0 270 790 A1 describes a fastening device for fastening a headlight to a motor vehicle, which comprises a fastening device with

[0010] Means for holding a headlight housing and means for mounting the fastening device to a part of the vehicle. The means for fastening the fastening device are designed such that the fastening device is adjustable in at least one direction relative to the vehicle part before being fastened to the vehicle part.

[0011] US 2013 / 0 017 014 A1 describes a fastening arrangement for fastening a first component to a second component, which comprises a cylindrical element and a sleeve-shaped element, wherein the cylindrical element is fixed in the axial direction relative to the attached sleeve-shaped element.

[0012] US 2007 / 0 009 342 A1 describes a tolerance compensation unit for the automatic compensation of tolerances in the distance between two components to be clamped.

[0013] Korean utility model 20 1998 0 042 188 U describes a fastening arrangement. Summary of the technical problem

[0014] The present invention aims to provide a vehicle body mounting structure that enables a distance between a vehicle body and a part to be adjusted in each of the left-right and front-to-rear directions and the vertical direction with a simple structure such as a screw or a hook. Solution to the problem

[0015] A body mounting structure according to claim 1 is provided. The body mounting structure of the present invention includes a bolt non-rotatably fixed to a body or part, a fixing hole formed in the part so that the bolt can be inserted therein, a bushing inserted between the fixing hole and the bolt, a moving member configured to move the bushing in a forward and backward direction with respect to the fixing hole, and a nut fixed to the bolt, wherein the inner side surface of the bushing is spaced from the bolt and wherein the bushing is in contact with or fixed to the body of the vehicle when the bushing moves in said direction due to the fixing between the bolt and the nut.

[0016] The moving part has a female thread formed in the mounting hole and threads formed on the outer side surface of the bushing so as to be fastened to the female threaded part, wherein the pitch of the thread of the bushing may be larger than the pitch of the thread of the screw. A catch plate is formed on one surface of the part so as to protrude in the longitudinal direction of the mounting hole. A catch recess is formed between one surface of the part and the catch plate so as to be recessed in the direction of the inner diameter of the catch plate. A loosening preventing catch bracket is formed on the surface of the bushing so as to protrude in the direction of the outer diameter of the bushing. A catch projection inserted into the catch recess is formed on the catch bracket.The safety bracket is L-shaped and the safety projection at the rear end of each safety bracket is designed to protrude inwards.

[0017] The head of the screw may be welded to the body.

[0018] A screw retaining recess in the shape of a square prism may be formed in the part, the head of the screw may be formed in the shape of a square prism, and rotation of the head of the screw may be blocked by the screw retaining recess.

[0019] A catching projection that prevents loosening may be formed to protrude from a periphery of the bushing, and a fastening hook that is caught on the catching projection when the bushing rotates may be formed on the part.

[0020] A catching plate may be formed on a surface of the part so as to protrude in the longitudinal direction of the mounting hole; a catching recess may be formed between one surface of the part and the catching plate so as to be recessed in the direction of an inner diameter of the catching plate; a catching bracket for preventing loosening may be formed on a surface of the bushing so as to protrude from the bushing in the direction of the outer diameter, and a catching projection inserted into the catching recess may be formed on the catching bracket. Beneficial effects

[0021] A body mounting structure according to the present invention has the following advantageous effects: The distance between a body and a part can be adjusted with a simple structure using a screw shape that uses a female thread and a male thread part. The body mounting structure includes a bolt that is non-rotatably attached to the body or part, a mounting hole formed in the part to receive the bolt, a bushing inserted between the mounting hole and the bolt, a moving part configured to move the bushing in a forward or backward direction relative to the mounting hole, and a nut that is attached to the bolt. Thus, the bushing is in contact with and secured to the body when the bushing moves in the direction mentioned due to the attachment between the bolt and the nut. If the direction in which the bushing moves is the y-direction, the distance between the body and the part in the y-direction can be set or adjusted by the bushing.

[0022] An inner side surface of the bushing also has a distance from the screw. This allows the distance between the body and the part to be adjusted on the xz plane.

[0023] Because the bolt is welded to the body, it is possible to prevent rotation of the bolt caused by the rotation of the nut when the bolt and nut are fastened together.

[0024] A recess in the shape of a quadrangular prism is formed in the part, and the head of the screw is shaped in the shape of a quadrangular prism and inserted into the recess. This makes it possible to prevent rotation of the screw due to rotation of the nut when the screw and nut are fastened together.

These terms are intended to encompass other meanings or modes of action of a device in use, in addition to the meaning intended in the drawing; for example, if a device is inverted in the drawings with the top facing down, certain parts described as being "below" with respect to other parts should be understood as being "above" with respect to those parts. Thus, the word "below," being a descriptive term, can encompass both an upward and downward direction. The device can rotate through 90° or other angles, and the spatially relative terms should be interpreted accordingly.

[0030] In the exemplary embodiments of the present invention, the term "front-to-rear direction" refers to the left-right direction (width direction, y-direction) of a vehicle, the term "left-right direction" refers to the front-to-rear direction (longitudinal direction, x-direction) of the vehicle, and the term "vertical direction" refers to the vertical direction (z-direction) of the vehicle.

[0031] The following describes a structure for mounting a door handle to a vehicle body as an example of structures that can also be used to mount other vehicle parts. A vehicle body mounting structure according to the present invention can also be used when a vehicle part other than a door handle is mounted on the vehicle body and has a structure similar to a door handle. First embodiment

[0032] As in Fig. 1 and Fig. 2, a first exemplary embodiment of the present invention relates to a body mounting structure capable of adjusting the distance between a door frame 100 and an outside door handle during assembly.

[0033] The outside door handle includes a housing 400 mounted on the door frame 100, a handle part 300 installed in the housing 400 and capable of being pulled out to the outside of the vehicle or inserted into the housing 400 through the door frame 100, and a buffer member 200 mounted between the housing 400 and the door frame 100. Two housing mounting members 403 are formed on the left and right sides of the upper portion of the housing 400 to protrude upward. Also, one housing mounting member 403 is formed on the left side of the lower portion of the housing 400 to protrude downward. That is, three housing mounting members 403 are formed on the housing 400.

[0034] Door mounting elements 150, each arranged at a position corresponding to one of the housing mounting elements 403 and connected to the corresponding housing mounting element, are attached to the rear side of the door frame 100. The door mounting elements can be connected to the door frames by welding.

[0035] The housing mounting elements 403 and the door mounting elements 150 are each connected to each other by a distance adjustment unit 500, which will be described in more detail later.

[0036] As in Fig. 4, a door mounting member 150 comprises two mounting plates 151 connected to the door frames 100, and a mounting plate 152 formed to be recessed between the two mounting plates 151.

[0037] A screw mounting hole 153 is formed to be continuous from front to back in the center of the mounting plate 152.

[0038] As in Fig. 2, the door frame 100 includes a first handle through-hole 101 formed to extend continuously through the door frame 100 from front to rear, and an insert part 102 formed on the periphery of the first handle through-hole 101 to protrude rearward.

[0039] The first grip through-hole 101 is formed such that its inner circumferential line is spaced a predetermined distance from the outer circumferential line of the grip 300. Thus, the grip 300 can pass through the first grip through-hole 101.

[0040] As in Fig. 2 and Fig. 3, a buffer member 200 includes a second grip through-hole 201 formed to extend through the buffer member 200 from front to back, and a plurality of fixing rings 202 formed on the periphery of the buffer member 200.

[0041] The second grip through-hole 201 is formed such that its inner circumferential line is spaced a predetermined distance from the outer circumferential line of the grip 300. Thus, the grip 300 can pass through the first grip through-hole 101 and the second grip through-hole 201.

[0042] The fastening rings 202 are designed to be bent backward. A recess into which a fastening part 402 of the housing 400, described in more detail below, is fitted, is formed in each of the fastening rings 202.

[0043] The buffer member 200 is configured to protrude inward from the insert portion 102 and is installed to abut the periphery of the insert portion 102. The buffer member 200 prevents foreign matter from entering the housing 400 through the first grip portion through-hole 101 when the grip portion 300 is inserted.

[0044] As in Fig. 2, the housing 400 as a whole has the shape of a rectangular parallelepiped.

[0045] A plurality of outwardly projecting fastening protrusions 402 are formed on the periphery of the front surface of the housing 400. The buffer element 200 is connected to the front of the housing 400 by the fastening rings 202 and the fastening protrusions 402.

[0046] Guide projections 401 are formed to protrude from the front surface of the housing 400 at a total of six locations, namely on the left and right sides above the handle part 300, on the left and right sides below the handle part 300, and on the left and right of the handle part 300 at the base of the handle part 300.

[0047] As in Fig. 3, the guide projections 401 are arranged on the outer side of the insert part of the door frame 100. Also, the front surface of each guide part 401 is arranged in front of a rear surface of the insert part 102. That is, the guide projections 401 enclose the top, bottom, left, and right sides of the insert part 102. By means of the guide projections 401, the housing 400 can be positioned within a specific area around the insert part 102 of the door frame 100.

[0048] The housing mounting member 403 comprises a mounting hole formed continuously in the front-to-back direction and a mounting hook 404 formed in the lower portion of a receiving thread 403a, as shown in the Fig. 9 and Fig. Show 10.

[0049] The receiving thread 403a is formed in the mounting hole or bore. The threads of the receiving thread 403a can run at an angle of 30° or more.

[0050] The fastening hooks 404 protrude forward. The upper part of each fastening hook 404 is triangular. This means that a sloping section is formed on the left and right sides of the upper part of the fastening hooks 404.

[0051] The distance adjustment unit 500 includes a bushing 520 fixed to the female thread 403a of the housing mounting member 403, and a screw 510 connected to a nut 530 through the door mounting member 150 and the bushing 520.

[0052] The screw 510 includes a screw head 511 and a threaded portion 512 protruding from a surface of the screw head 511.

[0053] The screw 510 is inserted into the screw mounting hole 153 of the door mounting element 150 from the rear.

[0054] The outer diameter of the screw head 511 is larger than the inner diameter of the screw mounting hole 153, and the outer diameter of the threaded portion 512 is smaller than the inner diameter of the screw mounting hole 153. When the screw 150 is screwed into the screw mounting hole 153 from front to back, the screw head 511 is caught by the mounting plate 152 and prevented from falling out backward. Then, the screw 510 is welded and secured to the door mounting member 150.

[0055] Thus, when the screw 510 is fastened using the nut 530, the screw 510 and the nut 530 are prevented from rotating together.

[0056] The threaded portion 512 may be a standard thread and the threads of the threaded portion 512 may be at an angle of 5° or less.

[0057] The fixing plate 152 of the door mounting member 150 is configured such that the screw 510 is recessed rearwardly to an extent sufficient for the screw 510 to be inserted into the screw mounting hole 153 after being positioned in a clearance formed between the rear surface of the door frame 100 and the fixing plate 152.

[0058] The bushing 520 includes a first washer portion 521 and a male thread 522 formed on the back of the first washer portion 521 and secured to the female thread 403a of the housing mounting member 403.

[0059] The outer diameter of the first washer part 521 is larger than the inner diameter of the receiving thread 403a.

[0060] As in Fig. 9 and Fig. 10, two catch projections 521a are further formed on the first washer part 521. The catch projections 521a are formed on the first washer part 521 such that they are spaced apart from one another in the direction of its circumference.

[0061] The catching projections 521a are configured to protrude radially from the circumference of the first washer portion 521. Each catching projection 521a has a triangular shape. The catching projections 521a protrude sufficiently far to be caught on the fastening hook 404 when the bushing 520 rotates.

[0062] Since the catching protrusions 521a and the upper part of the fastening hook 404 are triangularly shaped, a catching protrusion 521a can easily fall out of the fastening hook 404 when the bushing 520 is kicked with sufficient force. In the first exemplary embodiment according to the present invention, the male thread 522 and the female thread 403a are formed as left-hand threads. The male thread 522 is loosened when it rotates clockwise with respect to its front surface and tightened when it rotates counterclockwise. When the bushing 520 is fully attached to the housing mounting member 403 (first step), the catching protrusion 521a is arranged to be immediately to the right of the fastening hook 404.

[0063] Thus, the catching projection 521a can prevent the penetrating thread 522 from rotating clockwise and thereby loosening. That is, when the bushing 520 is in a state corresponding to the first step, the position of the bushing 520 is fixed by the fixing hook 404.

[0064] Also, even if vibrations occur during delivery and the bushing 520 rotates in a direction that would cause it to come loose, the bushing 520 can be prevented from moving from its initial position. Another advantage is that it is easy for a worker to recognize the initial position of the bushing 520 during assembly.

[0065] If, unlike described above, the male thread 522 and the female thread 403a are right-hand threads, the catch projection 521a is arranged immediately to the left of the fastening hook 404 because the male thread 522 would loosen upon counterclockwise rotation. A distance adjustment hole 523 is formed to pass through the first washer part and the male thread 522 from front to rear.

[0066] As in Fig. 5, the inner diameter of the clearance adjustment hole 523 is larger than the outer diameter of the screw 510 inserted into the clearance adjustment hole 523. Thus, because the bushing 520 can move in the direction of the outer diameter of the screw 510 within the clearance adjustment hole 523, errors in the longitudinal right-hand direction and in the vertical direction can be corrected.

[0067] The nut 530 includes a second washer part 531 and a connecting part 532 which is connected to a surface of the second washer part 531.

[0068] The outer diameter of the second washer portion 531 is larger than the inner diameter of the clearance adjustment hole 523 of the bushing 520, and a female thread is formed on the inside of the connecting portion 532 so that the connecting portion 532 can be connected to the threaded portion 512 of the screw 510. The female thread of the connecting portion 532 can be a standard thread formed with a lead angle of 5° or less. Thus, the nut 530 does not move forward past the bushing 520.

[0069] In the following, with reference to the Fig. 6 to Fig. 8 describes a method for adjusting the distances between the door frame 100 and the cabinet 400 in both the left-right direction and the front-to-back direction as well as in the vertical direction using the distance adjusting unit 500.

[0070] As in Fig. 6, the socket 520, when in a state corresponding to the first step, is fully attached to the housing mounting member 403 and positioned as far back as possible.

[0071] The screw 510, which is fixed to the door mounting member 150, which in turn is fixed to the door frame 100 in both the vertical and left-right directions, is inserted into the distance adjustment hole 523 of the bushing 520.

[0072] A first clearance G1 is formed between the back side of the screw 510 and the inner side surface of the clearance adjustment hole 523. That is, even if a position at which the case mounting member 403 is mounted deviates in the vertical direction or in the left-right direction based on the position of the door mounting member 150, if the difference is smaller than the first clearance G1, the position of the case mounting member 403 can be adjusted within the first clearance G1, and the difference can be corrected.

[0073] Then, as in Fig. 7, the nut 530 is connected to the back of the screw 510. This is referred to as the second step. Due to the difference between the angles at which the threads of the nut 530 and the bushing 520 are formed, the pitch of the bushing 520 is higher than the pitch of the nut 530. Therefore, when a force is applied to the bushing 520 in the longitudinal direction of the bushing 520, the bushing 520 rotates along the threads and moves in the longitudinal direction of the bushing 520.

[0074] Accordingly, when the nut 531 is rotated so that the front surface of the nut 530 abuts the rear surface of the bushing 520, due to a force generated in the forward direction as the nut 530 rotates, the bushing 520 rotates around itself and moves forward. In this case, the distance between the front surface of the bushing 520 and the front surface of the housing mounting member 403 is referred to as distance G2, and a tolerance in the forward-backward direction can be corrected by adjusting the second distance G2. As shown in Fig. As shown in Figure 8, when the bushing 520 abuts the door mounting member 150, the bushing 520 stops moving forward. Then, the nut 530 is tightened and secured with a tightening torque, and the housing mounting member 403 is attached to the bushing 520, thus fixing it in its final position. This is referred to as the third step.

[0075] In describing the first exemplary embodiments of the present invention, the assembly process was divided into three steps to facilitate understanding, but because the entire process is actually carried out almost simultaneously, the work efficiency of a worker is significantly improved.

[0076] After each housing mounting element 403 has been mounted, the three mounting elements 403 prevent the housing 400 from twisting relative to the socket 520.

[0077] If the screw 510 has a right-hand thread, the nut 530 is tightened when turned clockwise and loosened when turned counterclockwise.

[0078] In the third step, in a case where the bushing 520 has a left-hand thread, when the nut 530 is rotated clockwise and tightened, the bushing 520 is also rotated clockwise by a few degrees due to frictional forces, and thus the housing mounting member 403 is further pressed against the door mounting member 150. That is, an additional force is exerted on the door mounting member 150 via the bushing 520.

[0079] In contrast, in a case where the bushing 520 has a right-hand thread, when the nut 530 is turned clockwise and tightened, the bushing 520 rotates counterclockwise and moves in a direction that separates the bushing 520 from the door mounting member 150. The right-hand thread screw can be useful when no load is to be applied to the parts to be joined together. Second embodiment

[0080] As in Fig. 11, a second exemplary embodiment of the present invention relates to a body mounting structure that, when a part 1400 to be mounted on the inside of a vehicle body 1100 is mounted outside the body 1100, enables a distance between the body 1100 and the part 1400 to be adjusted.

[0081] Examples of part 1400 are a headlight, a sunroof, and the like.

[0082] As in Fig. 12, fastening holes with an open back are formed on the left and right sides of an upper portion of the part 1400 and on the left and right sides of a lower portion of the part 1400.

[0083] A receiving thread 1401 is formed in each of the mounting holes. The threads of the receiving thread 1401 can run at an angle of 30° or more.

[0084] Body mounting parts 1150, each arranged at a location corresponding to a receiving thread 1401 and connected to the associated receiving thread 1401, are attached to the back of the part 1400.

[0085] The receiving threads 1401 and the body mounting parts 1150 are connected to each other by distance adjustment units 1500, which are described in more detail below.

[0086] As in Fig. 12, the body mounting member 1150 is configured similarly to the door mounting member 150 of the first embodiment.

[0087] A screw installation hole 1151 is formed to extend from front to rear through the center of the body mounting member 1150.

[0088] The inner diameter of the screw installation opening 1151 is similar to the inner diameter of a distance adjustment opening 1523 of a bushing 1520, which is described in more detail below.

[0089] As in Fig. 11 to Fig. 13, the body 1100 includes a rear surface plate 1103 and a front surface plate 1104 disposed forward of the rear surface plate 1103 and extending forward from the left and right sides of the rear surface plate 1103, respectively, and then bent to be connected thereto.

[0090] A fastener handling opening 1101 is formed to extend from front to rear through the rear surface plate 1103.

[0091] The handling opening 1101 is configured such that the rear side of the body mounting member 1150 is open to the outside. Thus, a user can manipulate the body mounting member 1150 from the rear side of the body 1100.

[0092] A partial installation opening 1105 is formed to extend through the front surface plate 1104 from front to rear.

[0093] A partial retaining projection 1102 is recessed from front to back on the circumference of the partial installation opening 1105. Due to the partial installation opening 1105, a stepped area is formed on the circumference of the partial installation opening 1105.

[0094] As in the Fig. 11 to Fig. As shown in Figure 13, part 1400 has the overall shape of a rectangular parallelepiped.

[0095] A screw insertion recess 1402 is formed in front of the female thread 1401 of the part 1400. The screw insertion recess 1402 has a cylindrical shape, and a second screw head 1512 of a screw 1510, which will be described in more detail below, is inserted therein. The inner diameter of the screw insertion recess 1402 is smaller than the inner diameter of the female thread 1401, and a male thread 1522 of the bushing 1520, which will be described in more detail below, is not inserted into the screw insertion recess 1402.

[0096] A screw retention recess 1403 is formed in front of the screw insertion recess 1402. The screw retention recess 1403 has the shape of a rectangular prism, and a first screw head 1511 of the screw 1510, which will be described in more detail below, is inserted therein. The screw retention recess 1403 is sufficiently small to prevent rotation of the first screw head 1511.

[0097] The receiving thread 1401, the screw insertion recess 1402, and the screw retaining recess 1403 communicate with each other. A catch projection 1404 is formed on the periphery of the front side of the part 1400 so as to protrude outward. The catch projection 1404 is inserted into the stepped portion formed due to the part retaining projection 1102 of the body 1100. That is, the part retaining projection 1102 is positioned behind the catch projection 1404. Thus, the catch projection 1404 cannot move rearward beyond the part retaining projection 1102.

[0098] A distance adjustment unit 1500 is described in detail in the Fig. 11 to Fig. 13 shown.

[0099] The distance adjustment unit 1500 includes a bushing 1520 that is attached to the receiving thread 1401 of the part 1400, and the screw 1510 that is connected to a nut 1530 through the bushing 1520 and the body mounting member 1150.

[0100] The screw 1510 includes the first screw head 1511 and the second screw head 1512 and a threaded portion 1513 formed to protrude from the surface of the second screw head 1512.

[0101] The first screw head 1511 has the shape of a rectangular prism. The first screw head is inserted into the screw-retaining recess 1403 of part 1400 and serves to prevent rotation of the screw 1510.

[0102] The second screw head 1512 is formed behind the first screw head 1511.

[0103] The threaded portion 1513 may be a standard thread, and the threads of the threaded portion 1513 may be at an angle of 5° or less.

[0104] The bushing 1520 includes a first washer portion 1521, and the male thread 1522 is formed forward of the first washer portion 1521 and secured to the female thread 1401.

[0105] The outer diameter of the first washer part 1521 is larger than the inner diameter of the receiving thread 1401.

[0106] The distance adjustment hole 1523 is formed to pass through the first washer part 1521 and the penetrating thread 1522 in the front-to-rear direction.

[0107] As in Fig. 13, the diameter of the distance adjustment hole 1523 is larger than the outer diameter of the screw 1510 inserted into the distance adjustment hole 1523.

[0108] Thus, because the bushing 1520 can move in the direction of the outer diameter of the screw 1510 within the distance adjustment hole 1523 and the screw installation hole 1151, errors in the left-right direction and in the vertical direction can be corrected.

[0109] A screw fixing projection 1524 is formed on the periphery of the distance adjusting hole 1523 so as to protrude around the distance adjusting hole 1523.

[0110] The outer diameter of the second screw head 1512 is larger than the inner diameter of the screw fixing projection 1524, and the outer diameter of the threaded portion 1513 is smaller than the inner diameter of the screw fixing projection 1524. The screw fixing projection 1524 is formed to protrude sufficiently so that the screw fixing projection 1524 prevents the threaded portion 1513 from wobbling in the vertical direction or in the left-right direction.

[0111] In the following, a method for adjusting the distances between the body 1100 and the part 1400 in the left-right direction, in the front-to-rear direction and in the vertical direction using the distance adjusting units 1500 will be described with reference to Fig. 13 described.

[0112] In a state corresponding to a first step, first, the screw 1510 is assembled with the front of the bushing 1520, and the threaded portion 1513 of the screw 1510 is inserted into the distance adjustment hole 1523 of the bushing 1520.

[0113] Then, the first screw head 1511 of the screw 1510 is inserted into the screw retaining recess 1403 of the part 1400 and the bushing 1520 is fully fastened to the receiving thread 1401 and mounted as far forward as possible.

[0114] In this state, the threaded portion 1513 of the screw 1510, which passes through the bushing 1520 and projects rearward, is inserted or fitted into the screw installation hole 1151 of the body mounting member 1150 from front to rear.

[0115] The front end of the screw 1510 is fixed in the vertical direction and in the left-right direction by means of the screw retaining recess 1403, and a first clearance G1 is formed between the back side of the screw 1510 and the inner side surface of the screw installation hole 1151.

[0116] That is, even if a position at which the female thread 1401 is mounted deviates in the vertical direction or in the left-right direction based on the position of the body mounting member 1150, if the difference is smaller than the first distance G1, the position of the screw 1510 can be adjusted within the first distance G1 and the difference can be corrected.

[0117] Here, a distance between the stepped part formed due to the part retaining projection 1102 of the body 1100 and the catching projection 1404 of the part 1400 is referred to as the third distance G3. The part 1400 can be installed at a desired location only if the third distance G3 is secured by a distance equal to or greater than the first distance G1.

[0118] Then, a step in which the nut 1530 is connected to the rear end of the screw 1510 is called a second step.

[0119] When the nut 1530 is rotated, the difference between the angles at which the threads of the nut 1530 and the bushing 1520 extend creates a pitch in the nut 1530 that is smaller than the pitch of the bushing 1520. Thus, due to a force generated in the rearward direction when the nut 1530 rotates, the bushing 1520 rotates by itself and moves rearward. At the same time, the screw 1510 also moves rearward along with the bushing 1520.

[0120] As in Fig. 13, when the bushing 1520 abuts the body mounting member 1150, the bushing 1520 cannot move further rearward.

[0121] Then, the nut 1530 is tightened to a tightening torque, and the shapes of the first screw head 1511 and the screw-retaining recess 1403 prevent the screw 1510 from rotating freely, and the female thread 1401 attached to the bushing 1520 is also fixed in its final position. This is referred to as the third step. Here, the distance from the front surface of the bushing 1520 to the front surface of the part 1400 is referred to as the second distance G2, and any play or tolerance in the front-to-back direction can be corrected by adjusting the second distance G2. Third embodiment

[0122] In a third exemplary embodiment of the present invention, the shapes of the socket 520 and the housing mounting member 403 are modified from the first embodiment.

[0123] In the third exemplary embodiment of the present invention, a description of the details identical to those described above in connection with the first embodiment will be omitted.

[0124] As in Fig. 14 to Fig. 17, a housing mounting member 3403 projecting upward and a housing mounting member 3403 projecting downward are formed on the right side of the housing 3400, and a housing mounting member 3403 projecting leftward is formed on the left side of the housing 3400. That is, three housing mounting members 3403 are formed on the housing 3400.

[0125] A bushing 3520 is mounted on each of the housing mounting members 3403. Each housing mounting member 3403 includes a catch plate 3403b projecting forward and a mounting hole extending from front to rear through the housing mounting member 3403 including the catch plate 3403b.

[0126] The catch plate 3403b has the shape of a disc.

[0127] As in Fig. 17, a catching recess 3403c is formed on the circumference of the catching plate 3403b so as to be recessed towards the inside of the catching plate 3403b.

[0128] A retaining bracket 3524a of the bushing 3520, which will be described in more detail below, is inserted into the retaining recess 3403c. The retaining recess 3403c is formed on the rear side of the retaining plate 3403b.

[0129] A corner on the front of the catch recess 3403c and the catch plate 3403b is rounded.

[0130] A receiving thread 3403a is formed in the mounting hole. The receiving thread 3403a is formed in the center of the catch plate 3403b.

[0131] The threads of the female thread 3403a can run at an angle of 30° or more.

[0132] The bushing 3520 includes a first washer portion 3521 and a male thread 3522 formed behind the first washer portion 3521 and secured to the female thread 3403a of the housing mounting member 3403.

[0133] The outer diameter of the first washer part 3521 is larger than the inner diameter of the receiving thread 3403a.

[0134] Furthermore, two catch brackets 3524 are formed on the first washer part 3521.

[0135] The catch brackets 3524 are arranged to the left of the circumference of the first washer part 3521 so that they are spaced from each other.

[0136] The catch brackets 3524 are formed such that they protrude from the periphery of the first washer part 3521 in the direction of the outer diameter of the first washer part 3521 and then bend backward. That is, each of the catch brackets 3524 is L-shaped. Each of the catch brackets 3524 protrudes sufficiently far in the direction of the outer diameter of the first washer part 3521 to allow the catch bracket 3524 to wrap around the catch plate 3403b of the housing mounting member 3403.

[0137] As in Fig. 16, a catching projection 3524a is formed at the rear end of each catching bracket 3524 so as to protrude inward.

[0138] The catch projection 3524a is inserted into the catch recess 3403c of the housing mounting unit 3403.

[0139] One corner of the catch projection 3524a is rounded. Since the corner of the catch projection 3524a and the corner on the front side of the catch plate 3403b are rounded, the catch projection 3524a can more easily exit the catch recess 3403c when the bushing 3520 is rotated by applying a sufficiently large force.

[0140] When the socket 3520 is mounted on the housing mounting unit 3403 so as to be positioned as far back as possible, the catching projection 3524a is formed to have a predetermined distance from the front surface of the catching recess 3403c.

[0141] When vibration occurs during delivery and the bushing 3520 rotates and moves forward in a release direction, the catch projection 3524a contacts the front surface of the catch recess 3403c. Then, the rotation of the bushing 3520 is blocked due to a frictional force generated between the catch projection 3524a and the front surface of the catch recess 3403c. Thus, the bushing 3520 can be prevented from moving away from its initial position.

[0142] The present invention has been described above with reference to exemplary embodiments, but those skilled in the art can change or modify the present invention in various ways within the scope of protection without departing from the spirit and scope of the present invention as defined by the following claims.
