Description

  The present invention relates to an air-conditioning register that changes the direction of air-conditioning air that is sent from an air-conditioning apparatus and blows out into a room using fins.

  An air conditioning register for blowing out air for air conditioning sent from an air conditioner is incorporated in an instrument panel or the like of a vehicle (see, for example, Patent Document 1). As shown in FIG. 20, the air conditioning register includes a retainer 132 having an air passage 131 for air for air conditioning. The retainer 132 includes a cylindrical retainer main body 133 and a decorative panel 141 such as a bezel disposed at the downstream end of the ventilation path 131 in the air-conditioning air flow direction.

  On the surface of the left and right wall part 134 of the retainer body 133 on the side of the ventilation path 131, a locked part 135 made of a concave part is provided. In the retainer main body 133, a plurality of fins 136 extending in the left-right direction are arranged in a state of being separated from each other in the vertical direction. Fin shafts 137 are provided at both ends of each fin 136 in the left-right direction. The plurality of fins 136 are supported so as to be tiltable with respect to both wall portions 134 via a pair of shims 138 disposed on the left and right sides thereof. Both shims 138 are made of a softer material than the retainer 132. A locking portion 139 made of a protrusion is provided on the surface of each shim 138 opposite to the ventilation path 131. Then, when the locking portion 139 is locked to the locked portion 135, a pair of left and right shims 138 sandwiching the fin 136 is assembled to the retainer body 133.

  The decorative panel 141 is assembled to the retainer body 133 by claw fitting or the like from the downstream side in the flow direction. The decorating panel 141 has an air-conditioning air outlet 142. Moreover, the downstream end surface 143 in the said flow direction of the decorating panel 141 comprises a part of design surface of the register | resistor for an air conditioning.

  According to the air-conditioning register, the air-conditioning air is blown out from the air outlet 142 after flowing along the fins 136. Therefore, by tilting the fin 136, the direction of the air-conditioning air blown from the blowout port 142 can be changed.

  Further, when the fins 136 are tilted, a sliding resistance is applied from the shim 138 to the fin shafts 137. Therefore, the load when tilting the fin 136 is adjusted to an appropriate magnitude. In addition, when the fin 136 moves in the left-right direction, it hits the shim 138, so that it is possible to suppress the occurrence of a hitting sound as compared with the case where it directly hits the wall portion 134.

Japanese Patent No. 3999153

  By the way, the conventional air-conditioning register may be manufactured at two manufacturing bases (a first manufacturing base and a second manufacturing base). In the first manufacturing base, a product (intermediate product) in a form before the decorative panel 141 is assembled to the retainer main body 133 is manufactured. In the second manufacturing base, the decorative panel 141 is assembled to the retainer body 133 of the intermediate product.

  In this case, the intermediate product is transported from the first manufacturing base to the second manufacturing base, but the shim 138 is bent by an impact or the like when the intermediate product is loaded or unloaded, and the locking portion 139 is locked. There is a possibility that both shims 138 come off the retainer main body 133 with the fins 136 from the part 135.

  This invention is made | formed in view of such a situation, The objective is to provide the register | resistor for an air conditioning which can suppress the omission of the shim from a retainer main body.

  An air-conditioning register that solves the above-described problems constitutes a main part of a retainer having a ventilation path for air-conditioning air, and includes a pair of first wall sections facing each other as four wall sections surrounding the ventilation path, and a relative A retainer body having a pair of second walls facing each other, a pair of first shims arranged facing the ventilation path and adjacent to each first wall, and facing the ventilation path; A pair of second shims arranged adjacent to each second wall portion, and downstream fins extending in the opposing direction of both first shims and supported tiltably by both first shims by fin shafts at both ends And an upstream fin extending upstream of the downstream fin in the flow direction of the air-conditioning air in a direction in which both the second shims face each other and supported by the second shims so as to be tiltable by the fin shafts at both ends. An air-conditioning register, both first shims and The second shim is arranged to form a quadrangular frame, and each of at least three corners of the quadrangular frame has a connection structure that connects the ends of the first shim and the second shim adjacent to each other. A locking portion provided on at least one of the outer surfaces of both the first shims and the two second shims in the square frame body is provided on the outer surface of both the first wall portions and the two second wall portions. It is locked to the locked portion provided on the adjacent wall portion.

  According to the above configuration, the square frame has four corners, and the ends of the first and second shims adjacent to each other are connected to each other by at least three of the corners. Connected. With these connections, the square frame body can easily maintain the initial shape. And the latching | locking part provided in at least one among the outer surface of both the 1st shims and both the 2nd shims in a square frame is adjacent to the said outer surface among both 1st wall parts and both 2nd wall parts. Locked to the locked portion provided on the wall. By this locking, the square frame body on which the upstream fin and the downstream fin are supported is assembled in the retainer body. At this time, since the square frame body can easily maintain the initial shape, the work of assembling the square frame body supporting the upstream fin and the downstream fin in the retainer body is easy.

  In a state where the rectangular frame is assembled in the retainer body, the first wall portion is located adjacent to the side away from the ventilation path of each first shim. The rectangular frame body is restricted from being bent further to the side away from the ventilation path by contacting the first wall portion.

  Moreover, in said state, the 2nd wall part is located adjacent to the side away from the ventilation path of each 2nd shim. The rectangular frame body is restricted from being bent further to the side away from the ventilation path by contacting the second wall portion.

  Moreover, in the corner | angular part in which the connection structure was provided among square frame bodies, the edge parts of the adjacent 1st shim and 2nd shim are connected. Therefore, one or both of the end portions of the first shims and the second shims adjacent to each other are restricted from being bent toward the side approaching the other end portion. In connection with this, it is controlled that the intermediate part in the length direction of each 1st shim bends to the ventilation path side, or the intermediate part in the length direction of each 2nd shim bends to the ventilation path side.

  Further, even if there is a corner portion of the square frame that is not provided with a connection structure, one or both of the end portion of the first shim and the end portion of the second shim that are adjacent to each other are closer to the other end portion. To be bent. This is because, in the first shim, even if one end is not connected by the connecting structure, the other end is connected by the connecting structure to the second shim. Moreover, in the second shim, even if one end is not connected by the connecting structure, the other end is connected by the connecting structure to the first shim.

  Thus, in the square frame, both the pair of first shims and the pair of second shims are not easily bent, and the initial shape of the square frame is easily maintained. The state in which the locking portion of the square frame is locked to the locked portion of the retainer body is easily maintained. As a result, the rectangular frame body assembled in the retainer main body is restricted from falling off from the retainer main body.

  In the air conditioning register, the connection structure bends the ends of the first shim and the second shim adjacent to each other in the length direction and the flow direction of the first shim and the second shim. It is preferable to provide a main coupling structure that couples in a state where the above is regulated.

  According to said structure, both the 1st shims and both 2nd shims which were mutually adjacent | abutted and were connected by the main connection structure in both the length direction and the flow direction of air-conditioning air It is restricted from bending. By this restriction, the first shim and the second shim that are adjacent to each other and connected by the main connection structure are restricted from being separated in any direction.

By this sandwiching, one of the first shim and the second shim provided with the main connection structure between the adjacent end portions is restricted from bending in the length direction of the connection side shim.

  Furthermore, the claw part which protrudes toward the connection side edge part from the said arm part is engaged with the to-be-engaged part opened in the surface facing the claw part of a protrusion part. By this engagement, one of the first shim and the second shim provided with the main connection structure between the adjacent end portions is in the length direction of the connected shim and in the flow direction of the air-conditioning air. Is also restricted from bending.

  In the air-conditioning register, the main connection structure is provided at three corners of the rectangular frame body, and the first shim and the first adjacent to the corner where the main connection structure is not provided. An auxiliary connection structure is provided for connecting the end portions of the two shims in a state in which bending of the first shim and the second shim in the lengthwise direction is restricted, and the main connection structure and the auxiliary connection are provided. It is preferable that the connection structure is constituted by a structure.

  According to said structure, in the corner | angular part in which the auxiliary | assistant connection structure was provided in the square frame, one side of the 1st shim and the 2nd shim which were mutually adjacent | abutted and was connected by the auxiliary | assistant connection structure to the other On the other hand, bending in the length directions of the first shim and the second shim is restricted.

  Therefore, the bending of the first shims and the second shims is more restricted than when the main connection structure is provided only at the three corners of the square frame and the auxiliary connection structure is not provided at one corner. Is done. The square frame body is easily maintained in the initial shape, and the locking portion is easily maintained in a state of being locked to the locked portion. The rectangular frame body assembled in the retainer main body is further restricted from falling off from the retainer main body.

  In the air conditioning register, the auxiliary connection structure includes one end of an end connected to the second shim in the first shim and an end connected to the first shim in the second shim. Extending toward the other end and overlapping with the other end at the upstream or downstream in the flow direction, and provided on the other end and provided on the protrusion It is preferable to include a fitting portion that is fitted to the fitting portion from the upstream side or the downstream side in the flow direction.

  According to said structure, in the corner | angular part in which the auxiliary | assistant connection structure was provided in the square frame, the protrusion piece extended toward the other edge part from one edge part of an adjacent 1st shim and 2nd shim is the said. It overlaps with the other end in the upstream or downstream in the flow direction of the air-conditioning air.

<Shut damper 110>
As shown in FIGS. 4, 7, and 10, the shut damper 110 has a substantially rectangular flat plate shape, and is disposed upstream of the upstream fins 56 and 57 in the retainer body 12. A damper shaft 111 is formed at the left end of the shut damper 110 and at the center in the flow direction. Further, a damper shaft 112 is inserted into the shaft hole 21 of the first wall portion 14 on the right side, and this is the right end portion of the shut damper 110 and is attached to the central portion in the flow direction. The damper shaft 112 is integrated with the damper shaft 113 in the air conditioning register 10 on the right side. The shut damper 110 is supported by both first wall portions 13 and 14 by both damper shafts 111 and 112. The shut damper 110 can tilt between an open position and a closed position with both damper shafts 111 and 112 as fulcrums. In the open position, the shut damper 110 is in a central portion between the second wall portions 15 and 16 and is in a state parallel to or close to the second wall portions 15 and 16 (see the solid line in FIG. 4). Open the ventilation path 20 fully. In the closed position, the shut damper 110 is inclined with respect to the second wall portions 15 and 16 (see the two-dot chain line in FIG. 4) and closes the ventilation path 20.

<Damper drive mechanism 114>
As shown in FIGS. 3, 5, and 10, the damper drive mechanism 114 includes an operation dial 115 and a rotation transmission unit 116. The operation dial 115 is rotatably supported by the shaft portion 22. A shim 120 is attached to the operation dial 115, and the shim 120 is in elastic contact with the shaft portion 22. Due to this form of contact, when the operation dial 115 is turned, a sliding resistance is generated between the shim 120 and the shaft portion 22, and an appropriate load is applied.

  The rotation transmitting unit 116 is for transmitting the rotation of the operation dial 115 to the damper shaft 112, and is constituted by a link mechanism. That is, the damper shaft 112 has a protruding portion 117 that protrudes radially outward. The operation dial 115 also has a protruding portion 118 that protrudes radially outward. Both protrusions 117 and 118 are connected by a link member 119.

The operation dial 115 also serves as an operation dial in the air conditioning register 10 on the right side.
In the air-conditioning register 10 of the present embodiment configured as described above, as shown by a two-dot chain line in FIG. 4, when the shut damper 110 is in the closed position, the ventilation path 20 is blocked by the shut damper 110. . The flow of the air conditioning air A1 in the ventilation path 20 is blocked, and the blowing of the air conditioning air A1 from the air outlet 28 is stopped.

  On the other hand, as shown by a solid line in FIG. 4, when the shut damper 110 is in the open position, each ventilation path 20 is fully open, and the air for air conditioning A1 flows separately on the upper and lower sides with the shut damper 110 as a boundary. The air conditioning air A1 that has passed through the shut damper 110 flows through the ventilation path 20 from upstream to downstream. The air-conditioning air A1 flows along the upstream fins 56 and 57, then flows along the downstream fins 51 and 52, and is blown out from the outlet 28.

  Switching of the shut damper 110 from the closed position to the open position, and switching from the open position to the closed position are performed through a turning operation of the operation dial 115. When the operation dial 115 is rotated by the occupant, the rotation is transmitted to the damper shaft 112 via the rotation transmitting portion 116, and the shut damper 110 is tilted with the damper shafts 111 and 112 as fulcrums.

  4 and 5, when the operation knob 65 is slid leftward or rightward along the downstream fin 51, the movement of the operation knob 65 is transmitted to the upstream fin 56 through the fork 68 and the transmission shaft portion 61. The The upstream fins 56 are tilted in the same direction as the sliding direction of the operation knob 65 with both fin shafts 58 as fulcrums. The tilt of the upstream fin 56 is transmitted to all other upstream fins 57 via the link mechanism LM2. As a result, in conjunction with the upstream fin 56, all the other upstream fins 57 are tilted in the same direction as the upstream fin 56 with the two fin shafts 58 as fulcrums. The flow direction of the air for air conditioning A1 is changed by the tilted upstream fins 56 and 57.

  On the other hand, when a force directed upward or downward is applied to the downstream end portion of the operation knob 65, the force is transmitted to the downstream fin 51 to which the operation knob 65 is attached. The downstream fin 51 is tilted about the fin shaft 53 as a fulcrum. The tilt of the downstream fin 51 is transmitted to all the remaining downstream fins 52 through the link mechanism LM1. As a result, in conjunction with the downstream fin 51 operated through the operation knob 65, all the remaining downstream fins 52 are tilted in the same direction as the operated downstream fin 51 with the fin shaft 53 as a fulcrum. The flow direction of the air for air conditioning A1 is changed by the tilted downstream fins 51 and 52.

  The air-conditioning air A <b> 1 flows in a direction corresponding to the inclination of the upstream fins 56, 57 and the downstream fins 51, 52 and is blown out from the outlet 28. In this way, the direction of the air-conditioning air A1 blown out from the outlet 28 is changed by tilting at least one of the upstream fins 56, 57 and the downstream fins 51, 52.

  Here, when the downstream fins 51 and 52 are tilted, a sliding resistance is generated between each fin shaft 53 and the inner wall surface of the shaft hole 36. Due to this sliding resistance, a load (operation load) for tilting the downstream fins 51 and 52 is created. Further, when the downstream fins 51 and 52 move leftward or rightward, they hit the first shims 31 and 32. Both the first shims 31 and 32 are made of a softer material than the first wall portions 13 and 14. Therefore, the generation of hitting sound is suppressed as compared with the case where the downstream fins 51 and 52 directly contact the first wall portions 13 and 14.

  Further, when the upstream fins 56 and 57 are tilted, a sliding resistance is generated between the pair of fin shafts 58 and the inner wall surface of the shaft hole 42. Due to this sliding resistance, a load (operation load) for tilting the upstream fins 56 and 57 is created. Further, when the upstream fins 56 and 57 move upward or downward, they hit the second shims 33 and 34. Both the second shims 33 and 34 are made of a softer material than the second wall portions 15 and 16. Therefore, the occurrence of a hitting sound is suppressed as compared with the case where the upstream fins 56 and 57 directly contact the second wall portions 15 and 16.

Next, the operation and effect of the air conditioning register 10 of the present embodiment configured as described above will be described.
The assembly of the wind direction changing module 30 to the retainer body 12 is performed as follows, for example. As shown in FIGS. 10 and 11, the wind direction changing module 30 is inclined with respect to the flow direction so that the first shim 32 on the right side is located upstream of the first shim 31 on the left side. The retainer body 12 is inserted from the downstream side. The locking portion 37 of the first shim 32 on the right side is engaged with the locked portion 18 (hole) of the first wall portion 14 on the right side, and the first shim 31 on the left side is upstream with the engagement position as a fulcrum. The entire wind direction changing module 30 is rotated so as to move to the side. As this rotation progresses, the locking portion 37 (see FIG. 17) of the left first shim 31 approaches the locked portion 17 of the left first wall 13 and the two shims 33 and 34 The locking portions 43 and 44 enter the downstream portion in the retainer body 12.

  Each locked portion 17 opens at the downstream end in addition to the right side surface. Therefore, when the wind direction changing module 30 is rotated as described above, the locking portion 37 in the first shim 31 is engaged with the locked portion 17 from the opening portion at the downstream end. Further, with the rotation described above, the locking portions 43 and 44 enter the retainer body 12 while elastically deforming the locked portion 23 and engage with the holes. Further, the engaging protrusions 19 of the first wall portions 13 and 14 are fitted into the engaging holes 39 of the corresponding first shims 31 and 32. Further, the engagement protrusions 24 of the second wall portions 15 and 16 are fitted into the engagement holes 46 of the second shims 33 and 34 facing each other. Then, as shown in FIG. 1, the wind direction changing module 30 is assembled in the downstream portion in the retainer body 12.

  Here, as shown in FIG.1 and FIG.11, the square frame body 35 provided with a pair of 1st shims 31 and 32 and a pair of 2nd shims 33 and 34 has four corner | angular parts C1-C4, Of these, three corner portions C1, C2, and C4 are provided with main connection structures 75, 85, and 95, respectively, and one corner portion C3 is provided with an auxiliary connection structure 105. The ends of the adjacent first shims 31 and 32 and the second shims 33 and 34 are connected to each other by the main connection structures 75, 85 and 95 and the auxiliary connection structure 105.

  That is, as shown in FIGS. 12 and 19, in the upper left corner C <b> 1 of the square frame 35, the protruding portion 82 in the coupled portion 81 is formed by the arm portion 78 and the coupling side end portion 33 </ b> L in the coupling portion 76. It is sandwiched from both left and right sides. By this sandwiching, one of the first shim 31 and the second shim 33 is restricted from bending in the left-right direction with respect to the other. Further, when the claw portion 79 is engaged with the engaged portion 83, one of the first shim 31 and the second shim 33 bends in the vertical direction or the flow direction of the air conditioning air A1 with respect to the other. Be regulated.

  As shown in FIGS. 11 and 13, in the upper right corner C <b> 2 in the square frame 35, the protruding portion 92 in the coupled portion 91 is formed on the left and right sides by the arm portion 88 and the coupling side end portion 33 </ b> R in the coupling portion 86. Sandwiched between. By this sandwiching, one of the first shim 32 and the second shim 33 is restricted from bending in the left-right direction with respect to the other. Further, when the claw portion 89 is engaged with the engaged portion 93, one of the first shim 32 and the second shim 33 bends in the vertical direction or the flow direction of the air conditioning air A1 with respect to the other. Be regulated.

  As shown in FIGS. 11, 15, and 16, in the lower right corner portion C <b> 4 of the square frame body 35, the protruding portion 102 in the coupled portion 101 has an arm portion 98 and a coupling side end portion 34 </ b> R in the coupling portion 96. Is sandwiched from both the left and right sides. By this sandwiching, one of the first shim 32 and the second shim 34 is restricted from bending in the left-right direction with respect to the other. Further, when the claw portion 99 is engaged with the engaged portion 103, one of the first shim 32 and the second shim 34 bends in the vertical direction or the flow direction of the air conditioning air A1 with respect to the other. Be regulated.

  As shown in FIGS. 11 and 14, in the lower left corner C <b> 3 of the square frame 35, the first shim 31 and the second shim 34 are obtained by fitting the fitting portion 108 into the hole 107 of the protruding piece 106. Is restricted from bending in the left-right direction and the up-down direction with respect to the other. However, one of the first shim 31 and the second shim 34 can bend in the flow direction of the air-conditioning air A1 with respect to the other.

  Accordingly, the square frame 35 is easy to maintain the initial shape, although not as much as the case where the main connection structure is provided in the corner portion C3 in addition to the three corner portions C1, C2, and C4. Therefore, the above-described operation for assembling the wind direction changing module 30 in the retainer body 12 is easy.

  In a state where the wind direction changing module 30 is assembled in the retainer main body 12, the first wall portions 13 and 14 are located adjacent to the first shims 31 and 32 on the side away from the ventilation path 20. The rectangular frame 35 is restricted from further bending toward the side away from the ventilation path 20 by contacting the first wall portions 13 and 14 (see FIG. 19).

  Moreover, in said state, the 2nd wall parts 15 and 16 are located adjacent to the side away from the ventilation path 20 of each 2nd shim 33 and 34. As shown in FIG. The rectangular frame 35 is restricted from further bending toward the side away from the ventilation path 20 by contacting the second wall portions 15 and 16.

  Further, in the rectangular frame body 35, the corners C <b> 1 to C <b> 4 provided with the main connection structures 75, 85, 95 and the auxiliary connection structure 105 are the ends of the adjacent first shims 31, 32 and second shims 33, 34. The parts are connected. Therefore, one or both of the end portions of the adjacent first shims 31 and 32 and the end portions of the second shims 33 and 34 bend toward the side closer to the other end portion (left side, right side, upper side, lower side). Be regulated. Accordingly, an intermediate portion in the vertical direction of each first shim 31, 32 is bent toward the ventilation path 20, or an intermediate portion in the left-right direction of each second shim 33, 34 is bent toward the ventilation path 20. Be regulated.

  In particular, in the corner portions C1, C2, C4 provided with the main connection structures 75, 85, 95 in the square frame 35, the claw portions 79, 89, 99 are engaged portions 83, 93 as described above. , 103 is engaged. By this engagement, one of the first shims 31 and 32 and the second shims 33 and 34 is restricted from bending in the vertical direction or the flow direction of the air conditioning air A1 with respect to the other. By this restriction, the first shims 31 and 32 and the second shims 33 and 34 that are adjacent to each other and connected by the main connection structures 75, 85, and 95 are restricted from being separated in any direction.

  Accordingly, both the pair of first shims 31 and 32 and the pair of second shims 33 and 34 are difficult to bend. The square frame 35 is easy to maintain the initial shape. The state in which the locking portions 37, 43, 44 of the square frame 35 are locked to the locked portions 17, 18, 23 of the retainer body 12 is easily maintained. As a result, even if the intermediate product before the decorative panel 25 is assembled to the retainer main body 12 is conveyed, and impact is applied to the intermediate product during loading and unloading, the latching is different from the prior art. The portions 37, 43, 44 are difficult to come off from the locked portions 17, 18, 23. It is possible to prevent the first shims 31 and 32 and the second shims 33 and 34 from dropping from the retainer body 12.

According to the present embodiment, the following effects can be obtained in addition to the above.
The auxiliary connection structure 105 is provided at the corner C3 where the main connection structures 75, 85, and 95 are not provided.

  Therefore, the main connection structures 75, 85, and 95 are provided only at the three corners C1, C2, and C4 in the rectangular frame body 35, and both the first connection structures are compared to the case where the auxiliary connection structure 105 is not provided at the corner C3. The bending of the shims 31 and 32 and the second shims 33 and 34 can be further restricted. The initial shape of the square frame 35 can be easily maintained, and the state in which the locking portions 37, 43, 44 are locked to the locked portions 17, 18, 23 can be easily maintained. It is possible to further prevent the first shims 31 and 32 and the second shims 33 and 34 from dropping from the retainer body 12.

  The auxiliary connecting structure 105 is configured with a simple configuration such as the projecting piece 106 having the hole 107 and the fitting portion 108, and one of the first shim 31 and the second shim 34 has a length relative to the other. It is possible to restrict bending in the direction (left-right direction and up-down direction).

  -Both the first shims 31 and 32, the two second shims 33 and 34, the upstream fins 56 and 57, the downstream fins 51 and 52, and the like constitute the wind direction changing module 30, and this is assembled to the retainer body 12. .

  Therefore, before the wind direction changing module 30 is assembled to the retainer body 12, the operation knob 65 can be attached to the downstream fin 51, and the transmission shaft portion of the upstream fin 56 is supported by the fork 68 supported by the operation knob 65. 61 can be sandwiched from the left and right sides. Therefore, when the upstream fins 56 and 57 are supported by the second shims 33 and 34 and the downstream fins 51 and 52 supported by the first shims 31 and 32 are separately assembled to the retainer body 12. In comparison, the operation of assembling the operation knob 65 and the fork 68 is facilitated.

In addition, the said embodiment can also be implemented as a modification which changed this as follows.
-As an upstream fin, the thing extended in the flow direction and the left-right direction of air-conditioning air A1 may be used, and as a downstream fin, the thing extended in the flow direction and the up-down direction of air-conditioning air A1 may be used.

A connection structure may be provided only at three corners of the four corners C1 to C4 of the square frame 35.
All of the three connection structures may be configured by the main connection structures 75, 85, and 95, or all may be configured by the auxiliary connection structure 105. Further, a part of the three connection structures may be configured by the auxiliary connection structure 105 and the remaining part may be configured by at least one of the main connection structures 75, 85, and 95.

  In this case, one or both of the end portions of the adjacent first shims 31 and 32 and the end portions of the second shims 33 and 34 move to the side closer to the other end portion even at the corner portion where no connection structure is provided. To be regulated. This is because, in the first shims 31 and 32, even if one end is not connected by the connecting structure, the other end is connected to the second shims 33 and 34 by the connecting structure. Further, even if one end portion of the second shims 33 and 34 is not connected by the connecting structure, the other end portion is connected to the first shims 31 and 32 by the connecting structure. Therefore, the square frame 35 is easy to maintain the initial shape.

-The member which comprises the main connection structure 75,85,95 may be changed into the thing different from the said embodiment.
For example, the first shims 31 and 32 may be connected side shims, and the second shims 33 and 34 may be connected side shims. In this case, the end portions of the first shims 31 and 32 are the connection side end portions, and the connection portions (extension portions, arm portions, and claw portions) are provided at the connection side end portions. The end portions of the second shims 33 and 34 are connected side end portions, and a protruding portion and an engaged portion are provided on the connected side end portion.
