The present invention relates to a roof mount of an air conditioner outdoor unit provided with a pair of support members.

  Conventionally, as a roof stand for an air conditioner outdoor unit, a rear seat plate attached to the high side of the roof, a front seat plate attached to the lower side of the roof, and an air conditioner outdoor unit spanned between the rear seat plate and the front seat plate are used. What is provided with the supporting member to mount is known. In this case, the support member generally includes a horizontally disposed base on which the air conditioner outdoor unit is placed and a stay for supporting the front end portion of the base from below. Moreover, in the roof stand of such an air conditioner outdoor unit, the rear seat plate and the front seat plate are configured so that the contact portions with respect to the roof are always constant with respect to the roof R having different inclination angles. Further, in order to achieve such a configuration, it is generally performed that the rear end portion of the base is rotatably connected to the rear seat plate and the lower end portion of the stay is rotatably connected to the front seat plate. It was broken. As such a thing, there exists patent document 1, for example.

  However, in recent years, a simplified structure of the mounting structure between the support member and the rear seat plate and the mounting structure between the support member and the front seat plate has been started to reduce costs. In these devices, the mounting structures described above are simply fixed without being rotatable. As such a thing, there exists a thing described in the nonpatent literature 1, for example. This will be described with reference to FIGS. In the present specification, the description will be made with the lower side of the roof as the front and the higher side of the roof as the rear.

  FIG. 15 is a perspective view of the roof mount of the air conditioner outdoor unit in an installed state. As shown in this figure, the roof mounting table includes a rear seat plate 101, a front seat plate 102, and a pair of support members 103. The rear seat plate 101 is arranged on the higher side of the inclined roof R, and is arranged with the direction perpendicular to the inclination direction of the roof R as the longitudinal direction. The front seat plate 102 is disposed on the lower side of the roof R, and is disposed with the direction perpendicular to the inclination direction of the roof R as the longitudinal direction. Further, the pair of support members 3 are for mounting an air conditioner outdoor unit, and are spanned between the rear seat plate 101 and the front seat plate 102. The support member 103 sets the angle between the base 104 on which the air conditioner outdoor unit is placed, the stay 105 that supports the front end side of the base 104, and the angle of the roof 104 corresponding to the inclination angle of the roof. The adjusting plate 106 functions as a reinforcing member for the support member 103.

  As shown in FIG. 16, the rear seat plate 101 has a contact wall portion 111 having a shape in which a vertically formed vertical portion 111a and a front end portion 111b extending on the roof R are connected by an arcuate curved surface portion 111c. is doing. The contact wall portion 111 is configured to contact the roof R at the curved surface portion 111c. Further, the rear seat plate 101 has a groove portion 114 whose front and rear are supported by a pair of front and rear wall portions 112 and 113 raised upward from a front end portion 111b extending on the roof R. The groove portion 114 has a sliding portion 114b that houses the head portion 115b of the bolt 115 for attaching the base so as to be slidable in the longitudinal direction, and a screw portion 115a of the bolt 115 formed above the sliding portion 114b. And a slit 114a to be protruded. The support member 103 is attached to the rear seat plate 101 by sliding the bolt 115 attached in this way to a predetermined position and fastening the nut 116. Note that a roof leg 117 is attached to the rear seat plate 101 at a contact portion with the roof R.

  The front seat plate 102 is the same as the rear seat plate 101, and is placed on the roof R while changing the front-back direction. As shown in FIGS. 15 and 17, the front seat plate 102 includes a contact wall portion 121, a wall portion 122, a wall portion 123, a groove portion 124, a bolt 125, a nut 126, and a roof foot 127. These correspond to the contact wall portion 111, the wall portion 112, the wall portion 113, the groove portion 114, the bolt 115, the nut 116, and the roof foot 117 in the rear seat plate 1, respectively. Further, the vertical portion 121a, the curved surface portion 121c, and the tip portion 121b that are constituent elements of the contact wall portion 121 correspond to the vertical portion 111a, the curved surface portion 111c, and the tip portion 111b that are constituent elements of the contact wall portion 111, respectively. Further, the slit 124 a and the sliding portion 124 b of the groove portion 124 correspond to the slit 114 a and the sliding portion 114 b of the groove portion 114. Further, the screw part 125 a and the head part 125 b of the bolt 125 correspond to the screw part 115 a and the head part 115 b of the bolt 115. However, the lower end portion of the stay 105 is attached to the groove portion 124 in the front seat plate 102 as described later. For this reason, the front seat plate 102 has an angle with respect to the roof R as viewed from the side so that the surface of the groove portion 124 that opens the slit 124 a matches the mounting angle of the stay 105. Therefore, this angle changes as the inclination angle of the stay 105 changes.

  As shown in FIG. 15, the base 104 constituting the support member 103 has a belt-like flat wall portion 141 that forms an upper surface, and side wall portions 142 that are formed on both sides of the flat wall portion 141 in the width direction.

  In the conventional roof mounting table having the above-described configuration, the base 104 is not rotatably attached to the rear seat plate 101. However, the following difference is applied to the difference in the inclination angle of the roof R. In the conventional roof mounting table, the contact portion of the roof R is changed in the rear seat plate 101. Further, in the conventional roof mounting table, in the front seat plate 102, the inclination angle of the front seat plate 102 with respect to the horizontal plane about the longitudinal direction of the front seat plate 102 is changed, and the contact portion with the roof R is changed. In this way, the conventional roof mounting table has a simplified structure around the attachment of the base 104 and the rear seat plate 101, and the number of parts is reduced. Therefore, it is possible to reduce the cost as compared with the previous roof mount. However, in the rear end portion of the base 104, a height step 146 is formed in the side wall portion 142 in order to form an attachment portion 145 for attaching the support member 103 to the rear seat plate 101. The load of the air conditioner outdoor unit acts as a bending moment in the vicinity of the step 146 forming the attachment portion 145. For this reason, there is a problem that the strength in the vicinity of the step 146 of the base 104 is reduced by forming the step 146 in the mounting portion 145.

  The present invention has been made in view of such a problem of the conventional product, and allows a support member to be attached with a simple structure by forming a step in a side wall portion of a rear end portion of the support member. Another object of the present invention is to provide a roof mount for an air conditioner outdoor unit that avoids deterioration of the strength of the support member due to the formation of the step.

  The roof stand of the air conditioner outdoor unit according to the first solving means for solving the above-mentioned problems has the following configuration. A rear seat plate that is arranged on the high side of the inclined roof and that is arranged with the direction perpendicular to the inclination direction of the roof as the longitudinal direction, and a rear seat plate that is arranged on the low side of the roof and that is perpendicular to the inclination direction of the roof. A front seat plate disposed as a direction, and a support member that is placed between the rear seat plate and the front seat plate and on which the air conditioner outdoor unit is placed. The rear seat plate includes a mounting wall portion formed substantially horizontally, and a contact wall portion formed integrally with the mounting wall portion and partially in contact with the roof. The support member has a substantially horizontal base for mounting the air conditioner outdoor unit. This base has a flat planar wall portion that is horizontally disposed and a side wall portion that hangs laterally in the width direction of the planar wall portion, and a support member is attached to the rear seat plate at the rear end portion thereof. A first attachment portion for attachment is formed. The first attachment portion forms a low wall portion with a reduced height of the side wall portion by forming a step in the height direction on the side wall portion at the side wall portion of the rear end portion of the base. The low wall portion is placed above the mounting wall portion, and the end portion of the planar wall portion is fixed to the mounting wall portion via the low wall portion. Furthermore, the base and the rear seat plate are formed such that when the first mounting portion is fixed to the mounting wall portion, the lower end surface of the side wall portion in the vicinity of the first mounting portion comes into contact with the contact wall portion. .

  According to the roof mounting table of the air conditioner outdoor unit according to the first problem solving means configured as described above, the first mounting portion has the low wall portion placed above the mounting wall portion, and the low wall portion is interposed therebetween. Since the end of the flat wall portion is fixed to the mounting wall portion, the load acting on the base is supported by the mounting wall portion via the low wall portion and the flat wall portion. Moreover, in the 1st attachment part of a base, since the lower end surface of the side wall part near the 1st attachment part is contact | abutting to the contact wall part, the load which acts on a base is contacted by a contact wall part via a side wall part. Is also supported. Thus, the first mounting portion is formed in a simple structure in which the end portion of the base is placed on the rear seat plate by forming a step in the height direction on the side wall portion at the base end portion. In addition, since the lower end surface of the side wall portion in the vicinity of the first mounting portion is supported by the contact wall portion, it is possible to avoid a decrease in strength of the base rear end portion due to the formation of a step in the first mounting portion. .

  In this case, the following configuration may be adopted. The rear seat plate has a connection wall portion that connects the front end of the attachment wall portion and the front end of the contact wall portion, and is formed into a cylindrical body by the attachment wall portion, the contact wall portion, and the connection wall portion. The contact wall is formed with a first protrusion protruding forward from the connecting wall. Further, the base and the rear seat plate are configured such that when the first mounting portion is fixed to the mounting wall portion, the lower end surface of the side wall portion in the vicinity of the first mounting portion abuts on the first protruding portion of the contact wall portion. The rear end surface of the side wall portion forming the step of the first mounting portion is formed so as to contact the connecting wall portion. If it has these structures, the load which acts on the base will be further reduced by the mounting wall part through the low wall part and the flat wall part, by the contact wall part through the lower end surface of the side wall part, Since it is supported by the connecting wall portion via the rear end surface of the wall portion, it is possible to more reliably avoid a decrease in strength of the base rear end portion due to the formation of a step in the first mounting portion.

  The roof mount of the air conditioner outdoor unit according to the second means for solving the above-mentioned problems has the following configuration. A rear seat plate that is arranged on the high side of the inclined roof and that is arranged with the direction perpendicular to the inclination direction of the roof as the longitudinal direction, and a rear seat plate that is arranged on the low side of the roof and that is perpendicular to the inclination direction of the roof. A front seat plate disposed as a direction, and a support member that is placed between the rear seat plate and the front seat plate and on which the air conditioner outdoor unit is placed. The rear seat plate has a mounting wall portion formed substantially horizontally, a contact wall portion that is integrally formed from the rear end of the mounting wall portion, and is in contact with the roof, and a front end of the mounting wall portion. A connecting wall connecting the front end of the wall. Further, the rear seat plate is formed into a cylindrical body by the mounting wall portion, the contact wall portion, and the connecting wall portion. And this connection wall part has the step part which protrudes ahead. The support member has a substantially horizontal base for mounting the air conditioner outdoor unit. The base has a flat planar wall portion that is horizontally disposed and a side wall portion that hangs laterally in the width direction of the planar wall portion, and a support member is disposed on the rear end of the base. A first attachment portion for attachment to the plate is formed. The first mounting portion forms a low wall portion in which the height of the side wall portion is reduced by forming a step in the height direction on the side wall portion at the rear end portion of the base, and the low wall portion is attached to the first mounting portion. It is configured to be placed above the wall portion and to fix the end portion of the flat wall portion to the mounting wall portion via the low wall portion. Further, the base and the rear seat plate are configured such that when the first attachment portion is fixed to the attachment wall portion, the lower end surface of the side wall portion in the vicinity of the first attachment portion contacts the upper surface of the step portion of the connection wall portion. It is formed to touch.

  According to the roof mounting table of the air conditioner outdoor unit according to the second problem solving means configured as described above, the first mounting portion places the low wall portion above the mounting wall portion, and through the low wall portion. Since the end portion of the flat wall portion is fixed to the mounting wall portion, the load acting on the base is supported by the mounting wall portion via the low wall portion and the flat wall portion. In the first mounting portion of the base, the lower end surface of the side wall portion in the vicinity of the first mounting portion is in contact with the upper surface of the stepped portion of the connecting wall portion, so that the load acting on the base is It is supported by the step of the connecting wall through the lower end surface. Thus, the first mounting portion is formed in a simple structure in which the end portion of the base is placed on the rear seat plate by forming a step in the height direction on the side wall portion at the base end portion. Moreover, since the lower end surface of the side wall portion in the vicinity of the first mounting portion is supported by the upper surface of the step portion of the connecting wall portion, the strength of the rear end portion of the base due to the formation of the step in the first mounting portion is reduced. It can be avoided.

Moreover, in the case of this invention, the lower end surface of a side wall part can be made to contact a step part by setting the position of the step part provided in a connection wall part to match the height of the side wall part of a base. .
Further, in this case, the base and the rear seat plate are such that when the first mounting portion is fixed to the mounting wall portion, the rear end surface of the side wall portion forming the step of the first mounting portion is the connecting wall portion. You may form so that it may contact | abut. In this way, the load acting on the base is further reduced by the mounting wall portion through the low wall portion and the flat wall portion, and by the step portion of the connecting wall portion through the lower end surface of the side wall portion. Since it is supported by the connecting wall portion via the rear end surface of the wall portion, it is possible to more reliably avoid a decrease in strength of the base rear end portion due to the formation of a step in the first mounting portion.

  Further, in the first and second problem solving means, the contact wall portion includes a first protrusion portion protruding forward from the connection wall portion and a second protrusion portion protruding upward from the mounting wall portion. A roof leg covering the outer surface of the contact wall portion may be engaged and attached to the contact portion of the contact wall portion with the roof. If it does in this way, a roof leg can be attached, without forming a complicated engaging part.

  In the first and second problem solving means, at least one rib projecting downward and extending in the longitudinal direction may be provided on the lower surface side of the planar wall portion of the base. In this way, the strength of the base is improved, and further, the strength in the vicinity of the step for forming the first mounting portion is also improved.

  In the first and second problem solving means, it is preferable that the height of the rib in the base and the height of the low wall portion are aligned. In this way, since the load applied to the base can be uniformly supported by the rib and the low wall portion in the first mounting portion, the strength near the step for forming the first mounting portion is further improved. .

  Further, in the first and second problem solving means, the bolt head portion can be slid in the longitudinal direction while protruding the screw portion of the bolt upward on the mounting wall portion of the rear seat plate. A groove portion to be housed may be formed, and the flat wall portion of the first mounting portion of the base may be fixed to the mounting wall portion by this bolt. If it does in this way, the 1st attachment part can be made into a simple structure without a rotation mechanism, making it possible to fix a support member to arbitrary positions in the longitudinal direction of a back seat board.

  Further, in the first and second problem solving means, the front seat plate is the same as the rear seat plate, with the front and rear direction changed, and the support member has a front end portion of the base. It may have a stay that supports from below, and may be configured such that a second attachment portion for attaching the support member to the front seat plate is formed at the lower end portion of the stay. In this way, since the rear seat plate and the front seat plate are made into a common part, the cost can be reduced.

  In this case, the following configuration may be further provided. The stay includes a front wall portion and a side wall portion that hangs laterally in the width direction of the front wall portion. The second mounting portion forms a low wall portion in which the height of the side wall portion is lowered by forming a step portion at the height of the side wall portion at the lower end portion of the stay. The low wall portion is placed in front of the mounting wall portion of the front seat plate, and the end portion of the front wall portion is fixed to the mounting wall portion of the front seat plate via the low wall portion. Furthermore, when the second mounting portion is fixed to the mounting wall portion of the front seat plate, the lower end surface of the side wall portion of the stay in the vicinity of the second mounting portion becomes the connecting wall portion of the front seat plate. It forms so that it may contact | abut. If comprised as mentioned above, in the 2nd attachment part, the load which acts on a stay will be supported by the attachment wall part of a front seat board via the low wall part and flat wall part of a stay. In the second mounting portion, the load acting on the stay is also supported by the connecting wall portion of the front seat plate via the lower end surface of the side wall portion of the stay. Thus, by forming a step in the height direction on the side wall portion at the lower end portion of the stay, a mounting portion having a simple structure in which the front end portion of the support member is placed in front of the front seat plate is formed. Moreover, since the lower end surface of the side wall part near the second attachment part is supported by the connecting wall part, it is possible to avoid a decrease in strength of the lower end part of the stay due to the formation of a step in the second attachment part.

  Further, in this case, the connecting wall portion of the front seat plate has a stepped portion that protrudes upward, and the stay and the front seat plate are provided when the second mounting portion is fixed to the mounting wall portion of the front seat plate. You may form so that the rear end surface of the side wall part which comprises the said level | step difference of 2 attachment parts may contact | abut to the front surface of the step part in the connection wall part of a front seat board. If comprised in this way, since the load which acts on a stay is supported also by the front surface of the step part of the connection wall part of a front seat board, the fall of the intensity | strength of a stay lower end part by having formed the level | step difference in the 2nd attachment part. Can be avoided more reliably.

  In this case, at least one rib projecting rearward and extending in the longitudinal direction may be formed on the rear surface side of the front wall portion of the stay. In this way, the strength of the stay is improved, and further, the strength in the vicinity of the step for forming the second attachment portion is also improved.

  Furthermore, in this case, it is preferable that the height of the rib of the stay and the height of the low wall portion are aligned. In this way, the strength of the stay is improved, and further, the strength in the vicinity of the step for forming the second attachment portion is also improved.

  According to the roof mount of the air conditioner outdoor unit according to the present invention, the load acting on the base is caused by the mounting wall portion via the low wall portion and the flat wall portion, and the contact wall portion via the lower end surface of the side wall portion. Or since it is each supported by the step part of a connection wall part, the fall of the intensity | strength of the base rear-end part by having formed the level | step difference in the 1st attachment part can be avoided.

  As shown in FIGS. 1 to 3, the rear end portion of the base 4 (that is, the first mounting portion 46) is first mounted so that the screw portion 15 a of the bolt 15 for mounting the base 4 protrudes upward. The head portion 15b of the bolt 15 is accommodated in the sliding portion 14b of the groove portion 14 of the seat plate 1, and is slid to a predetermined position. Next, the flat wall portion 41 in the first mounting portion 46 at the rear end portion of the base 4 is placed on the mounting wall portion 11 of the rear seat plate 1 through the rib 43 and the low wall portion 42a. At this time, the screw portion 15 a of the bolt (hexagon bolt) 15 is inserted into the bolt hole 48 of the flat wall portion 41 of the first mounting portion 46. Next, the nut 16 is fastened from above. In this way, the rear end portions (that is, the first attachment portions 46) of the pair of support members 3 are temporarily fixed to the rear seat plate 1. When temporarily fixed in this way, the lower end surface of the side wall portion 42 of the base 4 in the first mounting portion 46 is in contact with the first projecting portion 17 of the contact wall portion 12 in the vicinity of the first mounting portion 46. Supported. Further, the rear end surface of the side wall portion 42 of the base 4 forming the step 47 of the first mounting portion 46 is supported in contact with the outer surface of the connecting wall portion 13 of the rear seat plate 1.

  In addition, as shown in FIGS. 1, 2, and 4, the front end portion (that is, the second mounting portion 84) of the support member 3 is first attached to the thread portion of the bolt (hexagon bolt) 25 for mounting the lower stay 8. The head portion 25b of the bolt 25 is accommodated in the groove portion 24 of the front seat plate 2 so that 25a protrudes forward, and is slid to a predetermined position. Next, the front wall portion 81 of the second mounting portion 84 of the lower stay 8 is placed so as to be along the mounting wall portion 21 of the front seat plate 2 via the rib 82 and the low wall portion 83a. At this time, the screw portion 25 a of the bolt 25 is inserted into the bolt hole 87 of the front wall portion 81 of the second mounting portion 84. Next, the nut 26 is fastened from the front. In this manner, the front end portions (that is, the second attachment portions 84) of the pair of support members 3 are temporarily fixed to the front seat plate 2. When temporarily fixed in this way, the lower end surface of the side wall portion 83 forming the step 85 of the second mounting portion 84 is abutted against and supported by the connecting wall portion 23 of the front seat plate 2.

  The roof mounting table temporarily assembled as described above is lifted on the roof R, and the roof mounting table is placed so that the rear seat plate 1 and the front seat plate 2 are arranged at predetermined positions. Next, the roof legs 19 and 29 are attached to the portions of the rear seat plate 1 and the front seat plate 2 that contact the roof. The roof legs 19 and 29 are attached to the first projecting parts 17 and 27 and the second projecting parts 18 and 28 of the contact wall parts 12 and 22 by engaging the engaging parts at the ends of the roof legs. Next, as shown in FIG. 1, the rear seat plate 1 is held and held on the wall surface of the building by the wire 91. One end of the wire 91 is fixed to the wall surface of the building by a heat nail 92 and the other end is wound around the rear seat plate 1 and fixed. Then, the height of the stay 5 is adjusted so that the base 4 is held horizontally corresponding to the inclination of the roof R. Further, it is confirmed whether the support member 3 is fixed at a predetermined position. The anti-vibration material 44 is fixed to the upper surface of the base 4 in the roof pedestal assembled and installed as described above.

  FIG. 2 is a side view when the inclination angle of the roof R is large, and FIG. 10 is a side view when the inclination angle of the roof R is small. As can be seen from these figures, by increasing the length of the stay 5, it is possible to cope with the roof R having a large inclination angle. At this time, since the base 4 is held horizontally in the rear seat plate 1, the mounting wall 11 is always in the horizontal direction, and the inclination angle with respect to the horizontal plane with the longitudinal direction as viewed from the side is unchanged. Yes. However, when the inclination angle of the roof R changes, the contact portion of the contact wall portion 12 with the roof R changes. On the other hand, the front seat plate 2 which uses the same thing as the rear seat plate 1 changes the inclination angle with respect to the horizontal plane with the longitudinal direction as an axis viewed from the side in response to the change in the mounting angle of the stay 5. . That is, the front seat plate 2 has a large inclination angle with respect to the horizontal surface of the flat surface of the mounting wall 21 when the inclination angle of the roof R is large, and a horizontal surface of the flat surface of the mounting wall portion 21 when the inclination angle of the roof R is small. Rotate about the longitudinal direction as an axis so that the angle of inclination with respect to is small. For this reason, the contact part with the roof in the contact wall part 22 of the front seat board 2 also changes with the inclination angle of the roof R.

According to the roof mount of the air conditioner outdoor unit configured as described above, the following effects can be achieved.
(1) The first mounting portion 46 has a structure in which the end portion of the base 4 is placed on the rear seat plate 1 by forming a step 47 in the height direction on the side wall portion 42 at the rear end portion of the base 4. Therefore, a simple structure can be obtained. In particular, since the end of the base 4 and the rear seat plate 1 in the first mounting portion 46 are fixed by the bolt 15 in which the head portion 15b is housed in the sliding portion 14b of the groove portion 14 of the rear seat plate 1, A simple structure without a rotation mechanism can be obtained. Further, the groove portion 14 accommodates the head portion 15b in the sliding portion 14b and allows the bolt 15 to slide in the longitudinal direction in a state where the screw portion 15a protrudes upward from the slit 14a. The support member 3 can also be fixed at an arbitrary position in the longitudinal direction of the plate 1.

  (2) Similarly, the second mounting portion 84 is also formed with a step 85 in the height direction on the side wall portion of the lower stay 8 at the lower end portion of the stay 5, so that the lower end portion of the stay 5 is connected to the front seat plate 2. Since it is formed as a structure that is placed forward, a simple structure can be obtained. In particular, the lower end portion of the lower stay 8 and the front seat plate 2 in the second mounting portion 84 are fixed by the bolt 25 in which the head portion 25b is housed in the sliding portion 24b of the groove portion 24 of the front seat plate 2. A simple structure without a moving mechanism can be achieved. Further, the groove portion 24 accommodates the head portion 25b in the sliding portion 24b and allows the bolt 25 to slide in the longitudinal direction in a state where the screw portion 25a protrudes upward from the slit 24a. The support member 3 can also be fixed at an arbitrary position in the longitudinal direction 2.

  (3) In the first attachment portion 46, the load acting on the base 4 is supported by the attachment wall portion 11 via the low wall portion 42 a and the flat wall portion 41 of the first attachment portion 46, and the side wall portion 42. Is supported by the contact wall portion 12 through the lower end surface of the side wall portion and is also supported by the connecting wall portion 13 through the rear end surface of the side wall portion 42. For this reason, although the fall of the intensity | strength of the rear-end part of the base 4 by having formed the level | step difference 47 in the 1st attaching part 46 was a problem in a prior art, it is avoided in this invention.

  (4) Similarly, in the second mounting portion 84, the load acting on the stay 5 is supported by the mounting wall portion 21 of the front seat plate 2 through the low wall portion 83 a and the front wall portion 81 of the second mounting portion 84. At the same time, it is also supported by the connecting wall portion 23 via the lower end surface of the side wall portion 83. For this reason, a decrease in strength of the lower end portion of the stay 5 due to the step 85 for forming the second attachment portion 84 is avoided.

  (5) Since the rib 43 that protrudes downward and extends in the longitudinal direction is provided on the lower surface side of the flat wall portion 41 of the base 4, the strength of the base 4 is improved and the first mounting portion 46 is formed. The strength near the step 47 is also improved. Furthermore, since the height of the rib 43 of the base 4 and the height of the low wall portion 42a are aligned, the load applied to the base 4 is supported substantially uniformly by the rib 43 and the low wall portion 42a in the first mounting portion 46. be able to. Thereby, the strength in the vicinity of the step 47 for forming the first mounting portion 46 is further improved.

  (6) Since the rib 82 protruding rearward is formed on the rear surface side of the front wall portion 81 of the lower stay 8, the strength of the lower stay 8 is improved, and further, the second mounting portion 84 is formed. The strength near the step 85 is also improved. Moreover, since the height of the rib 82 and the height of the low wall portion 83a are aligned, the load applied to the stay 5 can be uniformly supported by the rib 82 and the low wall portion 83a in the second mounting portion 84. Therefore, the strength of the stay 5 is improved, and the strength in the vicinity of the step 85 for forming the second mounting portion 84 is also improved.

  (7) The rear seat plate 1 includes an attachment wall portion 11 for attaching the rear end portion of the support member 3, a contact wall portion 12 having a contact portion with the roof R, and a front end portion and a contact wall of the attachment wall portion 11. Since it is formed in the cylindrical body by the connection wall part 13 which connects the front-end part of the part 12, intensity | strength can be enlarged with the simplified structure. Moreover, since the back seat plate 1 is formed in the cylindrical body which integrally formed the groove part 14 for attaching the support member 3, the intensity | strength of the back seat plate 1 improves. In particular, the groove portion 14 is formed at the corner portion of the mounting wall portion 11 and the connecting wall portion 13, and the mounting wall portion 11 and the connecting wall portion 13 and the wall portion forming the groove portion 14 are integrated, The strength of the back seat plate 1 is further improved.

  (8) While the rear seat plate 1 is formed in a cylindrical shape as described above, the upper surface of the mounting wall portion 11 is flat and the groove portion 14 is formed on the inner side of the cylindrical body. Therefore, the mounting structure of the rear end portion of the support member 3 is simplified.

  (9) Since the rear seat plate 1 engages and attaches the roof leg 19 to the first projecting portion 17 and the second projecting portion 18 of the contact wall portion 12 of the rear seat plate 1, a complicated relationship is established. The roof foot 19 can be attached without forming a joint.

(10) The rear seat plate 1 has a good appearance because the groove portion 14 is formed over the entire length in the longitudinal direction of the mounting wall portion 11 and the rear seat plate 1 is extruded using the longitudinal direction as the extrusion direction.
(11) Since the front seat plate 2 has the same structure as that of the rear seat plate 1, the cost can be reduced by sharing the parts. In addition, the rear seat plate 1 is attached to the rear end portion (first attachment portion) of the base 4, whereas the front seat plate 2 is different in that the lower end portion (second attachment portion) of the lower stay 8 is attached. If it does so, the front seat board 2 can show | play the effect similar to the effect of (7)-(10) about the above-mentioned back seat board 1. FIG.

(12) Since the base 4, the stay 5, and the reinforcing member 6 as well as the rear seat plate 1 and the front seat plate 2 are all formed by extrusion using an aluminum material, the weight and appearance are improved.
