Abstract

<P>PROBLEM TO BE SOLVED: To improve executability of work by expanding a degree of freedom of adjusting a position of a door frame, when installing the door frame in a wall opening part of a building. <P>SOLUTION: The door frame is installed in an opening part of the building by using a door frame adjusting tool 30 having a seat plate member 31 fixed to a vertical frame member 11, a plate spring 32 installed in this seat plate member and positioned between the seat plate member and a skeleton 16 of the building, and an adjusting machine screw 33 for fixing the seat plate member to the skeleton in a state of bringing the plate spring into pressure contact with a skeleton surface of the building. An interval adjustment of the vertical frame member 11 to the opening part of a wall is allowed via elastic deformation of the plate spring 32. Holes 37 and 43 having a dimension larger than a body diameter of the adjusting machine screw 33 are formed in the respective centers of the seat plate member 31 and the plate spring 32, and the adjusting machine screw 33 is inserted into these holes, and is screwed in the skeleton of the building, to thereby allow a position adjustment of the vertical frame member 11 in the longitudinal-vertical dislocation direction to the opening part of the wall. Generation of a warp and a bend in the seat plate member by reaction from an elastic member is prevented by arranging a rib 45 in the seat plate member, and the interval adjustment and the position adjustment are not hindered. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a door frame adjustment tool used for adjusting the position of a door frame when a door frame such as a door or a sliding door is attached to a wall opening of a building, and a door frame mounting structure using the door frame adjustment tool. .

As door frame adjusters, for example, those described in Patent Documents 1 and 2 below are known. In these door frame adjusters described in Patent Documents, the position of the door frame is adjusted by using an adjustment screw or a gap adjuster so that the door frame can be moved in the horizontal direction.
Japanese Patent No. 2946210 Japanese Patent No. 3344819

  However, the conventional door frame adjuster adjusts the door frame member by moving it only in the horizontal direction, and it is difficult to perform fine position adjustment, and there is a problem in workability.

  Therefore, the problem to be solved by the present invention is to increase the degree of freedom of position adjustment of the door frame when the door frame is attached to the wall opening of the building and to improve the workability. An object is to provide an adjustment tool and a door frame attachment structure using the door frame adjustment tool.

  In order to achieve the above object, the present invention according to claim 1 is a door frame adjustment tool for positioning a door frame member when fixing the door frame to the opening of the wall. The seat plate member fixed to the housing, the elastic member attached to the seat plate member and located between the building housing and the elastic member is pressed against the building surface of the building, and the seat plate member is fixed to the housing. The elastic member is elastically deformed between the seat plate member fixed to the door frame member and the housing of the building to allow adjustment of the interval of the door frame member with respect to the opening of the wall, In addition, the pressing and fixing means adjusts the position of the door frame member in the front-rear and up-down shifting directions with respect to the opening of the wall in a state where each hole formed in the seat plate member and the elastic member is inserted and fixed to the building frame. It is characterized by allowing.

  According to a second aspect of the present invention, in the door frame adjuster according to the first aspect, the seat plate member is provided with a rib extending in a substantially long side direction.

  According to the third aspect of the present invention, after the door frame member is positioned using the door frame adjusting tool according to the first or second aspect, a spacer is inserted into the gap between the building frame and the door frame. The door frame mounting structure is characterized in that the door frame member is fixed to the housing by a fixing means.

  According to the present invention, the seat plate member is fixed to the building frame in a state where the elastic member is pressed against the building surface of the building via the pressure fixing means. The position (interval) of the frame member can be adjusted. In addition, even when the pressing and fixing means is inserted into the holes formed in the seat plate member and the elastic member and fixed to the housing of the building, it is allowed due to the dimensional difference between the trunk diameter of the pressing and fixing means and the insertion holes. Since the position of the door frame member can be shifted with respect to the housing within the range, it is possible to finely adjust the door frame member by moving it forward and backward and up and down. Further, since the washer of the pressing and fixing means is smaller than the insertion hole of the door frame member, the door frame member can be moved with respect to the adjusting screw within a range allowed by this dimensional difference. In this way, even after the door frame member is fixed to the building frame using the adjustment screw, the position of the door frame with respect to the frame is moved in six directions: front and rear, left and right, and finely adjusted. be able to.

  Therefore, after positioning and mounting the door frame to the opening of the wall, even if the opening housing or door frame is deformed for some reason, the door frame adjustment tool adjustment screw should be tightened or loosened. By doing so, the door frame can be reset and finely adjusted to take an appropriate position with respect to the opening.

  Moreover, the rigidity of the seat plate member is increased by providing the seat plate member with ribs extending in a substantially long side direction while being fixed to the door frame member. That is, when the seat plate member of the door frame adjuster of the present invention is fixed to the door frame member and is elastically deformed, the seat plate member receives the reaction force from the elastic member. Since this reaction force concentrates on the upper and lower ends of the seat plate member to which the elastic member is attached, it tries to bend the seat plate member in a convex shape toward the housing side. Providing the ribs extending in the side direction can prevent the convex warpage from occurring. If convex warpage occurs in the seat plate member, the gap between the housing and the door frame member is narrowed and the substantial adjustment allowance is reduced, but the housing and the door frame member are provided by providing ribs in the above direction. Since a sufficient interval is secured, the spacing can be adjusted in a state where a sufficient adjustment margin is secured. Furthermore, if the seat plate member warps or bends, the door frame member faces in an unexpected direction and the position adjustment becomes unstable. However, the present invention prevents the seat plate member from being warped or bent by providing the rib. Therefore, efficient position adjustment can be performed while maintaining the door frame member at a predetermined position.

  FIG. 1 is a front view of a state in which a door frame is attached to an opening of a wall using door frame adjusters 30 and 30 according to an embodiment of the present invention. The door frame 10 is formed of a pair of left and right vertical frame members (door frame members) 11 and 12 and a horizontal frame member 13 that connects the upper ends of the vertical frame members 11 and 12, and the vertical frame members 11 and 12 win. It is a three-way frame. The vertical frame members 11 and 12 and the horizontal frame member 13 are coupled by a known method. For example, a bolt insertion hole (not shown) extending from the left and right ends of the horizontal frame member 13 to a required length is formed and the bolt A bolt insertion hole (not shown) in which a nut member (not shown) is inserted and fixed so that the insertion hole and the screw hole are aligned, and a bolt member (not shown) is opened at the upper end of the vertical frame members 11 and 12. And it can carry out by screwing in a nut member through the bolt insertion hole of the horizontal frame member 13.

  Casing grooves 14a, 14b, and 14c into which casings 19 (shown in FIG. 8) are fitted are formed on the front and back surfaces of the vertical frame members 11 and 12 and the horizontal frame member 13 so as to extend in the respective longitudinal directions. Cutout portions 15 a and 15 b are formed at the upper ends of the members 11 and 12 for continuing the casing grooves 14 a and 14 b of the vertical frame members 11 and 12 and the casing grooves 14 c of the horizontal frame member 13.

  As shown in FIG. 8, the vertical frame member 11 is fixed to the housing 16 such as a pillar by a fixing screw (fixing means) 20 with a tree 21 having a predetermined thickness e sandwiched between the vertical frame member 11 and the housing 16. Surface plates 22 and 22 are attached to the front and back of the casing 16 to form a wall 23. The casings 19 and 19 are fitted in the casing grooves 14a and 14a of the vertical frame member 11 so as to sandwich the wall 23 from both sides. Worn. A pair of door contact grooves 24 and 24 for fitting a door stop (not shown) are provided on the opening side of the vertical frame member 11 with the fixed screw 20 driven in between. . The head of the fixed screw 20 is concealed by fitting the door stop into the door stop grooves 24 and 24 after driving the fixed screw 20.

  In the door frame 10 having such a configuration, the door frame adjusters 30 and 30 according to the embodiment of the present invention are provided one by one at approximately the center of the vertical frame members 11 and 12 in the height direction. Hereinafter, the door frame adjuster 30 will be described in detail with reference to FIGS. 2 to 7. The door frame adjustment tool 30 described in detail below is provided on the vertical frame member 11, but the door frame adjustment tool 30 provided on the other vertical frame member 12 has the same configuration.

  The door frame adjusting tool 30 includes a seat plate member 31 fixed to the vertical frame member 11, an elastic member 32 fixed to the seat plate member 31, and the seat plate member 31 via the elastic member 32. And an adjustment screw 33 to be fixed to.

The seat plate member 31 is formed of a metal material such as steel, aluminum, zinc, bronze or other arbitrary material in a rectangular shape or a circular shape in plan view, and is in close contact with the surface (outer surface) 17 of the vertical frame member 11 on the housing 16 side. A flat base surface portion 35 fixed together with the plate spring 32 by screws 34, 34, and protrudes from one side of the base surface portion 35 and is fitted into the through hole 18 (having a diameter D ₀ ) of the vertical frame member 11. It has a cylindrical projection 36 and is integrally formed. The inner diameter of the cylindrical protrusion 36, that is, the diameter D ₂ of the screw insertion hole 37 is sufficiently larger than the body diameter of the adjustment screw 33. The height dimension h is a height at which the head of the adjusting screw 33 does not protrude to the front surface side (right side in FIG. 2) of the vertical frame member 11, and can be up to h = 0 (that is, no protrusion) at the minimum. However, considering the ease of work when screwing the adjusting screw 33 from the surface side, the height of the door frame (vertical frame member 11) is about 1/3 to 2/3 of the thickness dimension H. preferable. When the protrusion 36 is not provided (h = 0), the thickness of the seat plate member 31 is increased to ensure the necessary strength. The tip of the cylindrical protrusion 36 is a flat surface.

  Near the upper and lower ends of the base surface portion 35 are formed pin-like projections 38 and 38 that serve as guides when the leaf spring 32 is pressed and deformed (FIG. 3). Each pin-like protrusion 38 is provided with a screw hole (not shown) for allowing the screw 34 to pass therethrough, and the pin 34 is inserted into the long hole 40 of the leaf spring 32 with the pin-like protrusion 38 fitted. The seat plate member 31 can be fixed to the vertical frame member 11 while allowing deformation of the plate spring 32 by screwing the vertical frame member 11 through the screw holes.

  In this embodiment, a cylindrical projection 36 is integrally formed at the center of the seat plate member 31 and is fitted into the through hole 18 of the vertical frame member 11. However, any shape that can be fitted to the vertical frame member 11 is used. For example, the shape of the protrusion is arbitrary. Alternatively, a screw insertion hole 37 that is sufficiently larger than the body diameter of the adjustment screw 33 may be formed in the center of the seat plate member 31 without providing such a projection. Alternatively, a pair of opposing protrusions having a substantially crescent cross-sectional shape may be provided, and a space between the protrusions may be formed at a sufficiently larger interval than the body diameter of the adjustment screw 33 to form the screw insertion hole 37. Further, the screw insertion hole 37 formed to be sufficiently larger than the body diameter of the adjustment screw 33 for inserting the adjustment screw 33 can have an arbitrary shape, and is opposed to a circle, an ellipse, a rectangle, and a rectangle. It is possible to use a deformed rectangle, polygon, or the like in which two sides are replaced with arcs.

The leaf spring 32 used as an elastic member in this embodiment has a rectangular shape in plan view, and has two (or an arbitrary number more than that) arc portions 41, 41 on both sides of a central portion formed in a wave shape. The flat flange portions 42, 42 are used (FIG. 2). Center of the wavy central portion, that is, a rectangular hole 43 having a larger width d than or the same as the diameter D ₂ of the screw insertion hole 37 of at least the seat plate member 31 is provided between the arcuate portion 41 and 41 is provided (FIG. 4). As described above, each flange portion 42 is provided with a long hole 40 into which the pin-like protrusion 38 of the seat plate member base surface portion 35 is inserted. When the leaf spring 32 is not deformed and maintains the normal state, the pin-like projections 38 are positioned on the outer side of the long holes 40, 40 (FIG. 3), but when the leaf spring 32 is pressed and deformed, the pin-like projection 38 38 and 38 move toward the inside of the long holes 40 and 40.

The adjustment screw 33 is inserted into the through-hole 18 of the vertical frame member 11 from the surface side through a washer 44 brought into contact with the flat end of the cylindrical protrusion 36 of the seat plate member 31, and the screw of the seat plate member is inserted. The screw 37 is inserted through the hole 37 and the screw insertion hole 43 of the leaf spring 32 and screwed into the housing 16. The diameter _{D 1} of the washer 44 is greater than the diameter _{D 2} of the screw insertion hole 37, and smaller than the diameter _{D 0} of the through-hole 18 of the vertical frame member 11 (FIG. 4). In this way, the door frame adjustment tool 30 is fixed to the vertical frame member 11 by the screws 34, 34 and is fixed to the housing 16 by the adjustment screw 33, and between the vertical frame member 11 and the housing 16. The distance is adjustable through elastic deformation of the leaf spring 32.

  In order to attach the door frame 10 to the opening portion of the wall 23 using such a door frame adjusting tool 30, the width of the wall opening portion is 10 mm with respect to the size of the door frame 10 in FIG. After the height from 25 is increased by about 5 mm, and the door frame adjusters 30 and 30 are fixed to the vertical frame members 11 and 12 by the screws 34 and 34 in the above-described manner at the approximate center positions in the height direction, respectively. The door frame 10 is disposed on the floor base 25 at the wall opening. The number of door frame adjustment tools 30 is arbitrary. Next, the adjusting screw 33 is screwed in the above-described manner, and the door frame 10 is temporarily fixed at an appropriate position of the wall opening while the vertical frame members 11 and 12 are vertically projected and the horizontal frame member 13 is leveled. At this time, it is preferable that a gap of about 5 mm is formed between the three-way frame members 11, 12, 13 of the door frame 10 and the housing 16. Next, arbitrary positions of the vertical frame members 11 and 12 (in the illustrated embodiment, three positions of an upper portion, a central portion, and a lower portion for each vertical frame member) and arbitrary positions of the horizontal frame member 13 (the left and right sides of the horizontal frame member 13 in the illustrated embodiment) At two locations near both ends, the timbers 21, 21... Have a thickness corresponding to the gap (e = about 5 mm) between the frame 16 (column or horizontal member) and each door frame member. . . Is fixed by the fixing screw 20 (FIG. 8). Further, a floor plate 26 is laid on the floor base 25.

  When the door frame 10 is temporarily fixed at an appropriate position of the wall opening, by using the door frame adjustment tool 30 having the above-described configuration, even when the adjustment screw 33 is screwed into the housing 16, the front / rear / left / right / Subtle position adjustment is possible in the upper and lower six directions. That is, the door frame adjustment tool 30 is fixed to the vertical frame member 11 with the screws 34 and 34 and fixed to the housing 16 such as a column with the adjustment screws 33 in the manner described above. Since the distance between the vertical frame member 11 and the housing 16 can be adjusted through elastic deformation, the position in the left-right direction in FIG. 1 can be adjusted. The leaf spring 32 is in a state (FIG. 3) in which the pin-like protrusions 38, 38 of the seat plate member 31 are accommodated near the outer side of the long holes 40, 40 when not being in pressure contact. The positions of the pin-shaped projections 38, 38 in the long holes 40, 40 move inward. Accordingly, the adjustment allowance in the left-right direction is the movable distance of the pin-like protrusions 38, 38 given by the dimensional difference between the length of the long holes 40, 40 and the diameter of the pin-like protrusions 38, 38.

Further, the adjustment screw 33 for fixing the door frame adjusting tool 30 to the housing 16 is a washer that is inserted through the hole 37 and the hole 43 having a size larger than the body diameter d and is in contact with the flat end surface of the cylindrical protrusion 36. Since the diameter D ₁ of 44 is smaller than the diameter D ₀ of the through hole 18 of the vertical frame member 11, the vertical frame member 11 is slightly smaller than the housing 16 in the front-rear and vertical directions within the allowable range. Adjustment movement is possible. That is, in FIG. 2, the washer 44 has a diameter D ₁ that is sufficiently smaller than the diameter D ₀ of the through hole 18 of the vertical frame member 11, so that the inside of the through hole 18 is moved back and forth (up and down in FIGS. 2 and 3). Since the adjustment screw 33 passes through the screw insertion holes 37 and 43 having a diameter larger than the body diameter d, the adjustment screw 33 is movable in the front-rear direction within the range of the screw insertion holes 37 and 43. Can be moved to. Therefore, even if the adjustment screw 33 is screwed into the housing 16, the vertical frame member 11 is moved in the front-rear direction with respect to the housing 16 within the range allowed by the dimensional difference between the members. The position can be finely adjusted. Further, since the washer 44 can move within the through hole 18 in the screw insertion hole 37 of the seat plate base surface portion 35, even if the adjustment screw 33 is screwed into the housing 16, within this range. The position of the vertical frame member 11 can be finely adjusted by moving the vertical frame member 11 in the vertical direction (the vertical direction in FIG. 2 and the horizontal direction in FIG. 3) with respect to the casing 16.

In FIG. 4, the adjustment screw 33 is screwed and fixed to the housing 16 through substantially the center of the screw insertion holes 37 and 43. When the vertical frame member 11 is moved in the front-rear direction (upward in FIG. 4) relative to the housing 16 from this fixed state, the adjustment screw 33 is inserted into the screw insertion hole of the seat plate member 31 as shown in FIG. The washer 44 is in contact with the peripheral wall surface of the through hole 18 of the vertical frame member 11 at the same time as it is in contact with the peripheral wall surface of 37. The state shown in FIG. 5 is a case where the dimensions d, D ₀ , D ₁ , D ₂ are most appropriately associated with each other, and the adjustment screw 33 is inserted into the screw insertion hole 37 during the movement. FIG. 6 shows a case where the washer 44 has not yet reached the peripheral wall surface of the through hole 18 when it comes into contact with the peripheral wall surface. FIG. 6 shows that the adjustment screw 33 is still in contact with the peripheral wall surface of the through hole 18. The case of the dimensional relationship which does not reach the peripheral wall surface of the screw insertion hole 37 is shown in FIG. In any case, the adjusting screw 33 and the washer 44 are required to be relatively far from the seat plate member 31 and the vertical frame member 11 (for example, 5 mm from the center in each direction, about 10 mm in total) in the front-rear direction. It only has to be able to shift. However, in order to avoid that the outer edge of the washer 44 when shifted to the maximum this way will penetrate the screw insertion hole 37 of the seat plate member 31, the radius of the washer 44 (D _1/2) and the adjusting screw 33 It is necessary to set the sum (a) of the trunk radii (d / 2) to be larger than the hole diameter D ₂ of the seat plate member 31 (a> D ₂ ). Although not shown in detail with reference to the drawings, the same applies to shifting in the vertical direction.

  In the door frame adjustment tool 30 described above, a center formed in a wave shape with two arc portions 41 and 41 as an elastic member for urging the seat plate member 31 in a substantially vertical direction with respect to the housing 16. A plate spring 32 having a trapezoidal side shape is used in the door frame adjuster 30A of the embodiment shown in FIG. 9 instead. When such a leaf spring 32A is used, the flat frame member 11 is easily fixed temporarily while maintaining a parallel relationship with the casing 16 of the opening because the flat spring 32A is in contact with the casing 16 in a plane, and workability is improved. To do. Since other members and portions in the embodiment shown in FIG. 9 are the same as those in the above-described embodiment, they are given the same reference numerals, and description thereof will be omitted.

  Moreover, in the door frame adjustment tool 30B by another embodiment of this invention shown in FIG.10 and FIG.11, the ring-shaped elastic body 32B which consists of a resin foam material is used as an elastic member. The ring-shaped elastic body 32B is disposed between the seat plate member 31 and the housing 16, and the central opening 43B corresponds to the screw insertion hole 43 provided in the leaf spring 32 in the above-described embodiment. Also in this door frame adjustment tool 30B, the elastic body 32B is compressed or expanded by screwing or loosening the adjustment screw 33, and the vertical frame member 11 is adjusted in the left-right direction while maintaining the parallel relationship with the housing 16. Can be temporarily fixed. Note that the seat plate member 31 of this embodiment is disk-shaped, and is provided with pin-like projections 38 and 38 at least at two locations and fixed to the vertical frame member 11 with screws 34 and 34. The cylindrical protrusion 36 as shown in FIG. 2 is not provided on the front surface side of the seat plate member 31, and the center portion on the back surface side is slightly thickened to position the ring-shaped elastic body 32B. . The same reference numerals are given to the same members and parts as those in the above-described embodiment, and the description thereof will be omitted.

  In a door frame adjuster 30C according to still another embodiment of the present invention shown in FIG. 12, a spring coil 32C wound approximately concentrically around an adjustment screw 33 is used as an elastic member. Also in this door frame adjustment tool 30C, the spring coil 32C is compressed or expanded by screwing or loosening the adjustment screw 33, and the vertical frame member 11 is adjusted in the left-right direction while maintaining the parallel relationship with the housing 16. Can be temporarily fixed. The same reference numerals are given to the same members and parts as those in the above-described embodiment, and the description thereof will be omitted.

  In a door frame adjustment tool 30D according to still another embodiment of the present invention shown in FIG. 13, two or more arbitrary number of spring coils 32D are opposed to the adjustment screw 33 around the adjustment screw 33 as an elastic member. It is arranged in a position or substantially concentric. Also in the door frame adjusting tool 30D, the spring coil 32D is compressed or expanded by screwing or loosening the adjusting screw 33, and the vertical frame member 11 can be temporarily fixed by adjusting the position of the vertical frame member 11 in the left-right direction. . In order to maintain the vertical frame member 11 in parallel with the housing 16, it is preferable that the plurality of spring coils 32 </ b> D are arranged substantially concentrically around the adjustment screw 33 at equal intervals. The same reference numerals are given to the same members and parts as those in the above-described embodiment, and the description thereof will be omitted.

  14 to 17 show a door frame adjusting tool 30E according to an embodiment in which ribs are provided on the seat plate member. The door frame adjustment tool 30E includes a seat plate member 31E fixed to the vertical frame member 11, a plate spring 32E fixed to the seat plate member 31E, and the seat plate member 31E via a plate spring 32E. 16 and an adjustment screw 33 to be fixed to the motor 16. In addition, although the leaf | plate spring 32E in this door frame adjustment tool 30E is shown as a trapezoidal thing approximated to the leaf | plate spring 32A of embodiment shown in FIG. 9, it is not limited to this, For example, FIG. A wave-like leaf spring as shown in FIG.

  The seat plate member 31E is substantially the same as that of the above-described embodiment. Is different in that. The ribs 45, 45 are formed in a direction extending substantially in the front-rear direction (long side direction of the seat plate member 31E) in a state where the seat plate member 31E is attached to the vertical frame member 11. The height h1 of the ribs 45, 45 is preferably set corresponding to the spring strength of the plate spring 32E. For example, when a steel plate having a plate thickness t1 = 1.8 mm is used as the seat plate member 31E, h1 = It is preferable to be about 3 mm. The plate spring 32E has a plate thickness t2 of about 0.5 mm, and a screw insertion hole 43 through which the adjustment screw 33 is inserted is formed at the center. In this embodiment, the screw insertion hole 43 has a substantially rectangular shape. . Similarly to the above-described embodiment, a cylindrical protrusion 36 that protrudes from the center of the seat plate member 31E toward the vertical frame member 11 is integrally formed, and a screw insertion hole 37 through which the adjustment screw 33 is inserted. Is formed.

  The pin-like protrusions 38, 38 near the upper and lower ends of the seat plate member 31E are assembled so as to penetrate the long holes 40, 40 near the upper and lower ends of the leaf spring 32E, and serve as a guide when the leaf spring 32E is pressed and deformed. work. As shown in FIG. 17, the seat plate member 31E is fixed to the vertical frame member 11 by screws 34, 34 inserted through screw holes 38a, 38a in the pin-shaped protrusions 38, 38. When screwed into the frame member 11, the lower surface of the screw head is in contact with the upper ends of the pin-like protrusions 38, 38, and cannot be closer to the vertical frame member 11 side, and is substantially non-contact with the leaf spring 32E. Is maintained. Accordingly, the leaf spring 32E can be deformed relatively freely without being restricted by the screws 34, 34, only by loosely fitting the pin-like protrusions 38, 38 in the long holes 40, 40. . When the leaf spring 32E is deformed, the pin-like projections 38 and 38 are relatively moved in the long holes 40 and 40 to allow a positional deviation.

  Since the configuration, shape, dimensions, and the like of each member other than those described above are the same as those in the above-described embodiment, description thereof will be omitted. In addition, the method for attaching the door frame 10 to the opening of the wall 23 using the door frame adjuster 30E and the procedure for adjusting the door frame position in the front / rear / left / right / up / down directions are the same as in the previous embodiment. Description is omitted.

  When the seat plate member 31E is fixed to the vertical frame member 11 and the leaf spring 32E is elastically deformed and pressed against the housing 16, the seat plate member 31E receives a reaction force from the leaf spring 32E, and this reaction force is elastic. In order to act intensively on the upper and lower end portions of the seat plate member to which the member is attached, the seat plate member tries to bend in a convex shape toward the housing, but is fixed to the vertical frame member 11 on the seat plate member 31E. In this state, the pair of ribs 45, 45 extending substantially in the vertical direction are provided, so that the occurrence of the convex warpage is effectively prevented. Therefore, the space | interval of the housing 16 and the vertical frame member 11 is fully ensured, and space | interval adjustment can be performed in the state which ensured the adjustment allowance sufficiently. Furthermore, since the seat plate member 31E is not warped or bent, it is possible to perform efficient position adjustment while maintaining the vertical frame member 11 at a predetermined position.
