     BACKGROUND OF THE INVENTION 
     Field of the Invention 
     The present invention relates to a support jig for assembling an elevator car detachably fixed to a car rail for use when an elevator car is assembled in a shaft. 
     Description of Related Art 
     Conventionally, there is known a car frame support base (a support jig for assembling an elevator car) used by being fixed to a car rail when an elevator car is assembled in a shaft (see JP S56-23913 B). Specifically, as shown in  FIG.  10   , a car-frame support base  100  includes a mounting member  104  configured to be fixed to a car rail  103  by a plurality of clips  101  and a plurality of bolts  102 , a car frame receiving seat  105  formed integrally with the mounting member  104 , a member  107  detachably fixed to the mounting member  104  by bolts  106 , and a car frame receiving seat  108  formed integrally with the member  107 . 
     In the car-frame support base  100 , the mounting member  104  is disposed on the rear surface of the car rail  103  (i.e., on the side opposite to the side along which the elevator car is guided), the clips  101  are disposed on the front surface of the car rail  103  so that the car rail  103  is held between the mounting member  104  and the clips  104 , and the bolts  102  are temporarily fastened to fix the mounting member  104  to the car rail  103 . 
     Subsequent to the fixing of the member  107  to the mounting member  104  by the bolts  106 , the height position and the posture of the car-frame support base  100  with respect to the car rail  103  are adjusted in a state where the bolts  102  attached to the mounting member  104  are temporarily loosened, so that two mounting surfaces (upper surfaces) of the car-frame support tables  105 ,  108  are horizontally held at a certain height position. Thereafter, the bolts  102  are tightly fastened to thereby fix the car-frame support base  100  to the car rail  103 . 
     When the car frame support bases  100  are respectively fixed to a pair of car rails  103 , the car frame  109  is mounted on the car-frame support tables  105 ,  108  of the car frame support bases  100 . Accordingly, the car is assembled in this state. 
     In the adjustment of the height position and the posture of the car-frame support base  100  with respect to the car rail  103  at the time of mounting the car-frame support base  100  to the car rail  103 , it was necessary to move the entire car-frame support base  100 , while the bolts  102  that respectively fix the clips  101  to the mounting member  104  are kept loosened, for the aforementioned adjustment of the height position and the posture. 
     In the car frame support bases  100 , a weight of the elevator car applied to the car frame support bases  100  during the elevator car is assembled is supported by holding the car rail  103  between the mounting member  104  and the plurality of clips  101 . Because of this, the mounting member  104  was demanded to have a sufficient size enabling the plurality of clips  101  (six clips in the example shown in  FIG.  10   ) to be disposed thereon, which causes increase in their weights. Therefore, the mounting operation of the car frame support bases  100  to the car rail  103  in the limited work space in the shaft was difficult to perform.

     A pair of car rails are provided for one car in an elevator shaft. The pair of car rails are disposed on both sides in a width direction of the car in the shaft (i.e., the direction orthogonal to an entrance direction) to guide the ascending and descending car. Specifically, as shown in  FIG.  7    and  FIG.  8   , each of the pair of car rails  10  includes a rail base  11  having a vertically extending bar shape, and a rail web  12  vertically extending and protruding from the central part in the width direction of the rail base  11  toward the car side (that is, the direction orthogonal to each of the width direction and the vertical direction of the rail base  11 ). The rail base  11  is a portion fixed to, for example, a wall surface that defines the shaft, and the rail web  12  is a portion that is held in the thickness direction thereof between rollers of a roller guide provided in the car. In the description hereinafter, a rear surface  11   a  of the rail base  11  (i.e., the surface on the side opposite to a front surface  11   b  from which the rail web  12  protrudes) will be also referred to as the rear surface of the car rail  10 , and the front surface of the car rail  10  (i.e., the surface from on which the rail web  12  protrudes) will be also referred to as the front surface of the car rail  10 . 
     As shown in  FIG.  1    to  FIG.  8   , the support jig  1  includes a first member  2  and a second member  5  that are respectively detachably attached to the car rail  10  and that are separable from each other. The support jig  1  further includes at least one coupling member that couples the first member  2  and the second member  5  to each other.

In the first-member fixing part  31  of this embodiment, two long holes  311  are disposed with a distance from each other in the vertical direction at positions corresponding to the edge on one side in the width direction of the rail base  1 , and one long hole  311  is disposed at a position corresponding to the edge on the other side in the width direction of the rail base  11 . The upper long hole  311  at the position corresponding to the edge on the one side of the rail base  11  is disposed at the same height as the long hole  311  at the position corresponding to the edge on the other side of the rail base  11 . The two long holes  311  at the same height are disposed on the upper side of the connecting part  32 . Specifically, the two long holes  311  are disposed in the rectangular portion (i.e., the upper end portion of the first-member fixing part  31 )  31   b  extending upward from the triangular portion  31   a  in the first-member fixing part  31 . 
     The two through holes  313  are disposed in the upper end portion of the first-member fixing part  31 . Specifically, the two through holes  313  are disposed in the upper end portion (i.e., the rectangular portion)  31   b  of the first-member fixing part  31  respectively at the positions corresponding to the edge on the one side and the edge on the other side in the width direction of the rail base  11 . The two through holes  313  are used as marks for positioning the first member body  3  relative to the rail base in the width direction when the first member body  3  is attached to the rail base  11 . The two through holes  313  of this embodiment are disposed on the upper side of the two long holes  311  in the rectangular portion  31   b . Note that the through holes  313  can have another form (for example, a recess or a projection) as long as they can be used as marks for positioning. 
     The connecting part  32  has at least one long hole  321  extending from the first-member fixing part  31  in the protruding direction and penetrating through the connecting part  32  in the width direction. Specifically, the connecting part  32  extends from the rectangular portion  31   c  of the first-member fixing part  31 . The connecting part  32  is a plate-shaped portion extending in the protruding direction and in the vertical direction. The connecting part  32  of this embodiment is a rectangular portion and has two long holes  321 . 
     The two long holes  321  are disposed with a distance from each other in the vertical direction and extend in the vertical direction. In the connecting part  32  of this embodiment, the two long holes  321  are disposed on a distal end (i.e., an end on the opposite side to the first-member fixing part  31  side in the protruding direction). 
     The plurality of first clamping assemblies  35  are fixed to the first-member fixing part  31  with the car rail  10  (specifically, the rail base  11 ) held between the first-member fixing part  31  and the first clamping assemblies  35  to thereby fix the first-member fixing part  31  to the car rail  10 . The magnitude of the clamping force of each of the first clamping assemblies  35  to clamp the car rail  10  when they are fixed to (disposed on) the first-member fixing part  31  is adjustable. 
     Specifically, the plurality of first clamping assemblies  35  each include a clip  36  that is configured to clamp the car rail  10  (specifically, the rail base  11 ) between the first-member fixing part  31  and the first clamping assembly  35 , a bolt  37  that is inserted into the long hole  311  of the first-member fixing part  31  while passing through the clip  36 , and a nut  38  that comes into threaded engagement with the bolt  37 . The magnitude of the clamping force of each of the first clamping assemblies  35  to clamp the car rail  10  between the first-member fixing part  31  and the first clamping assemblies  35  is adjustable (regulated) by adjusting the tightening force of the bolt  37  applied to the nut  38  (or the tightening force of the nut  38  applied to the bolt  38 ). 
     The clip  36  is a so-called rigid clip and is a plate-shaped member having a through hole  361  through which the bolt  37  is inserted. The clip  36  of this embodiment has a rectangular shape when viewed from the passing direction (i.e., the protruding direction) of the through hole  361 , and is configured to fix the first-member fixing part  31  (specifically, the first member body  3 ) to the car rail  10  by the friction force generated by clamping the end part in the width direction of the rail base  11  between the first-member fixing part  31  and the clip  36  (specifically, the friction force between the clip  36  and the rail base  11 , and the friction force between the rail base  11  and the first-member fixing part  31 ). 
     The mount part  4  has a mounting surface  410  facing upward with the first member  2  fixed (attached) to the car rail  10 . When a car is assembled, a component of the car (a component that forms the car) is mounted on the mounting surface  410  of the mount part  4 . Specifically, the mount part  4  includes a mounting plate  41  having the mounting surface  410 , and a connecting member  42  configured to connect the mounting plate  41  with the first member body  3  and the second member  5 .

     The second member  5  includes a second-member fixing part  51  configured to be detachably fixed to the car rail  10 , a support part  52  extending from the second-member fixing part  51  and configured to support the mount part  4  of the first member  2  from below, and a plurality of second clamping assemblies  53  configured to detachably fix the second-member fixing part  51  to the car rail  10 . In the second member  5  of this embodiment, the second-member fixing part  51  and the support part  52  are formed integrally with each other and formed by bending a plate-like member having a certain shape. The second member  5  of this embodiment has the same size and the same shape (configuration) as those of the first member body  3 . That is, the second-member fixing part  51  of the second member  5  and the first-member fixing part  31  of the first member body  3  have the same size and the same shape. Also, the support part  52  of the second member  5  and the connecting part  32  of the first member body  3  have the same size and the same shape. A detailed description will be given below.

The second-member fixing part  51  of this embodiment is a plate-shaped portion extending along the rear surface  11   a  of the car rail  10  (in other words, a plate-shaped portion extending in the width direction and in the vertical direction) and has three long holes  511  penetrating through the second-member fixing part  51  in the protruding direction. 
     In the second-member fixing part  51 , a second edge  512  located close to the first member  2  (specifically, the first member body  3 ) when viewed from the protruding direction extends in a direction in which the first edge  312  of the first-member fixing part  31  extends, while being in contact with the first edge  312 . That is, the second edge  512  is inclined with respect to the vertical direction. Specifically, the second edge  512  is inclined to extend downward in the width direction of the car rail  10  as it advances from one end on the support part  52  side toward an other end on the opposite side. The second edge  512  of this embodiment extends at an angle of 45° with respect to the vertical direction while being in contact with the entire region or substantially the entire region of the first edge  312  in a direction in which the second edge  512  extends. 
     There is no need for the second edge  512  of the second-member fixing part  51  to be in contact with the entire region of the first edge  312  of the first-member fixing part  31  in the direction in which the second edge  512  extends, and only a partial region of the second edge  512  in the direction in which the second edge  512  extends can be in contact with of the first edge  312  due to, for example, manufacturing errors or mounting conditions to the car rail  10 . Further, a gap can be generated throughout the entire region in the direction in which the second edge  512  extends, between the second edge  512  of the second-member fixing part  51  and the first edge  312  of the first-member fixing part  31  in the entire region in the direction in which the second edge  512  extends. 
     The second-member fixing part  51  of this embodiment has a triangular portion  51   a  including the second edge  512 , a rectangular portion  51   b  extending downward from the triangular portion  51   a  and being elongated in the width direction, and a rectangular portion  51   c  extending from the triangular portion  51   a  and being elongated in the vertical direction (see  FIG.  7   ). 
     The plurality of long holes  511  respectively penetrate through the plate-shaped second-member fixing part  51  in a thickness direction (i.e., the protruding direction) and extend in the width direction within an area including the edge in the width direction of the rail base  11 . In the second-member fixing part  51  of this embodiment, two long holes  511  are disposed with a distance from each other in the vertical direction at positions corresponding to the edge on the other side in the width direction of the rail base  11 , and one long hole  511  is disposed at a position corresponding to the edge on the one side in the width direction of the rail base  11 . The lower long hole  511  at the position corresponding to the edge on the other side of the rail base  11  is disposed at the same height as the long hole  511  at the position corresponding to the edge on the one side of the rail base  11 . The two long holes  511  at the same height are disposed on the lower side of the support part  52 . Specifically, the two long holes  511  are disposed in the rectangular portion (i.e., the lower end portion of the second-member fixing part  51 )  51   b  extending downward from the triangular portion  51   a  in the second-member fixing part  51 . 
     The support part  52  extends from the second-member fixing part  51  in the protruding direction of the rail web  12  and has at least one long hole  521  penetrating through the support part  52  in the width direction. Specifically, the support part  52  extends from the rectangular portion  51   c  of the second-member fixing part  51  in the protruding direction. The support part  52  is a plate-shaped portion extending in the protruding direction and in the vertical direction. The support part  52  of this embodiment is a rectangular portion and has two long holes  521 . 
     The two long holes  521  are disposed at a distance from each other in the vertical direction and extend in the vertical direction. In the support part  52  of this embodiment, the two long holes  521  are disposed on a distal end (i.e., an end on the side opposite to the second-member fixing part  51  side in the protruding direction). 
     The plurality of second clamping assemblies  53  are fixed to the second-member fixing part  51  with the car rail  10  (specifically, the rail base  11 ) held between the second-member fixing part  51  and the second clamping assemblies  53  to thereby fix the second-member fixing part  51  to the car rail  10 . The magnitude of the clamping force of each of the second clamping assemblies  53  to clamp the car rail  10  when they are fixed to (disposed on) the second-member fixing part  51  is adjustable. Each of the plurality of second clamping assemblies  53  of this embodiment has the same configuration as that of each of the first clamping assemblies  35 . 
     Specifically, the plurality of second clamping assemblies  53  each include a clip  56  that is configured to clamp the car rail  10  (specifically, the rail base  11 ) between the second-member fixing part  51  and the second clamping assembly  53 , a bolt  57  that is inserted into the long hole  511  of the second-member fixing part  51  while passing through the clip  56 , and a nut  58  that comes into threaded engagement with the bolt  57 . The magnitude of the clamping force of each of the second clamping assemblies  53  to clamp the car rail  10  between the second-member fixing part  51  and the second clamping assemblies  53  is adjusted (regulated) by adjusting the tightening force of the bolt  57  applied to the nut  58  (or the tightening force of the nut  58  applied to the bolt  58 ). 
     The clip  56  is a so-called rigid clip and is a plate-shaped member having a through hole  561  through which the bolt  57  is inserted. The clip  56  of this embodiment has a rectangular shape when viewed from the passing direction (i.e., the protruding direction) of the through hole  561 , and is configured to fix the second-member fixing part  51  (specifically, the second member  5 ) to the car rail  10  by the friction force generated by clamping the end part in the width direction of the rail base  11  between the second-member fixing part  51  and the clip  56  (specifically, the friction force between the clip  56  and the rail base  11 , and the friction force between the rail base  11  and the second-member fixing part  51 ). 
     The support jig  1  configured as aforementioned is attached to the car rail  10  in the following manner. 
     First, as shown in  FIG.  3    and  FIG.  4   , the first-member fixing part  31  of the first member body  3  is inserted into the gap between the rail base  11  of the car rail  10  and a wall (i.e., a wall surface that defines the shaft) from one side in the width direction. At this time, the position of the first-member fixing part  31  (i.e., the first member body  3 ) with respect to the car rail  10  is adjusted to allow the two long holes  311  on the upper end portion (i.e., the rectangular portion)  31   b  of the first-member fixing part  31  to be respectively disposed at the positions corresponding to the ends in the width direction of the rail base  11 . In this position adjustment, the position of the first member body  3  in the width direction with respect to the rail base  11  is adjusted with the two through holes  313  provided in the upper end portion (i.e., the rectangular portion)  31   b  of the first-member fixing part  31  serving as marks for the positional alignment. 
     After the position adjustment, the first clamping assemblies  35  are respectively attached to the two long holes  311  on the upper end portion (i.e., the rectangular portion)  31   b  of the first-member fixing part  31 . Specifically, each end in the width direction of the rail base  11  is held between the first-member fixing part  31  and the first clamping assembly  35 , and the clip  36  is disposed at a position at which the through hole  361  overlaps with the long hole  311  of the first-member fixing part  31 . In this state, the bolt  37  is inserted into the through hole  361  of the clip  36  and the long hole  311 , and then the nut  38  is attached to the bolt  37  which has been inserted into the through hole  361  and the long hole  311 . At this time, the bolt  37  or the nut  38  is tightened up to prevent the first member body  3  from dropping off from the rail base  11  in each of the first clamping assemblies  35  attached to the first-member fixing part  31 . Thereby, the first member body  3  is temporarily fixed to the car rail  10 . 
     Next, as shown in  FIG.  5    and  FIG.  6   , the mount part  4  (that is, the mounting plate  41  and the connecting member  42  in a coupled state) is attached to the first member body  3 . Specifically, the mounting surface  410  is disposed to face upward, and the downwardly extending part  422  is held in contact with the connecting part  32  from the inside (i.e., the rail web  12  side of the car rail  10 ) to thereby allow the upper long hole  321  of the connecting part  32  in the first member body  3  to overlap with the through hole  422   a  of the downwardly extending part  422  in the mount part  4 . In this state, the bolt B is inserted into the long hole  321  and the through hole  422   a . Then, the nut N is attached to the bolt B that has been inserted into the long hole  321  and the through hole  422   a . Thereby, the mount part  4  is connected to the connecting part  32  of the first member body  3 . 
     At this time, the mount part  4  is connected to the first member body  3  to have the edge  41   b  in the protruding direction of the mounting plate  41  (i.e., the edge opposite to the edge  41   a  defining the recessed part  411 ) coinciding with the distal end in the protruding direction of the connecting part  32 . 
     Next, in a state where the bolts  37  of the first clamping assemblies  35  are loosened, the position and the posture of the first member  2  with respect to the car rail  10  are adjusted to allow the mounting surface  410  in a horizontal state to be disposed at a desired height with respect to the car rail  10  (for example, at a position at which the upper end of a sill of the elevator car to be assembled (i.e., the upper end of a component that defines the lower end of the car entrance) to coincide with the floor level of the bottom floor), and to allow the rail web  12  of the car rail  10  to be located on a virtual line connecting the two marks  410   a  of the mounting surface  410 . After the adjustment, the bolts  37  of the first clamping assemblies  35  are respectively tightened. 
     Subsequently, the first clamping assemblies  35  are attached to the remaining ones of the long holes (i.e., the long holes of the triangular portion  31   a )  311  of the first-member fixing part  31  to thereby fix the first member  2  to the car rail  10 . Note that the first clamping assemblies  35  may not need to be attached to the long holes  311  of the triangular portion  31   a  of the first-member fixing part  31  in the case where the weight of the elevator car to be assembled on the mount part  4  of the support jig  1  is small. 
     Next, as shown in  FIG.  7    and  FIG.  8   , the second-member fixing part  51  of the second member  5  is inserted into the gap between the rail base  11  of the car rail  10  and the wall (i.e., the wall surface that defines the shaft) from the other side in the width direction. At this time, the second-member fixing part  51  is inserted into the gap so that the second edge  512  of the second-member fixing part  51  comes in contact with the first edge  312  of the first-member fixing part  31 , while the downwardly extending part  423  comes into contact with the support part  52  from the inside (i.e., the rail web  12  side of the car rail  10 ) with the upper long hole  521  of the support part  52  in the second member  5  overlapping with the through hole  423   a  of the downwardly extending part  423  in the mount part  4 . In this state, the bolt B is inserted into the long hole  521  and the through hole  423   a  to allow the nut N to be attached to the bolt B that has been inserted into these holes and allow the second clamping assemblies  53  to be respectively attached to the long holes  511  on the lower end portion (i.e., the rectangular portion)  51   b  of the second-member fixing part  51 . 
     Subsequently, the second clamping assemblies  53  are attached to the remaining ones of the long holes (i.e., the long holes of the triangular portion  51   a )  511  of the second-member fixing part  51  to thereby fix the second member  5  to the car rail  10 . Note that the first clamping assemblies  53  may not need to be attached to the long holes  511  of the triangular portion  51   a  of the second-member fixing part  51  in the case where the weight of the elevator car to be assembled on the mount part  4  of the support jig  1  is small. 
     When the support jig  1  is attached (fixed) to each of the pair of car rails  10 , the assembling of the elevator car is performed on the mount parts  4  of these two support jigs  1 . At this time, the fixing long holes  413  of each of the mounting plate  41  of the support jigs  1  are used. Specifically, the assembling of the elevator car is performed while a component of the elevator car is fixed to the mounting plate  41  (the mount part  4 ) by, for example, the bolt B 1  and the nut N 1 . 
     When the assembling of the elevator car is completed, roping is performed and thereafter the support jig  1  is removed from each of the car rails  10 . Subsequently, guide rollers are attached to the portions of the elevator car to which the mounting plates  41  of the support jigs  1  were fixed. Finally, the assembling and installing the elevator car are completed. 
     As in the support jig  1  as aforementioned, when the weight of the elevator car is supported by the two separate members (that is, by the components to be fixed to the car rail  10  while being subjected to a downward force applied to the mount part  4 ), it is possible to achieve downsizing and weight saving of the components (i.e., the first member  2 , the second member  5 ) as compared with the configuration in which the weight of the elevator car is supported by a single member. Moreover, when the configuration is such that the posture and the position in the vertical direction of the mount part  4  can be adjusted by only the one of the two members (i.e., the first member  2  in the example of this embodiment) at the time of fixing this member (i.e., the first member  2 ), it is possible to easily install the support jig  1  to the car rail  10 . 
     Also in the support jig  1  of this embodiment, the first member body  3  includes the first-member fixing part  31  configured to contact the car rail  10  from the rear surface  11   a  side of the car rail  10 , and the plurality of first clamping assemblies  35  configured to fix the first-member fixing part  31  to the car rail  10  by being fixed to the first-member fixing part  31  with the car rail  10  held between the first-member fixing part  31  and the plurality of clamping assemblies  35 . The magnitude of the clamping force of each of the first clamping assemblies  35  to clamp the car rail  10  is adjustable when they are fixed to (disposed on) the first-member fixing part  31 . When the configuration is such that the magnitude of the clamping force of each of the first clamping assemblies  35  to clamp the car rail  10  is adjustable as described above, it is possible to achieve fine adjustment of the posture and the position in the vertical direction of the first member  2  with respect to the car rail  10 , that is, fine adjustment of the posture and the position in the vertical direction of the mount part  4  extending from the first member body  3  in the state where the first member  2  is temporarily fixed to the car rail  10  (i.e., in the state where the first member  2  is prevented from dropping off from the car rail  10 ). 
     Also in the support jig  1  of this embodiment, the first-member fixing part  31  has the plurality of long holes  311  respectively disposed at the positions corresponding to both ends in the width direction of the car rail  10  when the first-member fixing part  31  is held in contact with the car rail  10 , the plurality of long holes  311  being long in the width direction of the car rail  10 . Each of the plurality of first clamping assemblies  35  includes a clip  36  configured to enable the car rail  10  to be held between the first-member fixing part  31  and the clip  36 , a bolt  37  configured to be inserted into the long hole  311  while passing through the clip  36 , and a nut  38  configured to come into threaded engagement with the bolt  37 . Such a simple configuration to allow the nut  38  to come into threaded engagement with the bolt  37  passing through the clip  36  while being inserted through the long hole  311  of the first-member fixing part  31  can make it easy to achieve fine adjustment of the posture and the position in the vertical direction of the first member body  3  with respect to the car rail  10 , while the first member body  3  is temporarily fixed to the car rail  10 . 
     Also in the support jig  1  of this embodiment, the first edge  312  of the first-member fixing part  31  is inclined with respect to the vertical direction, when the first-member fixing part  31  is fixed to the car rail  10  while being in contact with the rear surface  11   a  of the car rail  10 . The second edge  512  of the second-member fixing part  51  extends along the direction in which the first edge  312  extends, and contacts the first edge  312 , when the second-member fixing part  51  is fixed to the car rail  10  while being in contact with the rear surface  11   a  of the car rail  10  (see  FIG.  7   ). Since the first edge  312  and the second edge  512  that are configured to be in contact with each other are inclined with respect to the vertical direction as described above, the downward force (i.e., the weight of the elevator car to be assembled) applied to the first-member fixing part  31  through the mount part  4  is dispersed in a direction in which the first edge  312  and the second edge  512  extend (i.e., the inclined direction) and in a direction orthogonal to the inclined direction (see  FIG.  9   , particularly, arrows F, α, β). Thereby, the first member  2  is less likely to slip down from the position at which the first member  2  is fixed to the car rail  10 . 
     Also in the support jig  1  of this embodiment, the first member body  3  and the mount part  4  of the first member  2  are detachable from each other, and the first member body  3  includes a connecting part  32  configured to connect the first-member fixing part  31  and the mount part  4 . The first member body  3  and the second member body  5  have the same size and the same shape. That is, the first-member fixing part  31  and the second-member fixing part  51  have the same size and the same shape. Further, the connecting part  32  and the support part  52  have the same size and the same shape. The types of the components of the support jig  1  can be thus minimized by configuring the first member body  3  and the second member  5  to have the same size and the same shape as described above. 
     Also in the support jig  1  of this embodiment, the first-member fixing part  31  and the second-member fixing part  51  each have a plate shape extending along the rear surface  11   a , while being brought into contact with the car rail  10  from the rear surface  11   a  side. Therefore, the first-member fixing part  31  and the second-member fixing part  51  can be disposed to be able to be brought into contact with the car rail  10  from the rear surface  11   a  side even in the case where the gap between the car rail  10  and the wall on the rear surface  11   a  side of the car rail  10  (e.g., a wall that defines the shaft) or between the car rail  10  and the component. 
     Also in the support jig  1  of this embodiment, the mount part  4  has a mounting surface  410  facing upward and this mounting surface  410  has a mark  410   a  at a certain position in the width direction. With this configuration, the positional alignment (positioning) of the mount part  4  in the width direction can be made by aligning the mark  410   a  of the mounting surface  410  in the width direction with the position of the rail web  12  of the car rail  10  when viewed from the direction in which the car rail  10  extends. That is, this configuration facilitates the position adjustment of the mounting surface  410  with respect to the car rail  10  in the width direction. 
     The support jig for assembling an elevator car of the present invention is not limited to the aforementioned embodiment, and it is, of course, that various modifications can be made without departing from the gist of the present invention. For example, a configuration of an embodiment may be added to a configuration of another embodiment, and part of a configuration of an embodiment may be replaced by a configuration of another embodiment. Further, part of a configuration of an embodiment may be deleted. 
     In the support jig  1  of this embodiment, the first member body  3  and the second member  5  have the same size and the same shape, but the present invention is not limited to this configuration. The first member body  3  and the second member  5  can respectively have different sizes and different shapes. Also in the support jig  1  of this embodiment, the first-member fixing part  31  and the second-member fixing part  51  are in contact with each other, while the first member  2  and the second member  5  are fixed to the car rail  10  and the second member  5  supports the mount part  4  of the first member  2  from below, but the present invention is not limited to this configuration. It can be configured such that the first-member fixing part  31  and the second-member fixing part  51  are separated from each other, while the first member  2  and the second member  5  are fixed to the car rail  10  and the second member  5  supports the mount part  4  of the first member  2  from below. That is, the first member  2  and the second member  5  can have any configuration as long as the second member  5  supports the mount part  4  of the first member  2  from below, while the first member  2  and the second member  5  are respectively fixed to the car rail  10 . 
     Also in the support jig  1  of this embodiment, the first edge  312  of the first-member fixing part  31  and the second edge  512  of the second-member fixing part  51  are inclined in the same direction with respect to the vertical direction and extend straight, but the present invention is not limited to this configuration. The first edge  312  and the second edge  512  do not need to extend in the same direction, or do not need to be inclined with respect to the vertical direction. Further, the first edge  312  and the second edge  512  do not need to extend straight. That is, the first edge  312  or second edge  512  can be entirely or partly curved. 
     Also in the support jig  1  of this embodiment, the first clamping assembly  35  and the second clamping assembly  53  have the same configuration, but the present invention is not limited to this configuration. The first clamping assembly  35  and the second clamping assembly  53  can have different configurations. 
     Also in the support jig  1  of this embodiment, the first clamping assembly  35  and the second clamping assembly  53  are respectively configured to clamp a part (an end) of the car rail  10  between the clips  36 ,  56  and the first clamping assembly  35  or the second clamping assembly  53 , but the present invention is not limited to this configuration. The first clamping assembly  35  and the second clamping assembly  53  can be configured to, for example, allow the clips  36 ,  56  to clamp a part of the car rail  10  in such a manner as to be able to adjust the magnitude of the clamping force, and to allow the clips  36 ,  56  to be fixed to the first-member fixing part  31  or the second-member fixing part  51 . 
     Also in the support jig  1  of this embodiment, the mounting surface  410  (i.e., the mounting plate  41 ) is formed into a rectangular shape having the recessed part  411 , but the present invention is not limited to this configuration. The mounting surface  410  is not limited to a specific shape. The mounting surface  410  can have any shape as long as it can mount a component of the car thereon when the car is assembled. 
     Also in the support jig  1  of this embodiment, the first member body  3  and the mount part  4  are detachably connected to each other, but the present invention is not limited to this configuration. The first member body  3  and the mount part  4  can be integrally formed. In this case, the mounting surface  410  (i.e., the mounting plate  41 ) has such a shape as to prevent the first-member fixing part  31  from contacting the rail web  12  of the car rail  10  when the first-member fixing part  31  is inserted into the rear surface  11   a  side of the car rail  10 . 
     Also in the support jig  1  of this embodiment, three components are provided to fix the first member body  3  to the car rail  10  (the first clamping assemblies  35  in the example of the aforementioned embodiment), but two components can be provided. Also, four or more components can be provided to fix the second member  5  to the car rail  10  (the second clamping assemblies  53  in the example of the aforementioned embodiment). Minimizing the number of the components to fix the first member  2  to the car rail  10  (the first clamping assemblies  35  in the example of the aforementioned embodiment) can facilitate the adjustment of the position and the posture of the mount part  4  with respect to the car rail  10 . 
     The support jig for assembling the elevator car of the present invention is described above by way of the above embodiments, but is not limited to the aforementioned embodiments. Thus, the support jig for assembling the elevator car according to the present invention can be subjected to various modifications within the intended scope of the present invention. Further, the operation and effect of the present invention are not limited to the above embodiments. That is, the embodiments disclosed herein should be considered to be illustrative in all respects and not restrictive. The scope of the present invention is indicated by the appended claims, not by the above description. It is also contemplated that the scope of the present invention includes all modifications within the meaning and scope of equivalence to the claims
