Hereinafter, the attachment procedure of the upper panel 12 will be described.
First, the attachment device 11 is fixed to the two fixing portions 40 of the upper panel 12 (see FIG. 4). The attachment device 11 is fixed to the upper panel 12 by fastening the first clamping part 23 and the second clamping part 24 through the upper panel 12 with screws 30. Fastening of the 1st clamping part 23 and the 2nd clamping part 24 is performed by screwing the screw | thread 30 in the hole part 35a through the through-hole 35b.

  More specifically, as shown in FIG. 2 (b), the convex portion 31 a is penetrated from the + X axis direction side through the through hole 42 of the upper panel 12 and protruded to the −X axis direction side, and the −X axis direction side The protruding portion 31 a protruding in the direction is fitted into the recessed portion 32 a of the second sandwiching portion 24. Thereby, a gap corresponding to the thickness of the upper panel 12 is formed between the first clamping part 23 and the second clamping part 24, and the upper panel 12 is held in the gap. Then, the screw 30 is inserted from the −X axis direction side through the through hole 35b and screwed into the hole portion 35a of the convex portion 31a. Thereby, the upper panel 12 is clamped between the first clamping unit 23 and the second clamping unit 24.

Next, the attachment device 11 fixed to the upper panel 12 is temporarily held on the rail portion 10. FIG. 5 is a partially enlarged view showing a procedure for temporarily holding the attachment device 11 on the rail portion 10.
As shown in FIG. 5 (a), the upper protrusion 26a of the second hook portion 26 in the attachment device 11 is inserted from the first groove 22a into the second groove 22b, and the lower end of the lower protrusion 26b is positioned below. The end portion on the + Z-axis direction side of the upper protrusion portion 26a is inserted into the + Z-axis direction side of the second groove portion 22b until it is separated from the flange portion 21d. At this time, since the support portion 27 includes a notch formed by the inclined surface 27d, the support portion 27 does not contact the rail portion 10.
Then, with the end on the + Z-axis direction side of the upper protrusion 26a as a fulcrum, the attachment device 11 is rotated counterclockwise as viewed from the + Y-axis direction side around the axis parallel to the Y-axis, and the lower protrusion 26b is The first groove 22a is inserted into the second groove 22b. After the entire second hook portion 26 is inserted into the second groove portion 22b, the lower end portion of the lower projection portion 26b is moved to the second position until the surface on the −Z-axis direction side of the first hook portion 25 comes into contact with the lower flange portion 21d. Drop into the −Z-axis direction side of the groove 22b.

  Thereby, as shown in FIG.5 (b), the 2nd hook part 26 whole is inserted in the 2nd groove part 22b. At this time, the upper protruding portion 26a engages with the upper flange portion 21c from the −X axis direction side, and the lower protruding portion 26b engages with the lower flange portion 21d from the −X axis direction side. Therefore, the second hook portion 26 is not detached from the second groove portion 22 b and is temporarily held by the rail portion 10.

The auxiliary portion 27c contacts the surface on the + X axis direction side of the lower collar portion 21d.
Due to the weight of the upper panel 12 and the mounting device 11 itself, the mounting device 11 generates a moment about the Y-axis in the counterclockwise direction when viewed from the + Y-axis direction side. On the other hand, a drag force in the −X-axis direction is generated on the contact surface between the upper protrusion portion 26a and the upper collar portion 21c, and a drag force in the + X-axis direction is generated on the contact surface between the auxiliary portion 27c and the lower collar portion 21d. To do. These drags generate a clockwise Y-axis moment as viewed from the + Y-axis direction side, so that the Y-axis moment balances and the mounting device 11 is temporarily held on the rail portion 10.

Thereafter, as shown in FIG. 2, the attachment device 11 is fastened and fixed to the rail portion 10 by the fastening member 28.
Specifically, the fastening member 28 is passed through the second clamping portion 24 via the washer 29 from the + X axis direction side of the first clamping portion 23 via the through hole 34 a and the through hole 41 of the upper panel 12. Screwed into the hole 34b. Then, the fastening member 28 is rotated and screwed into the through hole 34b until the end portion on the −X axis direction side of the fastening member 28 comes into contact with the surface on the + X axis direction side of the side wall portion 21e of the rail portion 10.
Thereby, a part of the clearance gap between the upper collar part 21c and the 1st hook part 25 in the 1st groove part 22a can be block | closed with the fastening member 28. FIG. Thereby, when it is going to move the attachment apparatus 11 to + Z-axis direction, the fastening member 28 will contact | abut to the edge part by the side of the -Z-axis direction of the upper collar part 21c. As a result, it is possible to suppress the attachment device 11 from moving toward the + Z axis direction.

When the fastening member 28 is further rotated in the state where the fastening member 28 is in contact with the side wall portion 21e and is to be screwed to the −X axial direction side, the side wall portion 21e prevents the fastening member 28 from moving relatively. 11 receives a force in the direction of moving in the + X-axis direction. However, since the upper protrusion 26a and the lower protrusion 26b of the attachment device 11 are engaged with the upper flange 21c and the lower flange 21d from the −X-axis direction side, the movement toward the + X-axis direction side is inhibited. The As a result, a fastening force is generated between the upper protruding portion 26a and the upper flange portion 21c, and between the lower protruding portion 26b and the lower flange portion 21d.
Thereby, the rail part 10 and the attachment device 11 can be fastened and fixed, and the upper panel 12 can be fixed to the rail part 10.

According to the mounting structure of the present embodiment described in detail above, even when a plurality (two in this case) of the mounting devices 11 are provided, the operation of rotating the mounting devices 11 around the axis parallel to the Y axis. Thus, the second hook portion 26 can be easily inserted into the second groove portion 22b, and as a result, the upper panel 12 can be easily temporarily held on the rail portion 10 from the + X axis direction side.
Moreover, since the fastening member 28 is used thereafter, the attachment device 11 can be easily fixed to the rail portion 10 without changing the posture of the attachment device 11.

  Therefore, the upper panel 12 can be easily fixed to the rail portion 10 in a state in which the attachment device 11 is previously attached to the two fixing portions 40 provided in the Y-axis direction of the upper panel 12.

  Thereby, since the upper panel 12 can be fixed to the rail part 10 with a simple structure and few members, cost can be held down. Further, the appearance when the upper panel 12 is fixed to the rail portion 10 is also good.

  In the mounting structure of the present embodiment, it is desirable that the mounting posture of the upper panel 12 is the same in the temporary holding state and the fixed state. For example, if the mounting orientation of the upper panel 12 in the temporary holding state is tilted counterclockwise as viewed from the + Y-axis direction side around the axis parallel to the Y-axis direction, compared to the fixed state, This is because the upper panel 12 not only disturbs the installer when fixing the apparatus, but also gives the installer an anxiety that the upper panel 12 will fall.

  Since the upper panel 12 is clamped and fixed to the attachment device 11, the attachment posture of the upper panel 12 is determined by the attachment posture of the attachment device 11. Here, when the mounting posture of the mounting device 11 with respect to the rail portion 10 is inclined counterclockwise as viewed from the + Y-axis direction side around the axis parallel to the Y-axis direction compared to the fixed state, for example, Even if it is slight, the counterclockwise tilt around the axis line parallel to the Y-axis direction of the upper panel 12 as viewed from the + Y-axis direction side becomes larger toward the + Z-axis direction.

On the other hand, according to the mounting structure of this embodiment, the amount of protrusion of the auxiliary portion 27c of the support portion 27 in the −X-axis direction is such that the end surface of the auxiliary portion 27c on the −X-axis direction side and the second hook portion 26. The distance between the lower projection 26b and the surface on the + X-axis direction side is equal to the distance between the surface on the + X-axis direction side of the lower flange 21d and the surface in contact with the lower projection 26b in the second groove 22b. It is. Therefore, in the temporary holding state, the attachment device 11 has the upper projection 26a and the lower projection 26b engaged with the upper collar portion 21c and the lower collar portion 21d, respectively, from the −X axis direction side, and the auxiliary portion 27c is the lower collar. The posture is in contact with the surface on the + X-axis direction side of the portion 21d. This is the same as the attachment posture of the attachment device 11 in the fixed state.
Therefore, since the attachment posture of the upper panel 12 fastened and fixed to the attachment device 11 can be made the same in the temporary holding state and the fixed state, the above problem can be solved.

  The length of the first hook portion 25 in the Z-axis direction is such that the upper protrusion portion 26a of the second hook portion 26 is inserted on the + Z-axis direction side of the second groove portion 22b, and the lower protrusion portion 26b is connected to the lower flange portion 21d. When separated, the surface on the + Z-axis direction side of the first hook portion 25 may be separated from the upper flange portion 21a and shorter than the length of the first groove portion 22a in the Z-axis direction.

  Moreover, in this embodiment, although the upper panel 12 provided with the two fixing | fixed parts 40 was used as a to-be-attached member, the to-be-attached member provided with 1 or 3 or more fixing | fixed parts may be sufficient.

  Further, the attached member is not limited to the upper panel 12 and may be any member.

  Moreover, in this embodiment, although the rail part 10 was attached to the edge part of the + Z-axis direction side of the back panel 13 so that the longitudinal direction may turn into a Y-axis direction, it is not restricted to this. For example, the back panel 13 may be attached to the center in the Z-axis direction.

  Further, the direction in which the rail portion 10 is attached is not limited to the direction in which the longitudinal direction is the Y-axis direction. For example, the direction in which the longitudinal direction is the Z-axis direction may be used.

  Also, the member for attaching the rail portion 10 is not limited to the back panel 13 and may be any member.

  In the present embodiment, the rail portion 10 has a linear shape, but is not limited to this as long as the attached member can be attached by the attachment structure of the present invention.

  Also, a dovetail groove similar to the dovetail groove 22 is provided on the surface of the rail portion 10 on the −X axis direction side. The dovetail groove is disposed so as to be symmetric with respect to the dovetail groove 22 and the YZ plane passing through the center of the back panel 13 in the X-axis direction (see FIG. 2). A member to be attached such as the upper panel 12 may be attached to the dovetail groove.
