The second cover body 42 is integrally formed so as to protrude in the direction of the rotation axis toward the side. The shaft portion 58 has a cross-shaped cross section, and has a predetermined gap S (see FIG. 7A) between the end portion of the shaft portion 58 and the accommodating portion 54. Further, a locking groove 59 (locking portion) for locking the arm 43 b at one end of the spring 43 is formed on the housing portion 54 side of the second cover body 42. In the embodiment, since the shaft portion 58 is located between the projecting shafts 56 of the second cover body 42 and is provided on the rotation axis of the projecting shaft 56, the housing portion 54 can be accommodated in a compact manner. In the embodiment, the hinge of the substrate cover 40 is constituted by the shaft support hole 49 of the first cover body 41 and the projection shaft 56 of the second cover body 42. However, a projection shaft is provided on the first cover body 41 side. A shaft support hole may be provided in the two cover body 42.

  When assembling the substrate cover 40, the coil portion of the spring 43 is contracted and inserted into the shaft portion 58 of the second cover body 42 through the gap S of the storage portion 55, and the coil portion 43 a of the spring 43 is wound around the shaft portion 58. The end portion is supported by the support piece 52 to prevent the shaft portion 58 from coming off, and one arm 43b of the coil 43a portion is locked in the locking groove 59, so that the spring as shown in FIG. 43 is mounted and held on the second cover body 42. Next, the projection cover 56 of the second cover body 42 to which the spring 43 is temporarily attached is pivotally supported in the shaft support hole 49 while the shaft support piece 50 of the first cover body 41 is bent, and the second cover body 42 is attached. . At this time, by inserting and locking the other arm 43 c of the coil portion 43 a of the spring 43 into the locking hole 51 of the first cover body 41, the second cover body 42 is closed by urging the spring 43 around the axis. It is attached in a state of being biased in the direction. At this time, the open side of the second cover body 42 is held in a closed state by the bias of the spring 43 in a free state. Thus, since the spring 43 can be easily assembled and held in advance on the second cover body 42, the workability of assembling the substrate cover 40 can be improved. In addition, the second cover body 42 can be removed simply by removing the projection shaft 56 from the shaft support hole 49, and the linkage between the spring 43 and the second cover body 42 is released, and the spring 43 is mounted and held on the second cover body 42. Can be easily removed in the state.

  Further, the board cover 40 assembled in this manner rotates the second cover body 42 in the opening direction so that the contact portion 57 contacts the front wall 41a of the first cover body 41, and further rotates, the contact portion 57 pushes (bends) the front wall 41a and rotates to move from the axis O toward the open side of the second cover body 42, thereby locking the second cover body 42 in contact with the first cover body 41. The connector 46b can be held in the exposed state. Therefore, since the wiring work can be performed with the first cover body 41 opened, the work can be easily performed even in a limited narrow space.

  In order to attach the relay board 32 to the storage space 33 of the inner frame 3, the positioning hole 60 formed in the relay board 32 is matched with the positioning projection 37. Then, the mounting cover 47 of the first cover body 41 is inserted and locked into the locking portion 38 so that the board cover 40 assembled with the second cover body 42 is pressed by the holding piece 44 and the relay boards 32a and 32b are pressed. The relay boards 32 a and 32 b are fixed and protected to the inner frame 3 by screwing to the boss 39. At this time, the connector 46a to which the wiring (wire harness; wiring bundle) 30a from the back side of the inner frame 3 is connected through the notch 41b on the upper wall of the first cover body 41 faces, and from the front frame 8 through the opening 45. A connector 46b for connecting the wiring 30b faces. And the connector of the wiring (wire harness; wiring bundle) 30a from the back side of the inner frame 3 faces the notch 41b on the upper wall and is connected to the connector 46b of the relay boards 32a and 32b.

  Then, the second cover body 42 is opened against the bias of the spring 43. At this time, the rear corner (contact portion 57) of the side wall of the accommodating portion 54 is chamfered in a rounded shape in the direction around the axis, and the distance L1 from the axis of the projection shaft 56 to the contact portion 57 is the second cover body 42. By being set slightly longer than the shortest distance L2 from the axial center of the projecting shaft 56 to the front wall 41a of the first cover body 41 when it is attached to the shaft support piece 50 of the one cover body 41, the second When the cover body 42 is opened, the contact portion 57 of the housing portion 54 comes into contact with the front wall 41a of the first cover body 41 as indicated by a virtual line in FIG. When the second cover body 42 is further opened, the contact portion 57 rotates while bending the front wall 41a of the first cover body 41, and the contact portion 57 passes through the shortest distance portion between the shaft center and the first cover body 41. Then, when it moves to the open side from the axial center of the projection shaft 56 (the state shown in FIG. 8B), the contact portion 57 may be rotated even if the second cover body 42 is rotated in the closing direction by the bias of the spring 43. Comes into contact with the front wall 41a of the first cover body 41, the backward movement of the second cover body 42 is prevented, and the open state is maintained. For this reason, when performing wiring work, it is not necessary to support the second cover body 42 by hand, and the efficiency of wiring work can be promoted. In the embodiment, the contact portion 57 is chamfered into a curved surface, but a polyhedral shape close to a curved surface or a part of the curved surface portion may be a flat portion, and at least a part of the contact portion 57 is a flat portion. Thus, the open state of the second cover body 42 can be held in a stable state by this plane portion. In addition, instead of bending the front wall 41a of the first cover body 41, the shaft support portion side is bent, and the contact portion 57 is moved to the open side from the axis of the projection shaft 56 to open the second cover body 42. You may make it hold | maintain in a state.

  Here, an example of the opening / closing operation of the front frame 8 with respect to the inner frame 3 and the behavior of the wiring 30b will be described. As shown in FIG. 3, in a state where the front frame 8 is opened from the inner frame 3, the wiring 30 b led out from the outlet 34 of the front frame 8 is provided in the storage space 33 of the inner frame 3. It is connected via a substrate cover 40 to relay boards 32a and 32b that are connected to a wiring board (control board or the like) on the back side. At this time, the wiring 30b is connected to the connector 46b so as to go around from the lead-out portion 53 to the shaft support side. In other words, the wiring 30b is connected by the second cover body 42 so that the surplus portion is folded by the biasing of the spring 43 in the closing direction. Accordingly, the wiring 30b is in an extended state when the front frame 8 is open, but the open side of the second cover body 42 is in a free state and is biased in the closing direction by the bias of the spring 43, so that the surplus portion of the wiring 30b is folded. Therefore, even if the front frame 8 is opened with great force, the second cover body 42 is connected so that it can be folded in the opening direction against the bias of the spring 43. The excess wiring 30b is pulled out when it is released vigorously, acting as a buffer member, reducing the load on the wiring 30b due to the opening and closing of the front frame 8, and disconnecting the wiring 30b. -It can prevent removal and improve durability.

  Further, when the wiring 30b is pulled out with the front frame 8 open, the second cover body 42 resists the bias of the spring 43 and the contact resistance between the contact portion 57 and the front wall 41a of the first cover body 41. Then, it is rotated and the open state is maintained. At this time, the opening side of the second cover body 42 is not provided with a locking means, so that it can be easily opened and closed, and can be opened quickly when a problem occurs, for quick response. Then, the wiring 30b is pulled out and removed. In particular, when the connector of the wiring 30b is pulled out from the connector 46b, the relay boards 32a and 32b are pressed by the holding pieces 44, so that the mounting structure of the relay boards 32a and 32b is provided. It is robust and can be pulled out reliably.

  Next, when the front frame 8 is closed to the inner frame 3, the second cover body 42 is pivotally supported on the hinge part 4 side with respect to the first cover body 41 and is urged in the closing direction by the spring 43. Thus, in the opened state, the extended wiring 30b is accommodated so as to be folded to the open side of the inner frame 3 by the second cover body 42, so that it is not sandwiched between the front frame 8 and the inner frame 3. As described above, it is possible to prevent the wiring 30b from being bent and to prevent disconnection.

  The relay boards 32a and 32b may be attached to the first cover body 41 with screws or locking pieces in advance, and the relay boards 32a and 32b can be mounted by attaching the board cover 40 to the inner frame 3. .

  Further, the urging member is not limited to the torsion coil spring, and may be a plate spring 63 having a Ω shape in side view as shown in FIG. Further, the plate spring 63 has a cylindrical portion 63a fitted into the shaft portion 58 and is formed in a cross-sectional C shape with a part of the cutout, and the first cover body 41 and the second cover member in the direction intersecting the axis of the cylindrical portion 63a from the cutout opening. Plate-like arms (linking portions) 63b and 63c linked to the cover bodies 42 are extended. In this embodiment, a locking long hole 51A for locking the arm 63c of the leaf spring 63 is formed on the front wall 41a of the first cover body 41, and the arm 63b of the leaf spring 63 is locked on the second cover body 42. An engaging portion 59A is formed. The plate spring 63 having the above-described configuration is fitted as shown in FIG. 9B with the opening of the cylinder portion 63a facing the shaft portion 58, and the arm 63b is engaged with the locking portion 59A to thereby form the second cover. The leaf spring 63 can be easily attached to the body 42. Then, the board cover 40 inserts and locks the arm 63 c of the leaf spring 63 temporarily attached to the second cover body 42 into the locking long hole 51 </ b> A of the first cover body 41, and the protrusion shaft 56 is locked to the first cover body 41. The second cover body 42 is urged in the closing direction by the urging of the leaf spring 63 about the axis of the first cover body 41 while being pivotally supported by the shaft support hole 49 while bending the shaft support piece 50. It is assembled with.
