Thereby, the position of the height direction with respect to the base part 110 is fixed in the center part of the cover part 120 in the depth direction.

  The reinforcing portion 122 is in contact with the back side of the front panel 112 in a state where the cover portion 120 is in a position to close the opening 111. From the back side of the front panel 112, a support portion 116 is provided to protrude. The support part 116 supports the reinforcing part 122 from below.

  Since the front panel 112 has a thickness in the depth direction, it has a thin rectangular top surface portion 112a. A step is provided between the top surface portion 112 a and the support portion 116, and the support portion 116 is lower than the top surface portion 112 a by the height of the reinforcing portion 122.

  A plurality of insertion holes 117 are provided between the top surface portion 112 a and the support portion 116. Further, a plurality of insertion pieces 127 are provided so as to protrude from the reinforcing portion 122 to the front side. The positions of the insertion piece 127 and the insertion hole 117 correspond to each other, and the insertion piece 127 is inserted into the insertion hole 117 when the cover portion 120 closes the opening 111.

  FIG. 4 is a perspective view showing the appearance of the filter 130. The filter 130 includes a ventilation portion 131, a frame portion 132, reinforcing portions 133, 134, 135, 136, a rotation support portion 137, a pressed portion 138, and a hooking piece 139.

  The ventilation portion 131 is a main configuration of the filter 130 and has a substantially rectangular planar shape, and filters out dust and the like in the air. The frame part 132 holds the edge of the ventilation part 131. The reinforcing portions 133 to 136 increase the rigidity of the frame portion 132 and the ventilation portion 131. The reinforcement portions 133 to 136 are provided continuously from the frame portion 132 around the frame portion 132, and with respect to the plane formed by the frame portion 132 and the ventilation portion 131. And bent in a substantially orthogonal direction.

  The rotation support portion 137 functions as a fulcrum of rotation of the filter 130 by being supported by a support portion 118 (see FIG. 2) provided on the back side of the front panel 112. The hooking piece 139 is held by a holding portion 119 (see FIG. 2) provided on the back side of the front panel 112, thereby determining the position of the lower portion of the filter 130.

  The pressed portion 138 is pressed forward (first direction, described later) and downward (second direction, described later) by the front end of the insertion piece 127 that has passed through the insertion hole 117. FIG. 5 is a perspective view showing the pressed portion 138 in an enlarged manner.

  The pressed portion 138 has a height reference portion 138a, a guide portion 138b, a depth reference portion 138c, and a hole 138d. The height reference portion 138a is a flat portion protruding from the reinforcing portion 133 at the same height toward the rear. The guide portion 138b is a portion of an inclined surface that extends rearward and obliquely downward from the height reference portion 138a.

  The depth reference portion 138 c is an example of a receiving portion that receives a force in the first direction from the cover portion 120 in a state where the cover portion 120 closes the opening 111 of the base portion 110. Here, the first direction is the thickness direction of the plate-like portion surrounding the ventilation portion 113 in the front panel 112, that is, the Y-axis direction (the depth direction, the front-rear direction). The depth reference portion 138 c is pressed forward by the front end of the reinforcing portion 122.

  The hole 138d is formed when the depth reference portion 138c is raised by bending. The holes 138d increase the elastic bendability of the height reference portion 138a.

  The positional relationship of the front panel 112, the cover part 120, and the to-be-pressed part 138 in the state which exists in the position in which the cover part 120 closes the opening part 111 is shown in FIGS. FIG. 6 is a perspective view of the front panel 112, the cover portion 120, and the pressed portion 138, showing the height reference portion 138a cut along a plane along the YZ plane. FIG. 7 is a perspective view of the front panel 112, the cover portion 120, and the pressed portion 138, with the depth reference portion 138c cut along a plane along the YZ plane. FIG. 8 is a cross-sectional view of the front panel 112, the cover portion 120, and the pressed portion 138.

  The relative movement between the insertion piece 127 and the pressed portion 138 from the state where the cover portion 120 opens the opening portion 111 to the closing position is divided into steps and described as follows. First, when the cover portion 120 is slid to close the opening 111, the insertion piece 127 enters the insertion hole 117 (first step). When the movement of the cover part 120 further proceeds, the front end of the insertion piece 127 touches the guide part 138b (second step). When the movement of the cover portion 120 further progresses, the front end of the insertion piece 127 moves along the inclined surface of the guide portion 138b (third step) and rides on the height reference portion 138a (fourth step). When the cover part 120 is further moved, the front end of the insertion piece 127 reaches the depth reference part 138c (fifth step).

  In the third step, the filter 130 is pressed by the cover portion 120 via the insertion piece 127 and the pressed portion 138, and moves downward (an example of the second direction). At this time, the moving direction of the cover part 120 is a direction from the rear to the front. However, by receiving the force received by the inclined surface of the guide part 138b, a part of the force can be applied downward.

  In the fifth step, the filter 130 is pressed against the back side of the front panel 112. Further, the filter 130 is moved downward by a predetermined distance along the surface direction of the front panel 112 as compared with the height before receiving the pressure by the cover portion 120. Thereby, the hook piece 139 is held by the holding portion 119 on the back side of the front panel 112.

  FIG. 9 is a perspective view showing the holding portion 119 and the hooking piece 139 in an enlarged manner. The holding part 119 is a plate-like member arranged along the YZ plane, and has a groove 119a that opens upward. The width of the groove 119a (here, the dimension in the Y-axis direction) is substantially equal to the thickness of the hook piece 139.

  The hook piece 139 is a plate-like member bent outward from the reinforcing portion 134 along the surface direction of the filter 130, and the lower end portion 139a enters the groove 119a in the fifth step described above. Thereby, the lower part of the filter 130 is held immovable in the thickness direction (Y-axis direction). The hooking piece 139 has a knob portion 139b for use as a hook when removing the hooking piece 139 from the groove 119a.

  According to the present embodiment having such a configuration, even if the filter 130 is not screwed, the pivot support portion 137 is supported by the support portion 118 and the cover portion 120 is closed, whereby the filter 130 is in a predetermined position. Pressed and fixed. Therefore, since the filter 130 can be easily attached and detached, the complexity at the time of maintenance can be reduced.

  Further, according to the present embodiment, the cover unit 120 moves the filter 130 in the thickness direction (first direction, Y-axis direction) of the front panel 112, so that the filter 130 is in close contact with the back side of the front panel 112. Can do. For this reason, it is difficult to form a gap around the filter 130, so that the dustproof effect by the filter 130 can be sufficiently exhibited.

  Further, according to the present embodiment, the cover unit 120 moves the filter 130 in a direction along the surface of the front panel 112 (an example of the second direction, downward), and the holding unit 119 holds the filter 130 after the movement. Since the filter 130 is held, the filter 130 is also fixed in position by the holder 119 and is unlikely to be displaced.

  Further, according to the present embodiment, the filter 130 receives the pressing of the cover part 120 by the inclined surface of the guide part 138b, so that the front (first direction) and the surface direction (second direction) of the front panel 112 are combined. Can be moved diagonally forward.

  The relative movement between the insertion piece 127 and the first pressed portion 1381 and the second pressed portion 1382 until the cover portion 120 reaches the closing position from the state in which the opening portion 111 is opened is divided into steps. It becomes like this.

  First, when the cover 120 is slid so as to close the opening 111, the insertion piece 127 enters the insertion hole 117 (first step). When the movement of the cover part 120 further proceeds, the front end of the insertion piece 127 touches the guide part 138b (second step). When the movement of the cover portion 120 further proceeds, the front end of the insertion piece 127 moves along the inclined surface of the guide portion 138b (third step) and rides on the height reference portion 138a (fourth step). When the cover part 120 is further moved, the front end of the insertion piece 127 reaches the depth reference part 138c (fifth step).

  In the third step, the filter 130 is pressed by the cover part 120 via the insertion piece 127 and the first pressed part 1381 and moves downward (an example of the second direction). At this time, the moving direction of the cover portion 120 is a direction from the rear to the front, but part of the force can be made to act downward by receiving the force received thereby by the inclined surface of the guide portion 138 b.

  In the fifth step, the filter 130 is pressed against the back side of the front panel 112. Further, the filter 130 is moved downward by a predetermined distance along the surface direction of the front panel 112 as compared with the height before receiving the pressure by the cover portion 120. Thereby, the hook piece 139 is held by the holding portion 119 on the back side of the front panel 112.
