The display 12 is supported by the shaft portion 74 and is rotatable around the axis of the shaft portion 74.

  That is, since the display 12 is supported by the shaft portion 74 of the display cluster 54 attached to the upper portion of the instrument panel 10, the display 12 can be attached regardless of the duct portion 40. For this reason, deterioration of air-conditioning performance can be suppressed.

  Further, in the present embodiment, since the display 12 can be rotated around the axis of the shaft portion 74, the upper end portion and the lower end portion of the display 12 are not restrained as shown in FIGS. 2 and 8. It is in a free state. That is, the attachment part for attaching the display 12 to the instrument panel 10 side is not provided in the upper end part and the lower end part of the display 12.

  Therefore, although not shown, it is not necessary to secure a mounting space for mounting the mounting portion on the instrument panel 10 in the instrument panel 10. When the center registers 22 and 24 are provided on the lower side of the display 12, if the mounting space is secured, the center registers 22 and 24 are disposed on the lower side of the mounting space. , 24 will be smaller.

  However, in the present invention, since it is not necessary to secure the mounting space in the instrument panel 10, the center registers 22 and 24 can be increased accordingly. Therefore, the air conditioning performance is improved.

  On the other hand, the display 12 may be difficult to see during the day due to sunlight reflection or the like, and often requires an angle adjustment of the display 12 around an axis along the vehicle width direction. In addition, the angle adjustment of the display 12 may be required depending on the height of the passenger's eyes. For this reason, the display 12 can be rotated around the axis of the shaft portion 74 with the vehicle width direction as the axis direction, so that the angle of the display 12 can be easily adjusted according to the position of the sun and the height of the eyes of the passenger. Can be done. Thereby, the visibility of the display 12 can be improved.

  Further, as shown in FIG. 7A, a sliding resistance is obtained between the arc portion 118 of the triangular rib 114 provided on the back surface of the display 12 and the contact portion 90 of the leaf spring 84. Thus, the display 12 can be stopped at a predetermined position around the axis of the shaft portion 74, and the display 12 can be easily rotated manually. For this reason, cost can be reduced compared with the case where the display 12 is rotated by a motor or the like.

The above adverse effect is small. Further, the design can be improved by utilizing the shape of the display cluster 54.

  In the present embodiment, the shaft portion 74 is integrally formed with the display cluster 54 shown in FIG. For this reason, the number of parts can be reduced, and the cost can be reduced. In this case, since it is not necessary to attach the shaft portion 74 to the display cluster 54, the number of work steps can be reduced, and the cost can be further reduced.

  Here, when the shaft portion 74 is integrally formed with the display cluster 54, for example, if the shaft portion is formed in a solid shape (not shown), there is a possibility that sinking occurs on the outer peripheral surface of the shaft portion. Thus, when sink marks occur on the outer peripheral surface of the shaft portion, the dimensional accuracy of the shaft portion is lowered. For this reason, it is better to perform so-called lightening in the shaft portion. Generally, the shaft portion is formed in a cylindrical shape. In this case, a part of the mold is formed along the axial direction of the shaft portion. Need to slide.

  In the present embodiment, as shown in FIG. 4, the hollow portion 75 can be provided in the shaft portion 74 by providing the disc 78 that constitutes the outer periphery of the shaft portion 74 in the circumferential direction of the shaft portion 74. . Thereby, while suppressing the sink of the said shaft part 74, the metal mold | die which shape | molds the display cluster 54 can be manufactured compactly, and the reduction in the cost in metal mold | die expense can be aimed at.

  Further, when the shaft portion 74 is formed integrally with the box-shaped display cluster 54, the bottom wall 54D side of the display cluster 54 in the shaft portion 74 becomes an undercut portion with respect to mold release (not shown). Therefore, in this portion, generally, holes 94 and 96 are provided in the bottom wall 54D of the display cluster 54, and the bottom wall 54D side of the display cluster 54 in the shaft portion 74 is formed through the holes 94 and 96. .

  Here, in the present embodiment, as shown in FIG. 4, an arc wall 92 constituting a part of the outer periphery of the shaft portion 74 in the circumferential direction orthogonal to the axial direction of the shaft portion 74, and the arc wall 92 and a disc 78 constituting the outer periphery of the shaft portion 74 are provided. For example, although not shown, when only the arc wall 92 is formed on the bottom wall 54D side of the display cluster 54, the bottom wall 54D of the display cluster 54 has the shaft portion 74 in order to form the arc wall 92. The holes 94 and 96 are connected in the axial direction. On the other hand, when the disc 78 is formed on the bottom wall 54 </ b> D side of the display cluster 54, the bottom wall 54 </ b> D of the display cluster 54 suffices with the size of the hole for forming the disc 78.

  Therefore, in the present embodiment, on the bottom wall 54D side of the display cluster 54 in the shaft portion 74, a region where the arc wall 92 is provided along the axial direction of the shaft portion 74, and a region where the disk 78 is provided. , The hole provided in the bottom wall 54D of the display cluster 54 is divided compared to the case where only the arc wall 92 is provided on the bottom wall 54D side of the display cluster 54, and the size of the hole is increased. The thickness can be reduced.

  In particular, in the present embodiment, the arc wall 76 hangs down toward the bottom wall 54D of the display cluster 54 on the center side of the shaft portion 74 and is connected to the bottom wall 54D. In this way, the arc wall 76 is connected to the bottom wall 54D, whereby the rigidity and strength of the display cluster 54 can be further improved. That is, according to the present embodiment, the mold mechanism for molding the display cluster 54 can be simplified, and sufficient rigidity and strength to support the display 12 can be obtained.

  In the present embodiment, the peripheral wall 54A of the display cluster 54 is formed with notches 102 and 104 connected to the holes 94 and 96 formed in the bottom wall 54D, and the notches 98 and 100 are formed on the peripheral wall 54B. Are formed respectively. Thereby, when an impact load (arrow F shown in FIG. 2) is input to the display 12, stress can be concentrated on the peripheral portions of the notches 98, 100, 102, and 104. As a result, the display cluster 54 is deformed (elastic / plastic) and can absorb impact energy. For this reason, an impact load can be reduced and the impact which a passenger | crew receives from the display 12 at the time of a vehicle collision can be relieved.

  Further, in the present embodiment, the display cluster 54 is provided with the mounting portion 56, the clip 64 is mounted on the mounting portion 56, and the display cluster 54 is attached to the periphery of the opening 52 </ b> C of the instrument panel 10 via the clip 64. It can be attached. Thereby, an assembly man-hour can be reduced compared with the case where the display cluster 54 is attached to the instrument panel 10 via a bolt.

  In the present embodiment, the shaft portion 74 is integrally formed with the display cluster 54, but the display cluster 54 and the shaft portion 74 may be formed separately. Thereby, different materials can be used for the display cluster 54 and the shaft portion 74.

  Further, here, as shown in FIGS. 3 and 7, a substantially box-shaped display cluster 54 is attached in an opening 52 </ b> C formed in the instrument panel 10, and a shaft portion formed in the display cluster 54. A display 12 is attached to 74. In this state, the display 12 is fitted in the display cluster 54, but the display 12 does not necessarily have to be fitted in the display cluster 54.

  For example, as shown in FIG. 9, the display 12 may be attached to a shaft portion 74 formed in the display cluster 124 in a state of protruding from the opening end of the display cluster 124. Since the shaft portion 74 is the same as the shaft portion 74 formed in the display cluster 54, the same reference numeral is given.

  As an example, here, a plate-shaped display cluster 124 having a substantially L-shaped cross section is used, and a locking claw 126 is provided on the back side of the display cluster 124. The locking claw 126 is locked to the peripheral portion of the locking hole 130 formed on the peripheral edge of the opening 128. Further, the side wall 124 </ b> A of the display cluster 124 may be formed along the shape of the front side 12 </ b> A of the instrument panel 10. In this case, at least in the shaft portion 74, the side wall 124A is formed up to the portion where the arc wall 92 (see FIG. 3) is formed.

  As described above, the shaft portions 74 are provided in the display clusters 54 and 124 so that the display 12 can be attached via the shaft portions 74. However, the display clusters 54 are not necessarily required. For example, although not shown, a shaft portion may be provided along the vehicle width direction so as to span an opening formed in the instrument panel, and the display 12 may be supported by the shaft portion. .

  Although one embodiment of the present invention has been described above, the present invention is not limited to the above, and other various modifications can be made without departing from the spirit of the present invention. It is.
