  2. Description of the Related Art Conventionally, there is known a slider support mechanism that supports a slider that supports a rotating shaft provided on a front panel so as to open and close a front panel of an on-vehicle acoustic device. An example of such a conventional slider support mechanism will be described with reference to FIG. A guide rail 21 is fixed to a sheet metal chassis 20 shown in the figure.

  The slider 22 is slidably supported by the guide rail 21, and a hole 22a provided in the slider 22 is fitted to a shaft standing on the lower portion of the front panel (not shown). A shaft erected on the upper portion of the front panel is engaged with a vertical groove provided in the chassis 20. When the slider 22 is driven in the left direction in the figure by a drive mechanism (not shown), the front panel tilts to open a recording medium insertion opening that opens to the front surface of the in-vehicle acoustic device.

  Since the slider 22 is supported so as to be movable with respect to the chassis 20, rattling (rattle) noise is generated when the on-vehicle acoustic device vibrates. In order to prevent the occurrence of the rattle noise, the slider 22 is pressed against the guide rail 21 by the roller 24.

  That is, the lever 23 rotatably supported by the shaft 20a standing on the chassis 20 rotatably supports the roller 24 via the shaft 23a, and is urged counterclockwise by the tension coil spring 25 and the roller 24. Is in pressure contact with the slider 22.

  The above-described slider support mechanism has a problem that the number of parts of the support mechanism of the roller 24 is large and the number of assembling steps is increased, resulting in an increase in manufacturing cost. There is also a problem that the slider 22 can be positioned only in the vertical direction.

  In the disk drive device proposed in Japanese Patent Application Laid-Open No. 2002-48207, as described in paragraphs 0059 and 10 and 12, the stacked portions of the rotating levers 31 and 32 are inclined between the upper chassis 1160 and the stopper 1164. It is positioned by biting into the surface. Such a positioning mechanism positions the rotary levers 31 and 32 in the vertical direction, but there is a problem that the position of the lever in the rotational direction cannot be accurately positioned due to an error in the angle of the inclined surface of the stopper 1164.

  Further, as described in paragraph 0082 and FIG. 20 of the same publication, the slide guide shaft 4410 is pressed by the tapered stopper 4011A of the slide guide hole 4010 and positioned by biting. Also in this case, there is a problem that the positioning cannot be accurately performed due to an error in the inclination angle of the tapered stopper 4011A and the shaft diameter of the slide guide shaft 4410.

In the disk changer device proposed in Japanese Patent Application Laid-Open No. 2002-190151, as described in paragraph 0023 and FIG. 11, a roller 62 biased by a roller biasing spring plate 61 includes a disk cartridge 100, 110, 120. To prevent rattle noise. This mechanism for preventing the generation of rattle noise has a problem that the number of parts of the roller support mechanism is large and the number of assembling steps is increased, resulting in an increase in manufacturing cost.
