- the plate spring 2 includes a plate-like fan device side mounting portion 63 attached to the side wall 21 ⁇ / b> R of the fan case 21 and a housing continuously from both ends of the fan device side mounting portion 63 in the Z direction.
- the band-shaped curved portions 64A and 64B each extending toward the bottom surface 4F side of the body 4 and curving in a substantially U shape, and one ends of the strip-shaped curved portions 64A and 64B are continuously provided at both ends in the Z direction, and substantially L
- a housing-side bending portion 65 that curves in a letter shape, and a plate-like housing-side mounting portion 66 that continuously extends from one end of the housing-side bending portion 65 and is attached to the relay member 11 are provided.
- the fan device side mounting portion 63 is fixed to the side wall 21 ⁇ / b> R by a screw similarly to the fan device side mounting portion 23 according to the first embodiment.
- the strip-shaped curved portions 64A and 64B have the same shape, and are formed so as not to contact the housing 4 when the leaf spring 2 supports the fan device 1.
- the length (width) in the Z direction of the belt-shaped curved portions 64A and 64B is the same as that of the belt-shaped curved portions 24A and 24B described in the first embodiment, but this length (width) m is In consideration of the mass and natural frequency of the fan device 1, the natural frequency of the housing 4, the natural frequency of the hard disk drive 6, the mounting space of the leaf spring 2, the manufacturing cost, etc. It can be determined that the phenomenon does not occur as much as possible.
- the housing-side bending portion 65 is continuously formed at the tips of the band-shaped bending portions 64A and 64B, and has the same length (width) in the Z direction as the band-shaped bending portions 64A and 64B.
- the housing-side mounting portion 66 is formed continuously at the tip of each housing-side bending portion 65, and has a length (width) in the Z direction longer than that of the housing-side bending portion 65.
- a housing connection hole (not shown) for fixing the leaf spring 2 to the relay member 11 is formed in the housing side mounting portion 66, and the inserted screw 13 is formed in the relay member 11. It is fixed to the side wall 4 ⁇ / b> R of the housing 4 via the relay member 11 by being screwed into a screw hole (not shown).
- the fan device side mounting portions 63 are respectively fixed to the side walls 21 ⁇ / b> R and 21 ⁇ / b> L, extend to the outside of the fan device 1, and are curved, and the housing side mounting portion 66 is the fan device arrangement of the housing 4. Since it is attached to the side walls 4R and 4L of the housing 4 via the leaf spring 2 attached to the outside of the region, the vibration generated from the fan device 1 during driving can be absorbed by the leaf spring 2. At this time, since the leaf spring 2 has a plurality of inflection points, the vibration transmission path connecting the fan case 21 that is the vibration transmission source and the housing 4 that is the vibration transmission destination can be long. Since the fan case 21 and the housing 4 are not in direct contact (non-contact), it is sufficient that the vibration in all translation directions and the vibration in all shaft rotation directions generated from the fan device 1 are transmitted to the housing 4. Can be suppressed.
- relay members 11 and 12 may not necessarily be provided depending on the distance between the case-side attachment portion 66 and the side walls 4R and 4L of the case 4, or only one of them may be provided.
- FIG. 23 is an enlarged perspective view showing the right side of the fan device and its mounting structure according to Embodiment 11 of the present invention.
- the same members as those described in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.
- the fan device mounting structure according to the eleventh embodiment is different from the fan device mounting structure according to the tenth embodiment in the shape of the leaf spring 2. That is, in the leaf spring 2 according to the eleventh embodiment, as shown in FIG. 23, instead of providing the relay member 11, the shape of the housing side mounting portion 76 is changed to the relay member 11 and the housing side mounting portion according to the tenth embodiment. 66 is formed into an integrated shape.
- the casing-side mounting portion 76 has a shape in which the relay member 12 and the casing-side mounting portion 66 according to the tenth embodiment are integrated. You may form in.
- the present invention is not limited to this, and depending on the shape and type of the fan 22 Instead of mounting the fan 22 on the fan case 21, the fan 22 itself may be attached to the housing 4 by the leaf spring 2.
- the fan device 1 can be attached to a desired position such as the ceiling surface of the housing 4 in addition to the bottom surface 4F and the side walls 4R and 4L of the housing 4.
