本考案は電子機器における冷却用フアンの固定

期待できる。 2. Description of the Related Art Conventionally, forced cooling fans have been used when electronic equipment requires cooling.
In this case, unpleasant noise is generated due to the use of a cooling fan, but since the equipment is installed close to the operator, especially in OA equipment, measures are required to prevent noise. The noise from a cooling fan consists of the noise of the fan alone and the vibration caused by the unbalanced rotation of the fan and motor, which causes resonance. When the noise level of the former is high, the discomfort of the latter is less of a concern. However, when the noise level of the former is low, the noise of the latter is highlighted. The latter noise occurs between the fan 1 and the cooling unit 2, between the cooling unit 2 and the case 3, and between the case 3 and the case 3, as shown in Fig. 3.
It occurs between the desk 4 and the desk 4. Even if measures are taken in this case, only a slight effect can be expected, but if measures are taken, a sufficient effect can be expected even without measures.

Two bolts 3 are attached to the main body 30a where 0 is made of rubber or the like.
Since the bolts 0b and 30c are embedded with their bolt heads facing each other, it is necessary to provide a large distance between the bolt heads in order to obtain a sufficient cushioning effect, which results in a large size.
