A vibration isolating member 13 formed in a substantially bottomed cylindrical shape.
is attached. The cover 12 and the vibration isolating member 13 have screws 14 inserted into through holes 132 and 122 formed in the center of the bottom 131 of the vibration isolating member 13 and the center of the cover 12, respectively. It is attached to the record player housing 11 by being screwed into a screw hole 112 formed in the lower surface 111 of the housing 11. Further, a coil-shaped spring 15 is inserted through the vibration isolating member 13, and one end of the spring 15 is brought into contact with the cover 12, and the other end is attached to the vibration isolating member 13.
It abuts on a locking part 133 formed so as to be folded back to the outside at the open end of.

２４が取着されている。Here, the open end of the vibration isolating member 13 is fixed to the top plate 17 of the substantially box-shaped leg portion 16 with, for example, adhesive. A transformer 18 is mounted within the leg portion 16, and one end of each of lead wires 19 and 20 is connected to a connecting electrode (not shown) of the transformer 18. The other ends of the lead wires 19 and 20 are connected to a predetermined circuit (not shown) inside the record player housing 11 by passing through a through hole 211 formed in the side plate 21 of the leg portion 16. . Further, the bottom plate 22 of the leg portion 16 includes legs 23,
24 is attached.

ることができるものである。At this time, vibrations caused by the drive of the transformer 18 are transmitted to the vibration isolating member 13 via the legs 16, but are absorbed by the interaction between the elastic force of the vibration isolating member 13 and the spring 15. This prevents the signal from being transmitted to the player housing 11. Therefore, according to the configuration as in the above embodiment,
Without providing the transformer 18 inside the record player housing 11,
Since it is attached to the leg portion 16 connected to the record player housing 11 via the vibration isolating means (insulator) consisting of the vibration isolating member 13 and the spring 15, a sufficient vibration isolating effect can be obtained. In turn, it is possible to improve the acoustic characteristics.
