The plate 5 is fitted, and the detection sensor 35 operates the plate detection device to rotate the drive motor 3. Due to this rotation, the turntable 42 is rotated, and since the swing hammers 43, 43 are unbalanced with respect to the fulcrum, the tooth portions having a large thickness are swung toward the outer periphery by centrifugal force. For this reason, the garbage is flipped to the outer peripheral side by the turntable 42 and the swing hammers 43, 43 in the crushing chamber 24 and crushed by the fixed teeth 41, and is crushed between the swing hammers 43, 43 and the fixed teeth 41. Crushed. The crushed garbage falls from the gap between the fixed teeth 41 and the turntable 42 into the discharge chamber 25 and is discharged through the drain pipe 6.

The drive motor 3, the rotation of the turntable 42, the swing of the swing hammers 43, 43, and the crushing of garbage generate noise and vibration. These vibrations are caused by the thin portion 22 b in the middle of the vibration-proof rubber 22. The transmission to the sink S is attenuated. The main body casing 21 is supported by the connection mechanism 15 in a state of being suspended.
Numeral 5 comprises a connecting shaft 16, a connecting member 17, and a spring member 18. Since the spring member 18 can have a small spring constant, the above-mentioned vibration can be greatly attenuated, and the vibration-proof effect is very high. Further, the flange 23, which is a main body side fixing member, is fixed to the ring-shaped protrusion 22a of the vibration isolating rubber 22, and the vibration of the main body casing 21 is directly
3, the vibration-proof effect can be further enhanced.

Although the body-side fixing member attached to the disposer body case side has been shown as an example of a disk-shaped flange, engagement pieces integrally projecting from the body casing are formed at, for example, three places. You may comprise so that a coupling mechanism may be attached to this. Further, the connecting portion between the connecting member 17 and the flange 23 is not limited to the connecting portion 23a protruding from the flange and the connecting portion 17a formed of a through hole in the connecting member. For example, a headed pin is protruded from one side. However, it can be appropriately changed, for example, by providing a receiving portion for receiving the headed pin on the other side.
