  The sealed container 10 may be either a high-pressure dome type or a low-pressure dome type. The motor 11 has, for example, a rotor and a stator, and a shaft 12 is fixed to the rotor.

  The accumulator 2 has a cylindrical body 20 and is attached to the hermetic container 10 of the compressor 1 via a support base 3 and a band member 4. A pipe 6 is connected to the compression element 13 from the bottom surface of the trunk portion 20. The trunk portion 20 is disposed along the outer peripheral surface of the sealed container 10 so that the axis of the trunk portion 20 is parallel to the axis of the sealed container 10.

  The support 3 is fixed to the outer peripheral surface of the sealed container 10 and supports the accumulator 2. The support base 3 includes a base portion 30, a pair of support portions 31, 31, and a pair of projection portions 32, 32.

  The base portion 30 has a shape along the outer peripheral surface of the sealed container 10 and is fixed along the circumferential direction of the outer peripheral surface of the sealed container 10.

  The pair of support portions 31, 31 extend from both ends of the base portion 30 in the circumferential direction of the sealed container 10 toward the outside in the circumferential direction of the sealed container 10. The pair of support portions 31, 31 supports the body portion 20 of the accumulator 2.

  The pair of protrusions 32 and 32 are, for example, circular in plan view, and are provided at the contact portions of the pair of support portions 31 and 31 with the body portion 20. That is, the body 20 of the accumulator 2 is supported in contact with the two protrusions 32 and 32, and the eigenvalue of the accumulator 2 is stabilized.

  The band member 4 is wound around the trunk portion 20 of the accumulator 2 and attached to the support base 3. One end of the band member 4 is locked to one support portion 31 of the support base 3, and the other end of the band member 4 is fastened to the other support portion 31 of the support base 3 via a fastening member 7 such as a bolt. ing. That is, the trunk portion 20 of the accumulator 2 is fastened by the band member 4.

The vibration isolating member 5 is provided between the one surface 31 a of the support portion 31 and the body portion 20. The vibration isolating member 5 is made of, for example, rubber or elastomer resin. The anti-vibration member 5 is wound around the entire circumference of the body portion 20.

  The width dimension of the vibration isolation member 5 is smaller than the width dimension of the support base 3 and larger than the width dimension of the band member 4. Here, the width dimension refers to a dimension in the axial direction of the body portion 20. For example, the vibration isolation member 5 has a width of 25 mm, the support 3 has a width of 30 mm, and the band member 4 has a width of 18 mm. Moreover, the thickness dimension of the vibration isolating member 5 is substantially the same as the height dimension of the protruding portion 32, for example, 1 mm.
