Lubricating performance and durability of a variable capacity compressor are secured. A first communication hole 202 is formed to be close to a penetration bolt 201a at an upstream side in a rotational direction, the penetration bolt 201a is disposed outside a rotation trajectory of a rotating member such as a swash plate in a front housing 101, and a second communication hole is formed to be close to an upper penetration bolt 201b at a downstream side in a rotational direction. The first and second communication holes are formed by penetrating a peripheral wall of the front housing 101, a storage chamber 206 storing oil in refrigerant is arranged outside the front housing 101 by communicating with an inner space of the front housing 101 through the communication holes, and while refrigerant in the storage chamber 206 is returned to the inner space from the second communication hole 203, oil in refrigerant received by contacting an upstream side of a first penetration bolt 201a is stored in the storage chamber 206 from the first communication hole 202, and as a result, as a rotational speed is increased, a storage amount is increased.
