る。(Effects of the Invention) As described above, in the horizontal scroll fluid machine according to the present invention, the movable scroll (3) is attached to the frame (4) supporting the fixed scroll (2) and the movable scroll (3). An oil receiving portion (8) is formed at the bottom of the frame (4) for accommodating a drive mechanism for orbiting the vehicle and receiving return oil of the lubricating oil supplied to the movable portion of the drive mechanism from the movable portion. , A rotation path of the drive mechanism, which is partitioned between the inner peripheral surface of the casing (1) and the outer wall (4a) of the frame (4) so that oil cannot flow to the oil receiving portion (8). While forming an oil reservoir chamber (9) capable of storing oil at a height higher than the lowest level in the above, the lubricating oil received in the oil receiving portion (8) is forcibly supplied to the oil reservoir chamber (9). Since the pump means (10) for sending is provided, the pump means (10) is As a result, the oil in the oil receiving portion (8) can be forcibly fed to the oil reservoir chamber (9) without accumulating excess oil, and moreover, between the casing (1) and the frame (4). Since the oil reservoir chamber (9) formed by utilizing the space is defined so that the oil cannot flow through the oil receiving portion (8), the oil in the oil reservoir chamber (9) is Since it is possible to store oil at an oil level higher than the lowest level in the rotation locus of the drive mechanism without causing any adverse effect on the drive mechanism, it is possible to reduce the size of the drive mechanism without increasing the overall structure. It is possible to surely secure the oil holding amount necessary for lubricating the movable part in the oil reservoir chamber (9) without any adverse effect due to the oil.
