<p>[Problem] A situation occurs repeatedly wherein the end plate of the orbiting scroll, when viewed from the direction of the rotational axis, does not constantly cover (disengages from) the outermost circumferential part of the inner wall of the fixed scroll, resulting in abnormal wear and vibration, which reduces the reliability. [Solution] A scroll compressor wherein: the interior of a sealed container (10) is divided into a low-pressure space (13) and a high-pressure space (12) by a partition plate (11); a compression element (14) having a fixed scroll (19) and an orbiting scroll (20), and an electromotive element (15) that rotationally drives the orbiting scroll (20), are provided in the low-pressure space (13); a protruding part (38b), a portion of the end surface of which expands outward, is formed on an end plate (38) of the orbiting scroll; the fixed scroll (19) is equipped with a fixed spiral lap (32) erected on an end plate (31) of the fixed scroll; and when a fixed lap inner wall (32in), which is formed over an interval running 360° from the winding-end part (39b) of the fixed spiral lap (32), is set as the outermost circumferential part (32a) of the inner wall, the outermost circumferential part (32a) of the inner wall is constantly covered by the end surface of the orbiting scroll end plate (38) during rotational driving of the orbiting scroll.</p> |
