Abstract
A scroll compressor includes a movable scroll having first key grooves, a stationary member having second key grooves, and an Oldham coupling provided between the movable scroll and the stationary member. The Oldham coupling is movable with respect to the stationary member along a first axis direction, and with respect to the movable scroll along a second axis direction. The second axis is orthogonal to the first axis and passes through a center of gravity of the Oldham coupling. The Oldham coupling has an annular body portion, at least two first key portions fitted into the first key grooves, and second key portions fitted into the second key grooves. Key gaps are formed between outer peripheral surfaces of the first key portions and inner peripheral surfaces of the first key grooves. The key gaps have first gaps and second gaps wider than the first gaps.
