Claims

[Claims for Utility Model Registration] A fixed scroll housed in a housing,
In a scroll compressor that forms a closed space whose volume decreases based on the revolution of the movable scroll between a movable scroll that is provided opposite to the fixed scroll so as to be non-rotatable but rotatable, the spiral portion of the movable scroll is opposite to the spiral portion of the movable scroll. a plurality of truncated cone-shaped recesses are arranged in an annular manner on one side and the fixed member side opposite thereto, and a truncated cone-shaped recess corresponding to each of the recesses is formed between the opposing surfaces of the movable scroll and the fixed member. A scroll compressor in which a bearing element having an engaging portion is interposed such that the engaging portion engages with each recess.
