Abstract
A scroll compressor which can be mounted in an automobile has a slide bearing resulting from baking onto a back metal a sliding layer of 5-60 wt % graphite having an average diameter of 5-50 μm and a graphitization degree of at least 0.6, the remainder containing a polyimide resin and/or a polyamide-imide resin. The form of the graphite has: (a) an average shape factor (YAVE) as defined of 1-4 for the particles excluding the minute particles that are no greater than 0.5 times the average diameter, and there being at least 70% by number of particles having a shape factor (Y) in the range of 1-1.5; or (b) graphite particles having a particle ratio of at least 0.5 being at least 50% of the total by number.
