Abstract
In a scroll type compressor in which a front housing (46) closes an open end of a easing (2) to define a hollow space, a filed scroll member and a movable scroll member are placed in the hollow space. The front housing has a plurality of holes (4d) for inserting therethrough bolts. One of the casing and the filed scroll member has a plurality of threaded hole portions (2d) and a plurality of non-threaded hole portions (2f) extended from extended ends of the threaded hole portions. The threaded hole portions are for engagement with the bolts inserted into the holes of the front housing. The non-threaded hole portions are for receiving end portions of positioning jigs (60) for an alignment of the front housing relative to the casing with a relative angular degree with each other so that at least one pair of the holes of the front housing and the non-threaded hole portions are used for positioning the front housing and the casing.
