Certainly in the diameter of throw 5, it is therefore desirable to throw 5 needs have moderate diameter,
Otherwise it is difficult to be appropriately carried out friction stir weld.
In order to process this situation, it is configured to each coupling part 4 is centrally located in border 101
Circumferentially external, to guarantee the width of each coupling part 4 and to reduce the stirring limit of slide component 30
Edge.By this structure, it is possible to reduce the size of slide component 30 further, thus produce tool
There is the compressor housing 1 of lower cost.
Friction stir weld step in order to be easily achieved above-mentioned structure, in aforementioned manufacturing method
In, it is done so as to friction stir weld be pushed in the throw 5 of editing objective
The heart is positioned at the circumferentially external of border 101.This means material (the such as aluminum of enclosure body 20
Alloy) the part of material (such as polyimide resin) of a part and slide component 30
Compare in broader scope, carry out friction stir weld, thus reduce the relative of slide component 30
The cost of expensive material.
