PURPOSE:To enable an inner collar to be prevente from falling off from a housing, by forming stop parts of a housing to be respectively brought into contact with an opposite surface. CONSTITUTION:A housing material 13, being formed by drawing in a clearance 12a formed between a die 15 and an inner collar 2, is deformed while causing buckling and compression and formed in a cylindrical shape. And the material generates parts to be deformed and inserted as a stop part 10 to a hook part 3 in a cut removal state of the inner collar 2. Accordingly, a clutch housing, inserting said stop part 10 to be brought into contact with both side surfaces 8, 8 and an opposite surface 9 of the hook part 3, prevents the inner collar 2 from falling off from the housing. |
