The clutch 1 basically includes a flywheel 2, a boss 9, a clutch cover assembly 3, and input-output friction members such as clutch disks 42 and 43, an intermediate plate 44, and a pressure plate 17. The boss 9 is detachably coupled to the flywheel 2. The boss 9 includes an annular portion 10 and a plurality of columnar portions 11, which are formed integrally with the annular portion 10. The columnar portions 11 extend in an axial direction from the annular portion 10.
