ABSTRACT:
A hermetically-sealed handle assembly is disclosed. The assembly cuts labor costs and improves the productivity in manufacturing. A back plate 1 has a hole 4 in its central portion, in which 4 a head 3 of a pivot bolt 2 is inserted in a non-rotatable manner. A base plate 5 has a through-hole 7 for receiving therein a threaded shaft 6 of the bolt 2, and is provided with a hole 8 having its hole edge 8a subjected to a burring operation through which the hole edge 8a is passed through a through-hole 24 of the back plate 1 and turned outward behind the plate 1 to have it fixed to the base plate 5. A handle 9 has an axial hole 10 for receiving the threaded shaft 6 therein. A cap nut 11 is threadably engaged with a front end of the bolt 2 through a washer 12. A screw 14 threadably engages with a radial hole 13 of the nut 11, the screw 14 having its front end intensely abutted against a side surface of the threaded shaft 6.
