PROBLEM TO BE SOLVED: To reduce the number of caulked portions of a latch assembly and thus shorten assembling time.SOLUTION: A latch assembly includes: a central latch body 15; a cover plate 16 on the surface side; a back plate 17 on the back side; a latch 19 supported by a latch shaft 20; and a ratchet 42 for holding the latch 19 at a full-latching position. The latch shaft 20 includes: an annular flange 21 located at one end on the surface side and abutting on the surface of the cover plate 16; an engagement processing portion 22 located immediately near the back surface side of the annular flange 21, having a diameter slightly larger than that of a cover side latch shaft hole 23 of the cover plate 16 and press-fitted to the cover side latch shaft hole 23; and a caulking projection 26 located at the other end on the back side and inserted into a back side latch shaft hole 30 of the back plate 17. The caulking projection 26 is fixed to the back plate 17 by caulking.SELECTED DRAWING: Figure 7
