Abstract
A coupled structure with high separation strength and a window regulator. A lift arm (5) is provided with a tapered through-hole (35) provided with a first inner wall portion (33) work-hardened due to plastic deformation and a swell portion (45) having an inner wall surface (41) continuing to an inner wall surface (31) of the tapered through-hole (35) and provided with a second inner wall portion (43) work-hardened due to plastic deformation. A driven gear (3) is provided with a protrusion (51) fit in from the tapered through-hole (35) to the swell portion (45), provided with an outer wall portion (53) work-hardened due to plastic deformation, and having an outer wall surface (55) in close contact with the inner wall surface (31) of the tapered through-hole (35) and at least a part of the inner wall surface (41) of the swell portion (45).
