摘要： A joint structure and a wind regulator having high separation strength, A lift arm (5) is provided with: a tapered through-hole (35) which has formed thereon a first inner wall section (33) work-hardened by plastic deformation; and a raised section (45) which has an inner wall surface (41) interconnected with an inner wall surface (31) of the tapered through-hole (35) and which has formed thereon a second inner wall section (43) work-hardened by plastic deformation. A protrusion (1) is formed on a driven gear (3). The protrusion (1) is fitted from the tapered through-hole (35) up to the raised section (45), has an outer wall section (53) work-hardened by plastic deformation, and has an outer wall surface (35) in close contact with the inner wall surface (31) of the tapered through-hole (35) and with at least a part of the inner wall surface (41) of the raised section (45),
