Exhaust gas recirculation valve and method of producing exhaust gas recirculation valve

A valve shaft (8) and a drive shaft (11) of an EGR valve (1) are butted to each other. Projections (26a, 26b, 27a, 27b) formed on the inner sides of cotter members (24, 25) of a cotter (23) are engaged with grooves (21, 22) respectively formed in the outer peripheral surfaces of ends of the shafts (...

Zusammenfassung:	A valve shaft (8) and a drive shaft (11) of an EGR valve (1) are butted to each other. Projections (26a, 26b, 27a, 27b) formed on the inner sides of cotter members (24, 25) of a cotter (23) are engaged with grooves (21, 22) respectively formed in the outer peripheral surfaces of ends of the shafts (8, 11). Urging force of a spring (28) for applying urging force in the direction in which valve elements (6, 7) close is applied to the cotter (23) via a spring holder (30) to press the projections (26a, 26b, 27a, 27b) to the grooves (21, 22).
