The washer (66) is manufactured with a metallic sheet. The washers are integrated in rotation with each other by slots (66E). The washer (66) is inserted between a guiding washer (34A) and the washer (68). The washer (66) has a washer activation tab (66P) delimited by surfaces contacting with corresponding coiled springs and an annular runout (42) formed by a section of the washer (66).
