Patent number: 10587085Abstract: Looseness of a rotary connector and lifting of the rotary connector which occurs depending on a harness wiring state are prevented, to reduce inconvenience such as generation of an abnormal sound due to the rotary connector contacting a steering wheel. In a fixing structure of a rotary connector, which includes a projecting piece 15 to fix the rotary connector to a combination switch and a locked portion 22a to be locked by the projecting piece 15 and in which a laterally protruding locking claw 31 is formed in a tip portion of the projecting piece 15, the locking claw 31 of the projecting piece 15 is integrally provided with a flexible urging portion 15a that displaces and urges the locking claw 31 in a locking direction. A contact surface 32 is formed on the locking claw 31, the contact surface 32 obliquely coming into contact with a locking side corner 23 of the locked portion 22a from the opposing side.Type: GrantFiled: April 28, 2017Date of Patent: March 10, 2020Assignees: FURUKAWA ELECTRIC CO., LTD., FURUKAWA AUTOMOTIVE SYSTEMS INC., TOYOTA JIDOSHA KABUSHIKI KAISHA, KABUSHIKI KAISHA TOKAI RIKA DENKI SEISAKUSHOInventors: Shuji Hirai, Kazutaka Kamiya, Toshihiko Kosugi, Shigeo Shigeyama, Nobuyuki Ishigure, Yoshio Chiba, Kunihiko Ikegame, Hideki Matsumura, Tadashi Usuya
