  • Patent number: 10587085
    Abstract: 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.

  • Patent number: 9487088
    Abstract: An in-vehicle apparatus mounting unit having a projection projecting into a cabin interior includes: a panel provided to face the cabin interior; a support for supporting the projection while the projection is made to project from the panel; and a support case that is attached to the panel on an opposite side to the cabin and accommodates the support in a space formed thereby together with the panel. The support is fixed to the panel or the support case by fixing means, and the fixing means releases the fixation for the support when a load pushing the projection toward the panel exceeds a predetermined load.
