  • Patent number: 10199786
    Abstract: The present invention provides a rotary connector device that enables relative rotation between the rotator and the stator to be easily and reliably fixed at a neutral position even when a steering device is disengaged. A rotary connector device (1) according to the present invention is provided with: a self-rotation pin (50) that is self-rotatable with respect to a sleeve (30) and that is provided with a pin-side notch (521) that restricts the self-rotation by coming into contact with an inner circumferential surface of a stator-side inner-circumferential cylindrical portion (23); a stationary-side gear (231) and a self-rotation-side gear (511) that transmit the relative rotation and the self-rotation in an interlocked manner; and a stationary-side switching mechanism (40) and a pin protrusion (52) that switch, in a neutral position, the self-rotation pin (50) from a released state to a restricted state.

  • Patent number: 9755325
    Abstract: A conductor wire crimping portion (7) has depressions (13a, 13b, 13c) that are disposed at prescribed intervals in the axial direction and that are linear locking portions. The depressions (13a, 13b, 13c) are continuously depressed grooves on the inner surface of a crimping portion (5). On an upper die (30a), at a portion corresponding to the conductor wire crimping portion (7), a straight portion is formed, and in the front-back direction thereof, tapered portions are formed. More specifically, the upper die (30a) is formed to have an inverted trapezoid shape, a middle portion of which protrudes in the crimping direction. Consequently, at each boundary between the straight portion and the tapered portion, a die angled portion (32) is formed. At an area corresponding to the straight portion of the upper die (30a), the depression (13a) is provided, and at an area corresponding to the die angled section (32), the depression (13b) is provided.

  • Patent number: 7980739
    Abstract: An in-vehicle illuminating device 1 capable of efficiently guiding luminous flux emitted from a luminous source to a light guiding body. The in-vehicle illuminating device 1 is provided with a rod-shaped light guiding body 13 which reflects, on its inner surface, light rays incident from an optical incidence plane 16 provided at an end 13a to guide the light rays to the other end longitudinally provided, a lamp 19 which emits light to a direction orthogonal to the longitudinal direction of the rod-shaped light guiding body 13 and is arranged in the vicinity of the optical incidence plane 16, and an light introducing body 20 for introducing the luminous flux emitted from the lamp 19 to the optical incidence plane 16. The light introducing body 20 allows the optical incidence plane 16 to be set within a range of the luminous flux emitted from the lamp 19.

  • Patent number: 7946742
    Abstract: An in-vehicle illuminating device capable of preventing light emitted from a light source from coming directly into a passenger's sight. An in-vehicle illuminating device 1 includes a housing 2, a reflective member 18 provided within the housing 2, a light source or LEDs 10 orienting a light axis of light emitted therefrom to the reflective member 18. Reflected light obtained by allowing the reflective member 18 to reflect the light emitted from the LEDs 40 is irradiated to the outside of the housing 2, thus preventing light emitted from the LEDs 40 from coming directly into a passenger's sight.

  • Patent number: 7938566
    Abstract: There is provided a cover panel including a lighting device which is attachable without a mounting seat. A cover panel 1 includes a panel main body 5 fixed on an instrument panel 3 in an interior of an automobile and a lighting device 6 provided inside the panel main body 5. The panel main body 5 comprises an opening 7 which forms a gap between itself and the instrument panel 3, and light emitted through the opening 7 from the lighting device 6 illuminates the interior of the automobile. The panel main body 5 and the lighting device 6 are integrated and are fixed on the instrument panel 3, so that the cover panel 1 including the lighting device 6 can be fixed on the instrument panel 3 without utilizing the mounting seat as was conventionally done.
