Abstract: A vehicle-mounted radar device providing stabilized performance and enabling a radar main body to be installed easily on a radar bracket. Radar device 100 includes radar main body 106 and a radar bracket 108 for installing on a vehicle. The radar bracket 108 forms an opening area 140 which exposes a transmission and reception surface 112 of the radar main body 106. One or more support parts which are provided on the side plate part 116, and support the radar main body 106 by contacting a side surface 128, or the transmission and reception surface 112 form a withdrawn shape 160 at the end of each of the support parts near the center of the transmission and reception surface 112 and is inclined toward the side distant from the center of the transmission and reception surface 112 and toward the outside of the vehicle.

Abstract: A deviation in rotational angle caused between an adjustment gear and a sensor housing is compensated for with a profile of a cable winding groove of a pulley of an attitude control mechanism to accurately synchronize the inclination angle of a seat back and the rotational angle of the sensor housing with each other. Thus, it is possible to keep an inertial element support surface, which serves as a sensor reference surface, accurately horizontal even at any seat back inclination angle to improve the accuracy of an acceleration sensor.

Abstract: A seatbelt retractor includes a rotation transfer mechanism configured to transfer rotation of an adjustment gear to a sensor housing to swing the sensor housing in the front-back direction of a vehicle. The turning axis of the adjustment gear and the swing axis of the sensor housing intersect each other at a predetermined angle with the swing axis of the sensor housing arranged in a horizontal direction with respect to the left-right direction of the vehicle. An inertial element support surface of the sensor housing is kept horizontal by swing motion of the sensor housing in the front-back direction of the vehicle, even if a seat back is tilted in the front-back direction of the vehicle.
