Patent number: 9855983Abstract: A rectifier that is installed on a vehicle which includes a front shield at a front of a vehicle compartment, a hood in front of the front shield, a cowl between a back edge of the hood and a lower end of the front shield, and a fender on an outside of the hood and the cowl in a vehicle width direction, the rectifier including a rectifier member that is installed at a region on a side surface of the fender and adjacent to the back edge of the hood, and has a negative pressure generation part which causes an airflow created when the vehicle travels to generate a negative pressure backward. The front shield is shaped like a curved surface that projects toward a front of the vehicle. At least a part of the negative pressure generation part is disposed in front of a shield extension virtual curve.Type: GrantFiled: September 29, 2016Date of Patent: January 2, 2018Assignee: SUBARU CORPORATIONInventors: Yusaku Dogahira, Naoto Watanabe, Hiroshi Niitsu, Kento Ota, Hisafumi Nakaura, Hiroshi Natsui

Patent number: 9714535Abstract: A vehicle such as an automobile includes: a vehicle body having an opening; an opening-closing member that closes the opening; a drive member that drives the opening-closing member so as to open and/or close the opening; a controller that controls the drive member to control the opening-closing member between a fully open position and a fully closed position; and an elastic member provided at a mating portion of the closed opening-closing member and the vehicle body and inserted between the closed opening-closing member and the vehicle body. The controller controls the drive member in a stopping state of the vehicle and opens the opening-closing member from the fully closed position so as to reduce a pressure acting upon the elastic member.Type: GrantFiled: February 11, 2015Date of Patent: July 25, 2017Assignee: SUBARU CORPORATIONInventors: Hiroshi Natsui, Isao Itoi, Hiroyuki Kobayashi, Noriyasu Tanaka, Tetsuro Takahashi, Hiroaki Fujino, Naoto Watanabe
