Patent number: RE47671Abstract: A first projection portion projecting outward, in a vehicle width direction, from a front side frame is provided. A front end of the first projection portion is located at the same position, in the vehicle longitudinal direction, as a connection portion of a crash can to the front side frame or located in back of the connection portion. An outward side face of the first projection portion is configured to slant rearward and inward in a plan view. The first projection portion and a power unit are arranged to overlap each other in the vehicle longitudinal direction. Accordingly, an impact transmitted to a vehicle-compartment side in a small overlap collision can be reduced, restraining repair costs of the crash can broken in a low-speed collision as well as maintaining appropriate design flexibility of a vehicle-body front portion.Type: GrantFiled: May 11, 2017Date of Patent: October 29, 2019Assignee: MAZDA MOTOR CORPORATIONInventors: Satoshi Nakamura, Hiroaki Takeshita, Masanobu Kobashi
