Abstract: A collision avoidance assist apparatus executes an emergency steering control including processes to determine a target steering torque used to change a steering angle to avoid a collision of a vehicle with an obstacle so as not to move the vehicle out of a moving lane when the vehicle has a high probability of colliding with the obstacle, and the moving lane is a straight lane, and applies a steering torque corresponding to the determined target steering torque to a steering mechanism. The collision avoidance assist apparatus stops executing the emergency steering control when determining that the moving lane is a curved lane, based on only one of left and right lane markings at an avoidance side of the obstacle which is the left or the right side of the obstacle which the vehicle passes over while executing the emergency steering control.

Abstract: A throttle device includes a default mechanism. The default mechanism includes: a defining portion arranged on the body to define the default position; a first rotation body which rotates integrally with the valve shaft; a second rotation body which can rotate relative to the valve shaft and which engages with the defining portion to limit the rotation in a valve-closing direction; a first urging spring which is interposed between the first rotation body and the body and urges the first rotation body in the valve-closing direction; and a second urging spring which is interposed between the first rotation body and the second rotation body, and urges so as to draw the first rotation body in a valve-opening direction and draw the second rotation body in the valve-closing direction to engage the two with each other and to maintain the engagement during the non-operation of the drive source.

Abstract: Upon arranging a separator tank in a V bank formed between a pair of cylinders, an arrangement position thereof is set to be a position unsusceptible to an influence from an exterior. The separator tank in which a fuel pump that stores liquid fuel in an interior thereof and feeds the liquid fuel toward an injector is accommodated is arranged in the V bank formed between the pair of cylinders which is provided in an engine, and arranged immediately below an air cleaner.
