PURPOSE: To easily view the opposite lane ahead of the road which is blocked by a large vehicle or the like to form a dead angle by providing a mirror for viewing the opposite lane to reflect the opposite lane ahead of the road at the forward right end part in the cabin of a left hand drive car.

CONSTITUTION: In a left hand drive car 10, the view ahead of the car is blocked and a vehicle (oncoming vehicle) 12 traveling on the opposite lane can not be viewed when a preceding large vehicle 11 is present. A mirror 1 capable of reflecting the opposite lane ahead of the road is provided in a tiltable manner at the forward right end part in the cabin of the car, e.g. at the lower end part of a front pillar through a ball-joint, a magnet or the like. This constitution facilitates the viewing of the opposite lane ahead of the road which is blocked by a large vehicle or the like to form a dead angle, and secures the safety in traveling.
