Abstract
A bumper reinforcement includes a tubular body including a front wall that serves as an impact surface and a rear wall on a vehicle body side, the tubular body extending in a vehicle width direction and having a hollow cross section; and a tow hook attachment structure for allowing a tow hook to be removably attached thereto. The tow hook attachment structure includes a pair of cylindrical protrusions respectively integrally formed with the front and rear walls of the tubular body by shaping parts of the walls, the cylindrical protrusions being disposed at predetermined positions on the front and rear walls in the vehicle width direction so as to face each other and so as to protrude inward into the hollow cross section, and at least one of the pair of protrusions includes a threaded portion for allowing a threaded portion of the tow hook to be screwed thereinto.
