Bullbar
（重定向自Roo bar）
A bullbar or push bumper (also roo bar or nudge bar in Australia, moose bumper in Canada, and push bar, bull bar, or grill guard in the United States) is a device fitted to the front of a vehicle to protect its front from collisions, whether an accidental collision with a large animal in rural roads, or an intentional collision with another vehicle in police usage. They vary considerably in size and form, and are usually made of welded steel or aluminium tubing, or, more recently, moulded polycarbonate and polyethylene materials. The "bull" in the name refers to cattle, which in rural areas sometimes roam onto rural roads and highways.
