Proposed are a cowcatcher capable of sufficiently absorbing an impact while reducing the weight and cost and a railway vehicle provided with the cowcatcher. In a cowcatcher disposed on a lower surface of an underframe of a railroad vehicle, the cowcatcher includes an impact-absorbing mechanism for absorbing an impact applied to a cowcatcher portion. The impact-absorbing mechanism includes an impact-absorbing portion for absorbing an impact, a pressing portion for pressing the impact-absorbing portion, and a guiding portion for guiding a pressing direction of the pressing portion. The impact-absorbing portion is disposed between the pressing portion and the guiding portion. The pressing portion includes a flange for crushing the impact-absorbing portion and a rod connected to the flange. The guiding portion is a cylinder body into which the rod is inserted, and includes suppression members on upper and lower inner walls of the cylinder body. An end of the rod is guided in an axial direction of the cylinder body while a vertical displacement of the rod is suppressed by the suppression members.
