摘要： PROBLEM TO BE SOLVED: To devise a shape structure of a gantry type handle capable of restraining noises by reducing air resistance by a handle as much as possible in either of going and return travel in a rapid transit railway first car with a gantry type handle at a leading roof.
SOLUTION: In this gantry type handle provided at a leading roof of a rapid transit railway first car, legs 1a, 1a are fixed to a leading roof structure with a lateral direction part 1b between the forward and backward legs 1a, 1a held in parallel to the forward and backward direction of the car. A cross sectional shape of the forward and backward legs has an ellipse shape long in the forward and backward direction, and the lateral direction part between the forward and backward legs has a circular cross section. The diameter thereof is equal to a short diameter of the sectional shape of the legs.
