摘要： PROBLEM TO BE SOLVED: To provide a roof structure which drain water without discomforting a crew and passengers.SOLUTION: Rainwater pooled on a roof structure CB due to rainfall runs down from a center line CL toward a side structure SB. The rainwater flows in a first direction D1 along a first projection part PP1, and is received by a second projection part PP2 intersecting an imaginary extension line EL of the first projection part PP1. Rainwater is repeatedly transferred between the first projection part PP1 and the second projection part PP2, and it is finally drained toward the side structures SB. The rainwater collides with the projection parts PP and flows along the projection part every time it is transferred from one projection part PP to the other projection part PP, thereby reliably reducing flow power of the rainwater. As a result, a large amount of rainwater is prevented from flowing down toward the side structures SB at one time, thereby reliably preventing a large amount of drained water from falling on a crew and passengers. The crew and passengers are prevented from feeling discomfort.
