摘要： The floor of a passenger cabin in a railway car is mounted on a base plate 23 of an underframe 11 via plural common joists 33, 34. The vibration of the truck is transmitted via a center pin 27, a bolster 25, center sills, a base plate 23, and common joists 33, 34 to the floor 31, thereby vibrating the floor. Out of the common joists 33 and 34, the common joists 34 that are positioned near the width-direction-center of the car body do not extend beyond the center sill 25 toward the longitudinal end of the car body. This arrangement reduces the vibration of the floor 31 positioned at the longitudinal end portion of the car body.

摘要： The purpose of the present invention is to provide a method that can be easily applied to friction stir welding where the thickness of face plates at one welding portion is different from the thickness of face plates at another welding portion. Three shape members 10, 11, 12 having two butt joint portions are mounted on a jig 15. The face plate 14 of shape member 10 is thick and the face plate 14 of shape member 12 is thin. The protruded height of projection 18 is greater at portion B where surface plates 14 being welded are thin than the protruded height of projection A where surface plates 14 are thick. The depths for inserting rotary tools to shape members 10, 11, 12 for friction stir welding are the same. Friction stir welding is facilitated since the size and insertion depth of all the rotary tools being applied can be the same.
