摘要： A step device includes: a plurality of steps arranged so as to be lined up in a railcar width direction and constituting a part of a floor surface; and drive mechanisms configured to cause the steps to move upward and downward at a railcar-width-direction inner side between an upper position at which the plurality of steps become a part of the floor surface and a lower position at which the steps are moved downward to constitute boarding stairs. Each of the drive mechanisms includes a rotating link configured to rotate about one end portion thereof in a vertical plane, connecting links respectively connecting the rotating link to the steps, and an actuator configured to cause the rotating link to rotate. The steps move upward and downward by the rotation of the rotating links via the connecting links.

摘要： A friction stir welding apparatus includes: a rotating shaft, on which a thread for friction stirring is formed; and a drive unit rotatably supporting the rotating shaft. A rotating shoulder configured to rotate together with the rotating shaft to generate frictional heat between the rotating shoulder and back surfaces of workpieces is fixed to a distal end of the rotating shaft. The rotating shoulder is pushed against the back surfaces of the workpieces by a pushing mechanism. A stationary shoulder penetrated by the rotating shaft and configured to hold the workpieces in a sandwiching manner together with the rotating shoulder is non-rotatably mounted to the drive unit or a member connected to the drive unit.

摘要： A side entrance includes a step, a door frame, a door leaf, and a door pocket. A vertical frame included in the door frame and located close to a bogie includes: an upper vertical frame portion located above a floor surface; and a lower vertical frame portion located under the floor surface. The lower vertical frame portion is located closer to an inner side of the door frame than the upper vertical frame portion. A width of an upper step portion of the step in a car longitudinal direction is larger than a width of a lower step portion of the step in the car longitudinal direction.
