摘要： A railcar bogie plate spring of the present invention includes: an upper surface member constituted by fiber reinforced plastic in which reinforced fibers are stacked so as to extend in a longitudinal direction; a lower surface member constituted by fiber reinforced plastic in which reinforced fibers are stacked so as to extend in the longitudinal direction; and a core member arranged between the upper surface member and the lower surface member. The core member is constituted by fiber reinforced plastic in which: reinforced fibers are stacked in a width direction perpendicular to a stack direction of the upper surface member and the lower surface member; and in a side view of the core member, the reinforced fibers are inclined relative to a bending neutral axis so as to intersect with one another.

摘要： A fan shroud is provided for a cooling fan that is partially offset relative to a core portion of a vehicle mounted heat converter. The fan shroud has an arcuate portion that is offset from the core portion. The fan shroud also has an arcuate portion and a connection portion that are not offset from the core portion. The fan shroud has an overlap ratio defined as a ratio of the portion of the fan blades covered by the fan shroud in the cooling fan to the axial depth (front end to rear end) of blades. The overlap ratio at the arcuate portion is set smaller than the overlap ratio at the arcuate portion and the connection portion.
