Abstract
A bogie frame for a railway vehicle has a pair of side beams made of fiber reinforced plastic material with a box-shaped cross section. A pair of cylindrical horizontal beams span between the paired side beams are formed of a fiber reinforced plastic material. A honeycomb core is filled up in an inner hollow portion of each of the side beams. A reinforcing member is further filled up in the honeycomb core. The coupling comprises a taper pad mounted to end portions of the horizontal beam and the taper sleeve. The taper pad is provided with tapering portions at its ends downwardly tapering from a central portion. The taper sleeve is fitted into a gap between an outer periphery of the tapering portion of the taper pad and an inner periphery of the hole of the side beam.
