Method of assembling railcar bogie, measurement jig, and railcar bogie

A measurement jig configured to measure a positional deviation between a plate spring and a bogie frame, the plate spring extending in a car longitudinal direction and being supported by a pair of axle boxes arranged away from each other in the car longitudinal direction, the bogie frame including a side wall covering the plate spring from an outside in a car width direction, the side wall including an opening through which a side surface of the plate spring is exposed,

• the measurement jig comprising:
• a vertical portion extending in a vertical direction along the side surface of the side wall, and
• a horizontal portion extending inward in the car width direction from an upper end of the vertical portion, wherein
• the horizontal portion includes:
• a contact surface configured to be brought into surface contact with the side surface of the plate spring in a state that a normal line of the contact surface extends inward in the car longitudinal direction, and
• a mount surface configured to be mounted on a flat portion of a peripheral surface defining the opening of the bogie frame;
• and
• the vertical portion includes a measurement surface that is a vertical surface having a normal line extending in the car longitudinal direction, the measurement surface being configured to form an angle with the side surface of the side wall.
