摘要： A railcar axle box suspension includes a coupling mechanism configured to couple an axle box to a bogie frame, and the coupling mechanism includes: an axle beam including a tubular portion; a core rod inserted through the tubular portion, protruding portions being provided at both sides of the core rod; a pair of receiving seats provided at the bogie frame and including fitting grooves, the protruding portions being fitted in the fitting grooves; a pair of lid members supporting the respective protruding portions; fastening mechanisms fixing the lid members to the receiving seats; and locking members. Each of the receiving seats includes a first screw hole. Each of the lid members includes a first insertion hole and a second screw hole. Each of the fastening mechanisms includes: a first bolt; a second bolt; and a plate having a fitting hole and a second insertion hole, the fitting hole being fitted to a head portion of the first bolt and restricting rotation of the first bolt, a shaft portion of the second bolt being inserted through the second insertion hole. The first bolt is threadedly engaged with the first screw hole through the first insertion hole. The fitting hole of the plate is fitted to the head portion of the first bolt, and the second bolt is threadedly engaged with the second screw hole through the second insertion hole. Each of the locking members restricts rotation of the second bolt relative to the second screw hole.
