PROBLEM TO BE SOLVED: To provide a curve correction rail bender for reducing a storage space, improving working efficiency without requiring time for carrying and installation work, and installable without removing a rail from a sleeper even when pressing the rail and a joint plate.SOLUTION: A curve correction rail bender comprises a rail bender body 11 having a pressing force generating mechanism part 11a and provided with a first connection pin insertion hole 11b for inserting a first connection pin 14a into its both sides and a pair of joint blocks 12 respectively installed on both sides of the rail bender body 11, provided with a pin insertion hole 12d for respectively inserting a first connection pin 14a into a base end part and supporting a rail from the opposite side of a pressing part 11a3 of the rail bender body 11, and the rail bender body 11 and the respective joint blocks 12 are connected by inserting the first connection pin 14a by adjusting a position between the pin insertion hole 12 on both sides of the rail bender body 11 and the pin insertion hole 12d on the base end side of the respective joint blocks 12. 【課題】保管スペースが小さく、かつ、運搬や設置作業に時間がかからず作業効率が向上すると共に、レールや継目板を押圧する場合でもレールをマクラギから取外さずに装着できる曲線整正レールベンダーを提供すること。【解決手段】押圧力発生機構部１１ａを有すると共に、その両側に第１連結ピン１４ａが挿入される第１連結ピン挿入孔１１ｂが設けられたレールベンダー本体１１と、レールベンダー本体１１両側にそれぞれ取付けられ基端部にはそれぞれ第１連結ピン１４ａが挿入されるピン挿入孔１２ｄが設けられ、レールベンダー本体１１の押圧部１１ａ３とは反対側からレールを支持する一対のジョイントブロック１２とを備え、レールベンダー本体１１両側のピン挿入孔１２と各ジョイントブロック１２の基端側のピン挿入孔１２ｄとの位置を合わせ、第１連結ピン１４ａを挿入することによりレールベンダー本体１１と各ジョイントブロック１２とを連結する。【選択図】図１
