이 판스프링 장치(1)은, 판스프링 본체(11)와, 제1 눈부(12)와, 제2 눈부(13)와, 연결편(14)을 구비하고, 제1 눈부는, 차체(B1)에, 판스프링 본체의 폭 방향으로 연장되는 제1 축선(O1) 주위에 회전 가능하게 연결되고, 제2 눈부는, 연결편에, 폭 방향으로 연장되는 제2 축선(O2) 주위에 회전 가능하게 연결되고, 판스프링 본체에서의 길이 방향의 중앙부 영역이 차축을 지지하고, 판스프링 본체는, 위쪽을 향하여 휨 변형 가능하게 설치되고, 판스프링 본체가 위쪽을 향하여 휨 변형하는 과정에 있어서, 판스프링 본체에서의 제2 눈부와의 접속 부분(11a)이, 당초에는, 길이 방향으로 변위하는 방향(x1)으로, 접속 부분이, 연결편의 탄성복원력에 의해 가압되고 있다. A leaf spring device (1) includes a leaf spring main body (11), a first eye portion (12), a second eye portion provided (13), and a connection piece (14), the first eye portion is connected to a vehicle body (B1) to be rotatable around a first axis (01) extending in a width direction of the leaf spring main body, the second eye portion is connected to the connection piece to be rotatable around a second axis (O2) extending in the width direction, a central region of the leaf spring main body in the longitudinal direction supports an axle, the leaf spring main body is provided to be flexibly deformable upward, and a connection portion (11a) of the leaf spring main body, at which the leaf spring main body is connected to the second eye portion, is urged by an elastic restoring force of the connection piece in a direction (x 1) in which the connection portion is displaced along the longitudinal direction at an initial stage of a process in which the leaf spring main body is flexibly deformed upward.
