Abstract: A brake operating device in which an operation of a brake pedal can be detected easily by a simple structure is provided. The brake operating device 1 comprises: a pusher 19, 20 connected to a brake pedal 2; a hydraulic system 5 in which fluid is held between the pusher 19, 20 and a pushing element 27 to transmit a thrust force of the pusher 19, 20 to the pushing element 27; a first elastic mechanism 23a, 23b that establishes an elastic force to isolate the pusher 19, 20 away from the pushing element 27; a cylinder 18 holding the pusher 19, 20 while restricting a withdrawal limit of the pusher 19, 20 in a direction away from the pushing element 27; and a second elastic mechanism 37 that is arranged at a position to push the cylinder 18, and that establishes an elastic force against the elastic force in the direction to isolate the pusher 19, 20 away from the pushing element 27.
