A railcar braking device that is a unit brake comprising: a brake lever having a point of effort in which a force is input and a point of action that produces a braking force in a member subject to braking, the point of effort going through a first displacement and a second displacement in the stated order when a braking force is generated; and a magnification ratio modulator that configures a magnification ratio of a displacement at the point of action relative to the first displacement at the point of effort to be larger than a magnification ratio of a displacement at the point of action relative to the second displacement at the point of effort; a brake cylinder that includes an air brake part and a spring brake part and that independently generates a braking force directed to a purpose of decelerating a car while the car is traveling by means of the air brake part and a braking force for maintaining a parked state of the car being parked by means of the spring brake part, the air brake part using a pressure of air supplied to a first chamber to displace a first piston and inputting a force to the point of effort of the brake lever, and the spring brake part using a biasing force of a parking brake spring generated by releasing a pressure of air supplied to a second chamber to displace a second piston provided coaxially with the first piston and inputting a force to the point of effort of the brake lever; and a shoe head that is coupled to the point of action of the brake lever and is displaced by a force transmitted from the brake lever to press the brake shoe against the member subject to braking, characterized in that the brake lever includes: a first displaceable member displaced in response to the force; and a second displaceable member separate from the first displaceable member and displaced in response to a displacement of the first displaceable member, the first displaceable member is coupled to the brake cylinder, the second displaceable member is coupled to the shoe head, the first displaceable member and the second displaceable member are coupled to each other, the first displaceable member is displaced when a force is input to the first displaceable member from the brake cylinder, the second displaceable member is displaced in response to a displacement of the first displaceable member, and the shoe head is displaced in response to a displacement of the second displaceable member. a brake lever having a point of effort in which a force is input and a point of action that produces a braking force in a member subject to braking, the point of effort going through a first displacement and a second displacement in the stated order when a braking force is generated;
