Abstract: In an electric cylinder device including a third gear that rotates by receiving rotation of an electric motor and a linear motion conversion mechanism that converts the rotation of the third gear into linear motion of a piston inside a cylinder, a nut, which is a linear motion portion of the linear motion conversion mechanism, and the piston are connected in a state in which relative displacement in a radial direction is allowed.

Abstract: An electric braking device generates a braking force at a wheel via application of a pressing force by a piston by linear motion of the piston in response to the transmission of a forward-direction rotational torque from an electric motor to a linear motion conversion mechanism. The electric braking device is provided with a one-way clutch that cuts off the transmission of a rotational torque between the electric motor and the linear motion conversion mechanism when applied with a rotational torque in a direction opposite to the forward direction and having a magnitude equal to or greater than a predetermined value.
