Abstract
Between a nut of a linear-motion converting mechanism that converts rotation of an electric motor into linear motion and a piston is interposed a connecting member that mediates transmission of pressing force between the nut and the piston. The nut is installed to be pivotable with respect to the connecting member, and the connecting member is installed to be radially movable with respect to the piston.
Claims3
An electric braking device including a piston linearly movably accommodated in a cylinder and being configured to generate a braking force according to linear motion of the piston with rotation of an electric motor as power, the electric braking device comprising:
- a linear-motion converting mechanism including a rotary member configured to rotate upon receiving rotation of the electric motor and a linear motion member configured to linearly move according to rotation of the rotary member;
- and
- a connecting member interposed between the linear motion member and the piston to mediate transmission of a pressing force in an axial direction of the cylinder between the linear motion member and the piston;
- wherein
- the linear motion member is installed to be pivotable with respect to the connecting member, and
- the connecting member is installed to be movable in a radial direction of the piston with respect to the piston.
