Title:
ELECTRIC BRAKE DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/037848
Kind Code:
A1
Abstract:
The present invention configures an electric brake device comprising: an electric motor (10); a rotary shaft (23) which rotates about an axis by the electric motor (10); a linear motion member (24) which can move in the axial direction of the rotary shaft (23); a motion converting mechanism (25) which converts rotation of the rotary shaft (23) into axial movement of the linear motion member (24); a friction pad (13) which moves, in the axial direction, together with the linear motion member (24); a rotating mechanism (15) which rotates by the operating force of a driver; and a clutch mechanism (43) which is interposed between the rotary shaft (23) and the rotating mechanism (15) and which cuts off transmission of the operating force from the rotating mechanism (15) to the rotary shaft (23) when the operation amount of the rotating mechanism (15) is less than a predetermined threshold value, and allows transmission of the operating force from the rotating mechanism (15) to the rotary shaft (23) when the operation amount is not less than the threshold value.
