A vehicle door edge protecting device

A vehicle door edge protecting device is provided. The door edge protecting device (1) comprises an input unit (2) for detecting an open/close state of a vehicle door, and a cable (4) for transmittinga detected open/close state of the vehicle door to a drive mechanism (32) of a protector (31). The input unit (2) comprises a piston (24) which is movable according to the open/close state of the vehicle door; a first lever (25) which is rotatable with the piston (24) in an linkage manner; a second lever (26) for transmitting the rotation of the first lever (25) to a transmission member; a firstspring (28) connecting the first and second levers (25, 26) so as to be integrally rotated; and a second spring (29) which applies force onto the first and second levers (25, 26) towards an initial position. When the protector (31) is not movable, the first lever (25) is rotatable relative to the second lever (26) against force of the first spring (28). 本发明提供车门边缘保护装置。车门边缘保护装置(1)包括：输入单元(2)其被构成为检测车门的开闭状态；以及线缆(4)，其将被检测到的车门的开闭
