Title:
DRUM BRAKE DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/035626
Kind Code:
A1
Abstract:
The base ends of first and second expansion levers (26, 27) are engaged with a nut (39) so as to allow oscillatory displacement, the nut being screwed onto a screw (38) so as to be capable of displacement in the axial direction. The first expansion lever (26) is engaged with a web (7a) so as to be able to press the web (7a) outward in the radial direction. The second expansion lever (27) is engaged with a strut (25) so as to be able to press the strut (25) outward in the radial direction. By the screw (38) and the web (7a) being engaged via an engagement tube member (56) and a bearing member (57), displacement in the direction of action of the axial component of the reaction force that acts on the screw (38) during braking is restricted.
