摘要： An improved method of manufacturing a strut member for use in a strut device of the drum brake, having two strut members and a connecting member provided with a threaded portion for linking both, to function as an adjustor of the shoe clearance. This manufacturing method comprises as least the following two processes: (a) forming a flat plate-like portion partially on a length of a tube while producing a through bore therein as a displaced space, by inserting a mandrel substantially concentrically into a tube material, pressing or squeezing a portion of the tube in the diametrical direction in such a manner that the inside of the tube is pressed onto the mandrel for producing the displaced space therein, after retracting the mandrel until the inside surface of the tube at upper and lower portion thereof on either side of the displaced space closely contact to each other; and (b) forming a cut-out, ranging from the extremity of the tube to a part of the flattened portion, such that the through bore can have the opening thereof at the bottom of the cut-out to be able to engage with the web portion of a brake shoe.

摘要： A parking brake device for a vehicle, including: (a) a backing plate which is fixed to a body of the vehicle such that the backing plate is held substantially perpendicular to an axis of a wheel of the vehicle; (b) first and second arcuate brake shoes which are disposed on one of opposite sides of the backing plate such that the first and second arcuate brake shoes are movable toward and away from each other; (c) a moving mechanism which is positioned between the first and second arcuate brake shoes and which includes a pivotable brake lever, the moving mechanism moving the first and second arcuate brake shoes away from each other when the brake lever is pivoted in a predetermined direction; and (d) an operable member which is connected to the brake lever and which is operable by an operator of the vehicle to pivot the brake lever in the predetermined direction, wherein the brake lever has a connected portion at which the brake lever is connected to the operable member, and wherein the brake lever extends through an aperture which is formed through the backing plate such that the connected portion is positioned on the other of the opposite sides of the backing plate.
