Assembled structure of brake release knob

An assembled structure of a brake release knob in a parking brake in which a brake lever is pivotally movably supported by a base member, the brake lever being pulled up to transmit a force to a braking part through a cable for generating a braking force, and upon the braking state of the brake being canceled, said brake lever being thrown while the brake release knob urged by a release rod disposed in a brake lever distal end part being depressed against an urging force, the assembled structure of the brake release knob comprising:

• a cap fixed in said brake lever distal end part, and formed so as to allow the brake release knob to be inserted,
• said brake release knob being comprised of a head part and a leg part extending from the head part, the leg part having a flange part engaged with an innermost end of said cap upon the leg part being inserted into said cap,
• a distal end part taperedly extending from a shoulder part of said release rod being inserted closer to a center of said cap than the leg part of said brake release knob, and the flange part of said brake release knob being sandwiched between said shoulder part and the innermost end of said cap under pressure,
• wherein said cap has a fixing claw which is formed by giving a cut in a peripheral wall, the fixing claw having a protrusion part protruded toward an inner peripheral wall of said brake lever, and
• said brake lever has an engaging part provided by forming a recess or hole in both side walls for allowing the protrusion part of said cap to be engaged therewith for fixing said cap.
