A parking brake operating apparatus (10), comprises (a) a supporting member (12) disposed integral with a vehicle, (b) an operating member (16) disposed in the supporting member to pivot about a first axis, and actuates a parking brake by a braking operation from an initial position thereof, (c) a ratchet (30) having many engaging teeth (28) formed along an arc centering on the first axis, and disposed in the supporting member integrally therewith, and (d) a pawl (32) disposed in the operating member, riding over the many engaging teeth during the braking operation of the operating member, and engaging with the teeth in the brake actuating position of the operating member to prevent returning pivotal movement of the operating member toward the initial position side for maintaining an actuating state of the parking brake. In such parking brake operating apparatus, a first engaging tooth (28a) in the many engaging teeth (28) of the ratchet (30) over which the pawl (32) rides first during the braking operation of the operating member (16) from the initial position is determined higher in a height than other engaging teeth (28e). |
