Abstract
A vehicle hand brake lever assembly for actuating the vehicle parking brake. The lever assembly includes an axially slidable plunger mounted on a support and having one end connected with a brake actuating member.

The lock member is axially slidably received in the guide member and provided with a cam profile for cooperation with a cam profile provided on the sleeve. The lock member is spring biased toward the sleeve so that the cam profiles are normally engaged with each other to thereby maintain the handle shaft at a predetermined relationship with respect to the plunger. The lock member further has axial projections and the guide member has an end wall formed with cutouts for receiving the axial projections on the lock member when the handle shaft…
