Claims

[Scope of utility model registration request]

A plunger with a handle attached to one end is attached to the vehicle body so that it can slide in the axial direction and rotate around the axis,
A brake activation wire is directly or indirectly connected to the other end of the plunger, and when the driver holds the handle and pulls the plunger to activate the brake, the plunger is held in the pulled-out position against the brake reaction force, In a stick-type handbrake for a vehicle, which is provided with a locking mechanism that releases this holding by rotating a plunger in one direction, the handle is provided with a handle shaft portion that projects from a portion near one end of the grip portion at right angles to the grip portion; A sleeve and a bottomed cylindrical guide member with the sleeve fitted into the opening are fixed to either one of the shaft portion and one end of the plunger, and the other end is arranged to extend the bottom wall of the guide member in the axial direction. The locking member is movably inserted through the guide member and is integrally coupled with a locking member slidably and rotatably fitted inside the guide member, and the locking member and the sleeve have opposite end surfaces. Rotation having a plurality of troughs and a plurality of peaks in which the rotational position of the handle relative to the plunger is maintained at a plurality of predetermined positions by the force of a compression spring interposed between the locking member and the bottom wall of the guide member. A cam surface is formed on the bottom wall of the guide member and an end surface of the locking member opposite to the bottom wall. A plurality of notches and protrusions that are engaged when the handle is pulled are formed asymmetrically with respect to the axis of the plunger, and the notches and the protrusions are formed in a state where the handle occupies the prescribed position with respect to the plunger. A safety device for a cane-type handbrake for a vehicle, characterized in that the interval is set to be wider than the axial dimension of the rotating cam surface.
