Claims

[Claims for Utility Model Registration] A sector that is fixed to the vehicle body and has a ratchet formed along an arc centered on the first axis, and a sector that has a cylindrical part on the distal end side and the first axis on the proximal end side. a lever body disposed to be rotatable about a second axis; and a lever body disposed to be rotatable about a second axis parallel to the first axis and engaged with the ratchet; a pole that allows rotation in one rotation direction but prevents rotation in the opposite direction; and one end is connected to the pole so as to be relatively rotatable, and the other end is inserted into the cylindrical part. a first spring member disposed substantially concentrically within the cylindrical portion to engage the pawl with the ratchet by biasing the release rod toward the distal end of the lever body; and the lever. a knob that is disposed so as to be pushed into the cylindrical portion from the opening at the tip of the main body, and releases the engagement between the pawl and the ratchet via the release rod when the knob is pushed in; An insertion hole is provided through which the knob protruding from the opening is inserted,
In the parking brake operating device including a grip made of an elastic body that is held when the lever body is rotated, the knob is arranged so as to be able to come into contact with and separate from the release rod, and the knob is arranged so as to be able to come into contact with and separate from the release rod,
The pawl is always urged in the direction of protruding from the tip opening by a spring member, and a slight gap is formed between the pawl and the release rod when the pawl is engaged with the ratchet.
A parking brake operating device characterized in that its protruding position is defined by a stopper.
