A lever device (100) includes: a bracket (18) fixed to a vehicle; a lever (12) pivotally held by the bracket (18) and pivoted to apply tension to a wire (19) connected to brake units (22, 23) of wheels, thereby applying a brake to the wheels; a pole lever (14) engaged with one of teeth (15) formed in the bracket (18) to keep the lever (14) at a selected pivot angle and pivotally held by the lever (12); a release rod (13) connected to the pole lever (14),- and a switch (11) that pushes the release rod (13) to disengage the pole lever (14) from the tooth (15). The interval between part of the teeth (15), with which the pole lever (14) is engaged when the lever (12) is at a first pivot angle, is wider than the interval between another part of the teeth (15), with which the pole lever (14) is engaged when the lever (12) is at a second pivot angle that is larger than the first pivot angle.
