Setting screw for a control lever device

A control lever device for a vehicle, wherein said device comprises:

• a support structure with means for connecting the device to a handlebar;
• a cylinder-piston unit connected to the support structure;
• a lever pivotally connected to the support structure along an angular actuation stroke;
• a transmission portion associated with the device such as to transmit an actuation movement from the lever to the cylinder-piston unit;
• a threaded hole formed in the device to house an adjusting screw acting on the lever such that a rest position of the lever relative to the support structure can be adjusted by rotating the adjusting screw, wherein the adjusting screw comprises:
• a screw body with a threaded shank that is screwed into a corresponding threaded hole of the lever device;
• and
• a locking body being pivotally connected to the screw body, the locking body comprising:
• an anchoring tab configured to engage an anchoring seat of the lever device such as to prevent the locking body from rotating relative to the threaded hole of the lever device;
• an elastic annular locking plate seated in an annular seat of the shank, so as to prevent displacement of the locking body along the shank of the screw body and detachment of the locking body from the shank, the annular elastic plate having one or more deformable projections which elastically engage at least one cavity formed in the screw body at said annular seat such as to counteract the rotation of the locking body relative to the screw body to a certain extent,
• wherein said screw body comprises an actuating head removably connectable to a first end of the shank for unitary rotation therewith and a funnel shaped seat directly formed at a second end of the shank opposite the actuating head, wherein both the actuating head and the funnel shaped seat have a diameter which is greater than a diameter of the threaded shank, wherein said annular seat is adjacent said actuating head and said cavity is formed in the actuating head, wherein the first end of the shank has a front surface from which an elongated connecting portion protrudes for connecting the shank to the actuating head, such that a contact surface of the actuating head forming said cavity faces said front surface, wherein the front surface works together with a part of the elongated portion and the contact surface said annular seat to house the locking body in a manner that the engagement of the projection of the locking plate with the cavity on the contact surface remains constant independently from axial displacements of the adjusting screw within the threaded hole.

• said anchoring seat extends in the longitudinal direction of the threaded hole and allows the anchoring tab to be displaced along said direction, thereby preventing the locking body from rotating together with the shank of the adjusting screw and
• the anchoring tab is bent with respect to the annular locking plate in a longitudinal direction of the shank.
