Claim:
1. A biasing force adjustment device comprising: a cylindrical component having a first thread; a reciprocate component accommodated to reciprocate in the cylindrical component; a biasing portion that biases the reciprocate component in a first direction along a central axis of the cylindrical component; and a biasing force adjustment component that adjusts a biasing force of the biasing portion in the cylindrical component, wherein the biasing force adjustment component has the first insertion hole is located on a side of the biasing force adjustment component opposite from the biasing portion through the biasing force adjustment component in the axial direction; the regulation part has a second insertion hole having an inside diameter larger than an inside diameter of the first insertion hole; the regulation part has a sloped surface at an edge of the second insertion hole adjacent to an opening of the regulation part; and the sloped surface is inclined relative to the central axis, and is inclined away from the central axis in a second direction opposite from the first direction; wherein the sloped surface has an inclined angle greater than an inclined angle for the second insertion hole, prior to said deformation in the radial direction by the external force; an outside diameter of the stopper part is larger than the inside diameter of the first insertion hole, and the outside diameter of the stopper part is smaller than the inside diameter of the second insertion hole.
