A shaving razor comprises: a handle; a blade unit that is mounted at the end of said handle and includes a guard, at least one blade having a cutting edge, and a cap; and a parallelogram, four-bar linkage connecting the blade unit to the handle. The linkage is made of an integral plastic piece and includes two elongated members, a proximal end member connected to the handle, and a dist al end member connected to the blade unit. Each elongated member is pivotally connected via resilient first living hinges at respective ends to the proximal end member and the distal end member, the first living hinges providing up and down movement of the blade unit along a displacement axis that is transverse to a plane through the guard and cap.
