<p>The nail clipper contains a pair of blade bodies each having a cutting edge, a lever to be operated for bringing the cutting edges of the blade bodies into press contact with each other and a supporting shaft for linking the lever to the blade bodies; the cutting edges of the blade bodies being brought into press contact with each other by pressing the blade bodies with the lever against resilience of the blade bodies. The nail clipper is provided with bosses formed either on the lever or on the supporting shaft, so as to allow the supporting shaft to pivotally support the lever; and grooves formed on the rest of the supporting shaft and the lever, with which the bosses are engaged. Each groove has a mouth portion through which the boss is engaged and disengaged, a guiding portion capable of pivotally supporting the boss, and a connecting portion connecting the mouth portion and the guiding portion to each other.
