Abstract: A slicer with which the thickness of sliced food can be varied includes a movable receiving part that receives sliding food and is subjected to downward pressure from the food, the movable receiving part not moving downward due to the pressure even if a means for securing the receiving part in place is not separately provided. An adjustment member for moving a vertically mobile first receiving part is mounted in a frame of the slicer so as to be forwardly and rearwardly movable. A means for moving the adjustment member is a worm that is provided on a drive shaft. A deflection mechanism is present between the adjustment member and the first receiving part which converts the forward and rearward motion of the adjustment member into vertical motion of the first receiving part.

Abstract: 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.

Abstract: First stopper face (7b) is provided on each of click teeth (7) of a click teeth portion 8 of a click mechanism (14) affording a click feeling during the rotation-operation of a rotary knob (11). Second stopper face (13b) is provided on a tooth portion (13) of a click piece (10). The first stopper face (7b) and the second stopper face (13b) cooperate to prevent the rotary knob (11) from rotating in a direction opposite to a direction indicated by an arrow A. Consequently, there is no need for providing a stopper as an additional component.
