A stencil leading end mounting device of a printing drum of a rotary stencil printer for clamping a stencil leading end between a stencil leading end supporting surface 70 of a base member 72 and a clamping surface 74 of a clamp member 76, the clamp member being biased at a drive portion 82 by a lever member 108 of an actuator to be tilted open about a linear pivot axis P, wherein the linear pivot axis P is defined by a contact point between a convex cam 115 and a bearing surface provided between the clamp member 76 and the based member 72, so as to move from a side of the clamping surface toward a side of the drive portion as the clamp member is more tilted.
