and a counterweight 6 having a longitudinally extending member 12 mounted to move in an antiphase relationship with respect to the ram 4 and parallel to the ram 4,
The counterweight 6 has an upper transverse piece 13 and a lower transverse piece 14 extending between longitudinally extending members 12, the transverse pieces having an abutment surface A extending at right angles to the axis of the ram 4 and a guide surface for the ram 4. It has guide surfaces 15, 16 which extend symmetrically with respect to the axis of the ram 4 so as to move along the surfaces 15, 16, so as to ensure that the crankshaft 3 engages the abutment surfaces A of the transverse pieces 13, 14. Features a jigsaw. (2) The jigsaw according to claim 1, wherein the geometric center O of the crankshaft 3 and the crank pin 9 are arranged on both sides of the rotation axis 11 of the crankshaft 3. (3) A jigsaw according to claim 1, characterized in that the casing (1) has a guide member (25) for the longitudinally extending member (12) of the counterweight (6). (4) The jigsaw according to claim 1, wherein the upper and lower lateral pieces 13, 14 of the counterweight
A jigsaw characterized in that the surface B of the crankshaft 3 that engages with the jigsaw is spherical. (5) In the jigsaw according to claim 1, the ram 4
A jigsaw, characterized in that, together with the guide surfaces 15, 16, they form a space 17, and in one of the spaces 17 an elastic member 18 is provided.
