Abstract

The invention is based on a portable power tool having a vibration-damped handle (10) which has two legs (12, 14) running in the longitudinal direction (48) of the portable power tool and which is motionally coupled to its housing (28), wherein at least one lever (20, 22; 20a, 22a; 20b, 22b) oriented transversely to the longitudinal direction (48) is coupled to each of the two legs (12, 14) at an articulation point (16, 18; 16a, 18a), and wherein the levers (20, 22; 20a, 22a; 20b, 22b) are coupled to a joint region (50) lying between the two legs (12, 14) of the handle (10). It is proposed that each lever (20, 22; 20a, 22a; 20b, 22b) have a bearing point (24, 26; 24a, 20 26a; 24b, 26b) between the joint region (50) and the respective articulation point (16, 18; 16a, 18a).
