    Abstract: A hammer drill (100) comprises a main housing (101), a hand grip (109) connected to the main housing (101) via a compression coil spring (171). In the hammer drill (100), a hammer bit (119) is driven by a motion converting mechanism (120), a hammering mechanism (140) and a rotation transmitting mechanism (150), and thereby performs a hammer-drill operation. During the hammer-drill operation, the hand grip (109) is moved against the main housing (101) in a state that biasing force of the compression coil spring (171) is applied. Further, the hammer drill (100) comprises a counterweight (190). The gravity center of the counterweight (190) is set to be lower than the upper edge of a cylinder (129) which is one component of the motion converting mechanism (120).

    Abstract translation: 锤钻(100)包括主壳体(101),通过压缩螺旋弹簧(171)连接到主壳体(101)的手柄(109)。 在锤钻(100)中,锤头(119)由运动转换机构(120),锤击机构(140)和旋转传递机构(150)驱动,从而进行锤钻操作。 在锤钻操作期间,在施加压缩螺旋弹簧(171)的偏置力的状态下,手柄(109)抵靠主壳体(101)移动。 此外,锤钻(100)包括配重(190)。 配重(190)的重心被设定为低于作为运动转换机构(120)的一个部件的气缸(129)的上边缘。
