Abstract
A workability of a driving work machine is improved by reduction in vibration transmitted to a housing. A driving work machineincludes: a cylinderapplying a rotational force to a tip tool; a pistonapplying a striking force to the tip tool; a driving source generating a power; a switching partmaking switching between at least two operational states including a rotational striking state of transmitting the power as a striking force and a rotational force to the tip tool and a rotational state of transmitting the power as the rotational force but not transmitting the power as the striking force to the tip tool; and a housing. The cylinderincludes a pushing partpushing the switching partrearward, the switching partis able to switch an operational state of the cylinderby the rearward movement caused by the pushing force of the pushing part, and a rubber annular memberserving as an anti-vibration part is arranged between the pushing partand the preventing part
