Driving tool

A driving tool includes a housing, a magazine, a cylinder head, a push lever, a cylinder, a combustion chamber frame, a piston, an injection part, and a fastener feeding unit. The housing has one end portion and another end portion. The magazine is connected to the housing and accommodating a fastener. The cylinder head is disposed at the one end portion. The push lever is movable relative to the housing upon pressure contacting a workpiece in a moving direction. The cylinder is fixed to the housing. The combustion chamber frame is movable in the housing in accordance with the push lever and selectively defining a combustion chamber in cooperation with the cylinder. The piston is slidably reciprocally movable relative to the cylinder and displaced upon expansion of air/fuel mixture in the combustion chamber. The injection part is connected to the another end portion of the housing and having an injection passage in communication with the magazine. The fastener feeding unit feeding the fastener to the injection passage in accordance with the movement of the push lever. The push lever includes a first guiding part configured to be slidably engaged with the fastener feeding unit. The fastener feeding unit is movable between an initial position and a feed position positioned downstream of the initial position in a feeding direction in which the fastener is fed. The fastener feeding unit slidably moves from the initial position to the feeding position with respect to the first guiding part for feeding the fastener downstream in the feeding direction in accordance with the movement of the push lever upon pressing the workpiece.
