Abstract:
1. A combustion type driving tool comprising: a housing; a combustion chamber frame which is provided in said housing, and can move in one direction and in the other direction thereby to define a combustion chamber when the combustion chamber frame has moved in the other direction; and moving means which can select either of a manual operation valid state and a manual operation invalid state, and permits said combustion chamber frame to move in the other direction by manual operation, only in the manual operation valid state, wherein said moving means includes a link mechanism, said link mechanism having a connection part connected to said combustion chamber frame at one end of the link mechanism, an operation part which can be pressed at another end of the link mechanism, and a rotation shaft provided between said connection part and said operation part and extending in a direction substantially perpendicular to a moving direction of said combustion chamber frame thereby to be selectively positioned, so that said manual operation valid state can be obtained by said positioning, wherein said link mechanism is constructed in such a manner that said operation part can rotate around said rotation shaft when the operation part is manually pressed, and said connection part can move in the other direction.
