SUMMARY OF THE INVENTION The present invention aims to provide a technique that contributes to the driving ability of a hammer member in a working tool. Moreover, ίΐί: the purpose of the present invention is to provide a kind of driving force; and two components in the direction of the direction: the spring 3 of the coil spring is moved backwards in the opposite direction to the driving direction and or The 襕 , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , As a characteristic structure, the drive mechanism has a roller, which is engaged with the hammer member after the driving action, and penetrates into a movement of eight and makes the hammer component by the action of the driving direction of the knife in the _ motion. When the auxiliary member 1 releases the engagement with the roller when the sub-member that transmits the ==:, the member is engaged with the disassembled member, thereby receiving the hammer from the roller instead of the pure one. The hammer that moves back through the roller and moves backward is received, and the received hammer member is engaged with the hammer member at the receiving position or at the position of the receiving position (four). The blood is created by the auxiliary member from the roller. The position of the (4) sub-component is used, although the 疋 is used in the following form. The roller causes the hammer member to retreat = when the connecting member is at the retreating end, at the retreating end, the auxiliary member 攸 receives the hammer material, but the receiving position is not limited to the receding end, and may be located close to the receding end. The following area can be used. _ 1325811 In the state where the roller moves the hammer member back to the retreating end, in the moving direction of the hammer member, from the retracted end of the hammer member to the center between the rollers, change &amp; a roller member that moves backwards is placed in a region between the center of rolling of the roller and the retracted end of the hammer member when the retracting end is placed. For example, after the hammer member is moved by the roller, the engagement with the roller is released, In this case, the hammer member is driven by the spring force of the coil spring: when the member is driven as described above, the position at which the hammer member is lightly engaged with the light is released. The intersection position of the straight line in the direction perpendicular to the moving direction of the center of the transmissive center. Therefore, in the lightness of the disk, the position of the rolling center is closer to the side of the retreating end, and the auxiliary member is retracted. When the member is configured as described above and the release position is reduced only when the hammer member is moved backward, the engagement position of the auxiliary member and the hammer material can be set to a position closer to the backward end. The "axial state" of the towel is pure (four) in the hammer component = state '. In addition, as a pro-"arc-shaped motion", the deviation is included in the form of a report from the center of rotation of the rotating body that performs the rotational motion, or the crankshaft that performs the rotational motion. &quot;&quot;. The form of the slap on the slap, etc. According to the present invention, the hammer portion is retracted by rolling contact between the 1st and the moving phases = the hammer member: sub = can = can__. In addition, '_=:, in addition to the movable reading of the leaking component of the pure material, and the second type: the mechanism to be driven by the mechanism 1 is preferably a form that is driven by other mechanisms that are different in light. Move == two: for:: The component is reconciled from the light and the composition of the thousand counties. The hammer member received by the auxiliary member releases the engagement with the 5H auxiliary member at the position of 7: the receiving position or the position where the receiving position is moved backward, thereby relieving the elastic force stored in the coil spring. The direction is a straight-line driving action. According to the present invention, it is possible to disengage the auxiliary portion in the vicinity of the retreat end by arranging the engagement of the member in the rolling contact mode by the auxiliary member engaged in the sliding contact mode.
