    摘要: A pair of stoppers (47) capable of moving back and forth in an axial direction of a spindle (5) are provided on an outer periphery of a tubular portion (9a) for supporting the spindle (5). As a pair of projections (49) provided on a first change ring (32) are moved in conjunction with the rotation of the first change ring (32) which is capable of changing over the operating mode of a percussion driver drill, the stoppers (47) move back and forth in the axial direction. During a percussion mode and a drill mode, the stoppers (47) abut against a flat washer (50) for fixing an internal gear (13) to restrict the forward movement of the flat washer (50), while, during a clutch mode provided in the first change ring (32) as a third changeover position, the stoppers (47) move away from the flat washer (50). A pair of washers (40, 41) superposed on each other in the axial direction of the spindle (5) are interposed between the first change ring (32) and a second change ring (39). The washer (40) has a click (45) capable of engaging in one of recesses (59) formed in the first change ring (32). The washer (41) has a click (46) capable of engaging in one of recesses (58) formed in the second change ring (39).

    摘要: A technique that increases operability in changing the rotational speed of a spindle in a power tool. The rotational speed can be changed in three levels by utilizing a planetary gear mechanism. The third gear position is located in an intermediate position in the sliding direction of the speed changing part. The first speed change position is located on one side of the third speed change position. The second speed change position is located on the other side of the third speed change position. During operation, shifting between the first and third speeds can be done without going through the second speed each time. Further, shifting between the second and third speeds can be done without going through the first speed. Therefore, speed change shifting can be facilitated.

    摘要: It is an object of the invention to provide a technique that contributes to increased operability in changing the rotational speed of a spindle in a power tool b which the rotational speed of the spindle can be changed in three levels by utilizing a planetary gear mechanism. A representative power tool is characterized in that the third gear position in which the spindle is rotated at the third speed is located in an intermediate position in the sliding direction of the speed changing part The first speed change position in which the spindle is rotated at the first speed is located on one side of the third speed change position, and the second speed change position in which the spindle is rotated at the second speed is located on the other side of the third speed change position. Therefore, during processing operation by using the power tool, shifting operation between the first and third speeds which is frequently performed can be done without the need to go through the second speed area each time. Further, shifting operation between the second and third speeds which is also frequently performed can be done without the need to go through the first speed area. Therefore, shifting operation for speed change can be facilitated, so that ease of use can be improved.
