    摘要: A tool unit for a cutting device includes a rotary blade, a blade case for covering at least a part of the blade case, and a drive device mounted to the blade case for rotatably driving the rotary blade. A handle is attached to the drive device. The blade case has a front support portion. The handle has a rear support portion. When the tool unit is used for a portable cutting device, the front support portion can be vertically pivotally supported by a front portion of the base, and the rear support portion can be supported by a guide member such that a position of the rear support portion can be changed relative to the guide member for enabling adjustment of a cutting depth of the rotary blade into the workpiece. When the tool unit is used for a table cutting device, the front support portion can be vertically pivotally supported by the table.

    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: A battery-operated driver-drill (1) includes an epicycle reduction gear unit (8) which encases a switchover sleeve (26) having inner teeth (27) and outer teeth (28). The gear unit (8) is rotatably mounted on second and third internal gears (19, 20) and integrally slidably connected with a slide pate (37). By operating the slide plate (37), the switchover sleeve (26) may be slid between a first position, in which the slide plate (37) engages one of the second and third internal gears (19, 20) while engaging axial ridges (29) of a first gear case (5), and a second position, in which the slide plate (37) simultaneously engages both the second internal gear (19) and a first carrier (10) adjacent to the second internal gear (19) while disengaged from the axial ridges (2).

    摘要: According to the present invention there is provided a highly reliable position sensor capable of preventing the entry of foreign matters such as water and dust from the exterior into a receptacle chamber formed within a housing. Formed in the housing are a mounting opening to be mounted in a sealed state to a throttle body and a receptacle chamber having an opening. The receptacle chamber and the mounting opening are partitioned from each other by a partition wall. A sensor body is mounted into the receptacle chamber and the opening of the chamber is covered with a cover, then a clearance formed between the opening and the cover is filled and sealed with a thermosetting resin such as an epoxy resin. A communication hole for communication between the receptacle chamber and the mounting opening is formed through an operating shaft which is rotating a sliding-element receiver of the sensor body. While the thermosetting resin is heated, the air expanded in the receptacle chamber is allowed to escape through the communication hole to the exterior. After a throttle position sensor as the position sensor has been attached to the throttle body, the communication hole formed in the operating shaft is shut off from the exterior by the mounting surface for the throttle body.
