摘要： One aspect according to the present invention includes a switch device for a power tool. The switch device includes a switch lever operable to move between an ON position for activating the power tool and an OFF position for stopping activation of the power tool. An on-lock mechanism can lock the switch lever in the ON position. An off-lock mechanism can lock the switch lever in the OFF position. The operation for making the on-lock mechanism effective and the operation for releasing the off-lock mechanism are performed by operating an operation member in different directions from each other or by operating two separate operation members.

摘要： A dust collection cover may be made from resin for achieving a reduction in its typical weight. In such a configuration, a disk-shaped grinding stone for grinding a steel material is preferably not attachable due to interference of an attachment-restricting portion. It is preferred that only a cup-shaped diamond wheel for work that generally does not produce heated iron powder or the like is attachable.

摘要： It is accordingly an object of the invention to provide a technique of cooling a power tool which further improves cooling effectiveness of the power tool. According to the invention, a power tool is provided that includes a driving motor, a tool bit, a power transmitting mechanism, a tool body and a cooling fan. The power tool further includes first and second cooling air passages. The first cooling air passage is disposed within the tool body and flows cooling air into the tool body by using the cooling fan. The second cooling air passage is provided within the tool body and takes outside air into the tool body by using the flow of the cooling air through the first cooling air passage. The cooling air within the first cooling air passage can be cooled by mixing outside air taken into the tool body via the second cooling air passage and therefore, the cooling air can further effectively cool components within the power tool. As a result, cooling effectiveness of the power tool can be improved.

摘要： A power tool (1) includes a tool body (3) on which a battery (10) as a power source is mounted. A switch (7) is electrically connected to the battery for supplying power to a motor (6) that is disposed within the tool body. An ON lock mechanism (12,20) serves to lock the switch in an ON position. The ON lock state of the switch can be released or the switch can be turned OFF when the battery is removed from the power tool.

摘要： In an electric disc grinder, there is provided, between a driven gear and a spindle in a torque transmission system, a C-shaped spring member capable of elastic deformation in a diameter enlarging direction. With respect to the rotating direction, the spring member is engaged with a driving protrusion of the driven gear and a driven protrusion of a joint sleeve of the spindle; when transmitting the rotation of the driven gear to the spindle, the spring member undergoes elastic deformation in the diameter enlarging direction depending on the driven side load, thereby mitigating the starting shock. An abutment surface of the driven protrusion is formed as an inclined surface causing an end portion of the spring member contacting with the abutment surface to slide radially outwards. As a result, the spring member can easily undergo elastic deformation in the diameter enlarging direction.
