    摘要： The present invention provides a power tool that can be used at a position away from the external power source. The power tool includes a housing, a motor, an end tool, a battery pack, and an inverter. The housing has an upper side portion and a lower side portion. The motor is supported by the housing and driven by alternate-current power. The end tool is supported by the housing and rotatably driven by the motor. The battery pack outputs direct-current voltage. The inverter is disposed on the upper side portion and at a position higher than the motor and configured to convert the direct-current voltage outputted from the battery pack into alternate-current voltage and to supply the motor with alternate-current power.

    摘要： A chainsaw in which a remaining amount of chain oil to be supplied to a saw chain can be easily checked is provided. In a chainsaw 1 including: a saw chain 6 driven by a motor embedded in a main body; and an oil tank 11 in which the chain oil to be supplied to the saw chain 6 in wood cutting process is stored, an illumination unit (LED 15) is provided in vicinity of the oil tank 11. In this manner, the chain oil of the oil tank 11 positioned on a left side of the LED 15 can be illuminated. This illumination unit is configured to be used also as an illuminating device for illuminating the vicinity of the saw chain 6, that is, an area indicated by dotted lines from 21c to 21d. According to the present invention, in a dark location, the remaining amount of the chain oil can be checked, and besides, a positional relationship among the chainsaw 1 main body, the saw chain 6, and the periphery thereof can be easily visually checked, so that the working efficiency can be improved.

    摘要： A chainsaw having improved cutting workability is provided. A chainsaw (10) is used to cut an object to be worked by a saw chain (22). A chainsaw main body (12) is provided with an electric motor (11) and a sprocket (19), and a guide bar (21) around which the saw chain (22) is wound is provided on the chainsaw main body (12). The guide bar (21) is attached to the chainsaw main body (12) by a screw member (36) serving as an attaching member. A load sensor (41) detects whether or not the guide bar (21) is attached to the chainsaw main body (12). Rotation of the saw chain (22) is prohibited based upon a signal from the load sensor (41) when the guide bar (21) is not attached to the chainsaw main body (12).
