Title:
POWER WORK MACHINE
Document Type and Number:
Japanese Patent JP2019005847
Kind Code:
A
Abstract:
To provide a power work machine which increases degree of freedom in arrangement of an acceleration sensor, and can adequately detect acceleration in a rotation direction of a tip tool generated in a housing.SOLUTION: A power work machine includes: a housing 2; a motor 3 which is housed in the housing 2 and has a rotation shaft 31; an output part 7 which is driven by the motor 3 and to which a tip tool P can be attached and detached; a power transmission part which can drive the tip tool P in a first direction by transmitting rotation movement of the rotation shaft 31; an acceleration sensor 8 which is supported by the housing 2 and can detect a motion state of the housing 2. The acceleration sensor 8 is supported by the housing 2 so that an allowable movement amount of the acceleration sensor 8 with respect to the housing 2 in the first direction becomes larger than an allowable movement amount of the acceleration sensor 8 with respect to the housing 2 in a second direction intersecting the first direction.SELECTED DRAWING: Figure 2
