Title:
WORK MACHINE
Document Type and Number:
WIPO Patent Application WO/2021/199816
Kind Code:
A1
Abstract:
The present invention improves mounting properties while suppressing vibration of a battery pack. In a housing 12 of a hammer drill 10, a handle housing 16 is linked to a body housing 13 by a vibration-preventing mechanism 30 so as to be capable of moving relative to the body housing 13. A battery pack 70 is removably mounted in the handle housing 16, and a battery pressing member 80 is provided to the body housing 13. The battery pressing member 80 is positioned on the forward side with respect to the battery pack 70. Therefore, even with a setting in which the battery pack 70 is not pressed by the battery pressing member 80 at an initial position of the handle housing 16, the battery pack 70 presses the battery pressing member 80 when the handle housing 16 is pushed in toward the forward side by a worker during working of the hammer drill 10, therefore making it possible for the battery pack 70 to be pressed by the battery pressing member 80.
