Title:
WORK MACHINE
Document Type and Number:
WIPO Patent Application WO/2021/153134
Kind Code:
A1
Abstract:
The present invention illuminates the periphery of a tip tool, while preventing an increase in the number of components. A router 10 includes an illumination unit having an LED, and the illumination unit is accommodated in an illumination accommodation unit of a retention ring 60 and retained by the retention ring 60. Here, a restriction unit 63 of the retention ring 60 is arranged adjacent to a lower side of a positioning rib 44A of a stator 43 and restricts downward movement of the stator 43. Thus, the illumination unit can be retained using the retention ring 60 that restricts the downward movement of the stator 43. Accordingly, the illumination unit can be mounted in the router 10 using a member that retains the illumination unit and a member that restricts the downward movement of the stator 43 as a common member. In this manner, the periphery of a tip tool 46 can be illuminated by the illumination unit, while preventing an increase in the number of components.
