Document Type and Number:

Japanese Patent JP2018086710

Kind Code:

A

Abstract:

PROBLEM TO BE SOLVED: To provide an electric tool capable of surely preventing a magnet for rotation position detection from falling from a rotary member.SOLUTION: An electric tool includes: a brushless motor (4) which is a driving source; a motor shaft (43) of the brushless motor (4); a bearing (22) for pivotally supporting the motor shaft (43); a bearing storage hole (23) in which the bearing (22) is supported; and a housing (2) in which the bearing storage hole (23) is formed. At the motor shaft (43), a rotary member (9) is connected in which a magnet (46) for rotation position detection is embedded. The rotary member (9) is provided so as to be adjacent to the housing (2), and on a side surface opposing to the housing (2) of the rotary member (9), an embedding hole (94) is formed for embedding the magnet (46) for rotation position detection.SELECTED DRAWING: Figure 4
