Problems solved by technology

Therefore it is difficult to suppress this vibration of the handle with the hand holding the handle
[0005] Also, in the case of a belt grinder, since the motor shaft of the motor is perpendicular to the length direction of the handle, the motor protrudes in the width (or lateral) direction of the handle
This makes it difficult to use a belt grinder in tight spaces, such as the inside of pipes in plumbing (e.g., electrical conduit or water pipes), because the motor becomes an obstacle

Embodiment Construction

[0014] Hereinafter, embodiments of the present disclosure will be explained. The following embodiments are merely examples of various embodiments of the present disclosure. Various modifications to the following embodiments in view of the general arrangement and the like are possible as long as the purpose of the present disclosure is achieved. For convenience of explanation, forward (F), backward (B), left (L), right (R), upward (U) and downward (D) directions are used in the following explanation. However, it is not intended to limit the direction of use of the electric power tool according to this embodiment.

[0015] (Example)

[0016] will refer to Figures 1A to 2B An electric tool (or power tool) 1 according to the present embodiment is explained.

[0017] like Figure 1A and 1B As shown, the power tool 1 is configured, for example, as a hand-held belt grinder. Such a belt grinder is a tool for grinding a target object by a polishing surface of an endless belt rot...

Abstract

Power tools that enable users to easily suppress the vibration of the motor with their hands and are usable even in narrow spaces and outdoors. The electric tool (1) of the present disclosure comprises a grinding mechanism (3), a motor (10), a battery pack (4) and a casing (21). The motor (10) is configured to drive the grinding mechanism (3). The battery pack (4) is configured to supply power to the motor (10). The grinding mechanism (3), motor (10) and battery pack (4) are fixed to the housing (21). The motor (10) has a rotating shaft (101) configured to transmit rotational drive power to the grinding mechanism (3). The housing (21) has a handle (22) that allows the user to hold it. Grinding mechanism (3), motor (10), battery pack (4) and handle (22) are arranged in one direction. The rotating shaft (101) of the motor (10) is elongated in the one direction.

Description

technical field [0001] The present disclosure relates generally to power tools, and more particularly, to a power tool equipped with an electric motor. Background technique [0002] Document 1 (JP2002-233942A) discloses a belt grinder as an example of an electric motor-equipped electric tool. The belt grinder described in Document 1 is equipped with a handle, a motor, a driving roller, an arm, a driven roller, and a grinding belt. The handle allows the user to hold. The motor is provided at the front end of the handle. The motor has a motor shaft perpendicular to the length direction of the handle. The drive roller is fixed to the motor shaft of the electric motor. The handle is provided with an arm protruding forward from the drive roller. The driven roller is provided at the front end portion of the arm so as to be allowed to rotate with the driven roller separated from the driving roller. A grinding belt loops around the drive and driven rolls. [0003] With a belt...
