Abstract

A power tool includes a motor, an output part, a housing, a control circuit board, and a panel. The motor includes a rotor rotatable about a motor rotation axis extending in a front-rear direction. The output part is disposed forward of the motor and is rotated by a rotational force of the rotor. The housing includes: a motor housing part that houses the motor; a grip part that extends downward from the motor housing part; and a battery holding part that is connected to a lower end of the grip part. The control circuit board is housed in the grip part and is configured to control the motor. The panel is disposed at a rear portion of the battery holding part and is manipulated to change a control method of the motor.

Claims (69)

1 . A power tool comprising:

a motor, which includes a rotor rotatable about a motor rotation axis extending in a front-rear direction;

an output part, which is disposed forward of the motor and is rotated by a rotational force of the rotor;

a housing that includes

a motor housing part that houses the motor,

a grip part that extends downward from the motor housing part, and

a battery holding part that is connected to a lower end of the grip part;

a control circuit board, which is housed in the grip part and is configured to control the motor; and

a panel, which is disposed at a rear portion of the battery holding part and is manipulated to change a control method of the motor, wherein

the control circuit board includes:

a motor terminal connected to the motor; and

a body-side terminal to which a battery pack is connected.

2 . The power tool according to claim 1 , further comprising

a resin part that supports the panel.

3 . The power tool according to claim 2 , wherein

the panel is in contact with the resin part.

4 . The power tool according to claim 2 , wherein

the panel is fixed to the resin part.

5 . The power tool according to claim 2 , wherein

the panel faces a circuit board, and

the resin part holds the circuit board.

6 . The power tool according to claim 5 , wherein

the panel includes an optically transmissive part, and

the circuit board supports a light emitting element that irradiates the optically transmissive part with light.

7 . The power tool according to claim 1 , wherein

in a left-right direction, a center of the panel coincides with a center of the battery holding part.

8 . The power tool according to claim 1 , wherein

the panel is disposed rearward of a rear end of the grip part.

9 . The power tool according to claim 1 , wherein

the panel is disposed rearward of a rear end of the motor housing part.

10 . The power tool according to claim 9 , wherein

a rear end of the control circuit board is positioned forward of a front end of the battery holding part.

11 . The power tool according to claim 1 , wherein

the panel is disposed rearward of the control circuit board.

12 . The power tool according to claim 1 , wherein

a surface of the control circuit board extends along a direction in which the grip part extends.

13 . A power tool comprising:

a motor, which includes a rotor rotatable about a motor rotation axis extending in a front-rear direction;

a speed reducing mechanism configured to decelerate rotation input from the motor;

a hammer configured to be rotated with an output of the speed reducing mechanism;

an output part configured to be rotated tother with the hammer and to be impacted in a rotation direction by the hammer;

a housing, which includes

a motor housing part that houses the motor,

a hammer housing part that houses a hammer,

a grip part that extends downward from the motor housing part,

a support part that is disposed forward of the grip part and that extends downward from the hammer housing part, and

a battery holding part, which is connected to a lower end portion of the support part and to which a battery pack is connected by being slid; and

a control circuit board, which is housed in the housing and is configured to control the motor; and

a panel, which is disposed at either or both of a lower portion of the grip part and a rear portion of the battery holding part and is manipulated to change a control method of the motor.

14 . The power tool according to claim 13 , wherein

the control circuit board is housed in the grip part, the support part, or the battery holding part.

15 . A power tool comprising:

a motor;

a motor housing part that houses the motor;

a grip part that extends from the motor housing part;

a battery holding part to which a battery for supplying electric power to the motor is attached, the battery holding part and the grip part being formed as separate parts;

an elastic body that is sandwhiched between the grip part and the battery holding part to directly contact with the grip part and the battery holding part; and

a panel, which is disposed at a rear portion of the battery holding part and is manipulated to change a control method of the motor.

16 . The power tool according to claim 15 , further comprising

a light that is disposed at a front portion of the battery holding part.

17 . The power tool according to claim 15 , wherein

the panel faces a circuit board, and

a resin part holds the circuit board such that the circuit board is fixed to the battery holding part via the resin part.

18 . The power tool according to claim 17 , wherein

a surface of a motor control circuit board is inclined downward as the surface goes rearward.

19 . The power tool according to claim 15 , wherein

a motor control circuit board is housed in the battery holding part.

20 . The power tool according to claim 15 , wherein

a rear end of a motor control circuit board is positioned rearward of a rear end of the grip part.
