Abstract

A jigsaw includes a jigsaw main body, a handle, and a battery. The jigsaw main body includes a housing, a motor disposed inside the housing, and a battery mounting portion having a first mounting surface facing downward. The handle is disposed at an upper portion of the jigsaw main body and above the motor. The battery has a second mounting surface and supplies the motor with an electric power. The battery is slidable along the first mounting surface and mountable to the battery mounting portion with the first and second mounting surfaces facing each other.

First claim

What is claimed is:

1. A jigsaw comprising:
a jigsaw main body including,
a housing,
a motor disposed inside the housing, and
a battery mounting portion having a first mounting surface facing downward;

a handle disposed at an upper portion of the jigsaw main body and above the motor; and
a battery having a second mounting surface, the battery configured to supply the motor with an electric power, the battery being slidable along the first mounting surface, the battery being mountable to the battery mounting portion with the first and second mounting surfaces facing each other;
wherein the battery is mountable to the battery mounting portion such that the battery overlaps with the motor in a front view.

2. The jigsaw according to claim 1 , wherein
the battery is mountable to the battery mounting portion such that the battery overlaps with the handle in a top view.

3. The jigsaw according to claim 1 , further comprising
a plate-shaped controller configured to control the motor, the controller being disposed above the battery and being along the second mounting surface.

4. The jigsaw according to claim 2 , further comprising
a plate-shaped controller configured to control the motor, the controller being disposed above the battery and being along the second mounting surface.

5. The jigsaw according to claim 3 , wherein
the controller is arranged such that the controller overlaps with the handle in a top view.

6. The jigsaw according to claim 4 , wherein
the controller is arranged such that the controller overlaps with the handle in a top view.

7. The jigsaw according to claim 1 , further comprising:
a centrifugal fan disposed inside the housing;
a cooling air intake port disposed at a rear part at the housing with respect to the motor, the cooling air intake port being configured to cool the motor; and
a controller configured to control the motor, the controller being disposed along an imaginary straight line passing through the centrifugal fan and the cooling air intake port.

8. The jigsaw according to claim 1 , further comprising:
a dust suction adapter coupled to a hose for a dust collection device, the dust suction adapter being detachably attached below the battery;
wherein the battery is disposed at a rear of the motor.

9. The jigsaw according to claim 8 , wherein
the dust suction adapter includes,
a front portion,
a rear portion located below the front portion, and
a bent portion connecting the front portion and the rear portion.

10. The jigsaw according to claim 8 , further comprising:
a fastening member having a conductive property and disposed inside the housing; and
a base connected to the housing at a lower side of the housing with the fastening member;
wherein the dust suction adapter is mountable such that the dust suction adapter contacts the fastening member.

11. The jigsaw according to claim 1 , wherein:
the battery is disposed at the rear of the motor; and
the battery is mountable to the battery mounting portion by sliding in a front-rear direction.

12. The jigsaw according to claim 1 , further comprising:
a controller configured to control the motor, the controller including a switching element;
wherein the motor is a brushless motor including,
a stator having a plurality of coils, and
a rotor,

wherein the switching element switches an electric power supply to the plurality of coils.

13. A jigsaw comprising:
a jigsaw main body including:
a housing;
a motor disposed inside the housing; and
a battery mounting portion having a first mounting surface facing downward;

a handle disposed at an upper portion of the jigsaw main body and above the motor;
a battery having a second mounting surface, the battery configured to supply the motor with an electric power, the battery being slidable along the first mounting surface, the battery being mountable to the battery mounting portion with the first and second mounting surfaces facing each other; and
a plate-shaped controller configured to control the motor, the controller being disposed above the battery and being along the second mounting surface.

14. A jigsaw comprising:
a jigsaw main body including:
a housing;
a motor disposed inside the housing; and
a battery mounting portion having a first mounting surface facing downward;

a handle disposed at an upper portion of the jigsaw main body and above the motor;
a battery having a second mounting surface, the battery configured to supply the motor with an electric power, the battery being slidable along the first mounting surface, the battery being mountable to the battery mounting portion with the first and second mounting surfaces facing each other;
a dust suction adapter coupled to a hose for a dust collection device, the dust suction adapter being detachably attached below the battery;
a fastening member having a conductive property and disposed inside the housing; and
a base connected to the housing at a lower side of the housing with the fastening member; wherein:
the battery is disposed at a rear of the motor; and
the dust suction adapter is mountable such that the dust suction adapter contacts the fastening member.
