Cutting machine

Abstract

The present invention provides a cutting machine that cuts a structure by pressing a disk-shaped blade against the structure while rotating the blade, comprising: a machine body having wheels and rotatably supporting the blade; a motor for rotationally driving the blade; and a battery that stores electric power to be supplied to the motor, wherein the battery is arranged on an opposite side of the blade with respect to the motor in a width direction of the cutting machine.

What is claimed is: 
     
         1 . A cutting machine that cuts a structure by pressing a disk-shaped blade against the structure while rotating the blade, comprising:
 a machine body having wheels and rotatably supporting the blade;   a motor for rotationally driving the blade; and   a battery that stores electric power to be supplied to the motor,   wherein the battery is arranged on an opposite side of the blade with respect to the motor in a width direction of the cutting machine.   
     
     
         2 . The cutting machine according to  claim 1 , wherein the motor is arranged between the battery and the blade. 
     
     
         3 . The cutting machine according to  claim 1 , wherein the battery is configured to be attachable to and detachable from the machine body. 
     
     
         4 . The cutting machine according to  claim 1 , further comprising: a holder that has a connection terminal connected to a terminal of the battery and attachably and detachably holds the battery. 
     
     
         5 . The cutting machine according to  claim 3 , wherein the battery is arranged such that an upper end of the battery is positioned above an upper end of the blade in an up-and-down direction of the cutting machine. 
     
     
         6 . The cutting machine according to  claim 1 , wherein the battery is arranged such that the battery and the blade at least partially overlap each other in a side view of the cutting machine. 
     
     
         7 . The cutting machine according to  claim 6 , wherein the battery is arranged such that a front end of the battery is positioned behind a front end of the blade in a side view of the cutting machine. 
     
     
         8 . The cutting machine according to  claim 1 , wherein the battery is arranged such that a length of the battery in the width direction is shorter than a length of the battery in a front-and-rear direction of the cutting machine. 
     
     
         9 . The cutting machine according to  claim 1 , wherein a plurality of the batteries are provided in the cutting machine, and the plurality of batteries are arranged side by side in a front-and-rear direction of the cutting machine. 
     
     
         10 . The cutting machine according to  claim 1 , further comprising:
 a power control unit configured to control electric power to be supplied from the battery to the motor,   wherein the power control unit is arranged above the motor.   
     
     
         11 . The cutting machine according to  claim 1 , wherein the width direction is a direction parallel to a rotary shaft of the blade. 
     
     
         12 . The cutting machine according to  claim 1 , wherein the cutting machine is a hand push type work machine having a handle gripped by an operator.
