MITER SAW

摘要

A miter saw (1) has a base unit (10), a cutting unit (30), and a supporting unit (40). The base unit (10) supports a workpiece. The cutting unit (30) has a rotary cutting blade (31) having two side faces, a motor (33) for driving the rotary cutting blade (31), and a housing (30A) having a blade cover (300A) for covering a part of the cutting blade (31) and a motor housing (300B) provided to the blade cover (300A) on one side face of the rotary cutting blade (31) for accommodating the motor (33). The supporting unit (40) is supported to the base unit (10) for pivotably supporting the cutting unit (30). The supporting unit (40) is configured to move the cutting unit (30) toward and away from the base unit (10) in a first direction. The support unit (40) has a guide unit (50,51) supported to the base unit (10), and a sliding unit (36) having a pivot shaft (32) pivotably supporting the cutting unit (30). The guide unit (50,51) extends parallel to a second direction and having a front end. The sliding unit (36) is guided by the guide unit (50,51) to move between a front position and a rear position in the second direction. The pivot shaft (32) extends in a third direction perpendicular to the first and second directions. The motor housing (300B) has a proximal end to the rotary cutting blade (31) and a distal end in the third direction. At least one part of the guide unit (50,51) is positioned on the one side face and between the cutting blade (31) and the distal end in the third direction. When the sliding unit (36) is positioned at the rear position, a first distance between the pivot shaft (32) and a closest point of the motor housing (300B) to the pivot shaft (32) in a plane extending in the first direction and containing the guide unit (50,51) is longer than a second distance between the pivot shaft (32) and the front end of the guide unit (50,51) in the plane.
