Patent ID: 8813377

Claim:
A reciprocating cutting tool comprising: a body housing; an electric motor; and a motion converting mechanism configured to convert rotation of the electric motor into a reciprocating motion of a rod having a blade mounted thereon, wherein: the electric motor and the motion converting mechanism are disposed within the body housing, the motion converting mechanism includes a crank disk configured to be rotated by the electric motor, a guide member eccentrically mounted to the crank disk and configured to make an orbital motion by the rotation of the crank disk, and a slider capable of reciprocating in a reciprocating direction of the rod and configured to transmit to the rod a component of the orbital motion of the guide member in the reciprocating direction to cause the reciprocating motion of the rod, the slider has a flat plate shape and includes a guide plate portion and a support plate portion; the guide plate portion has a guide groove portion engaging the guide member; the support plate portion extends in the reciprocating direction of the rod, the guide plate portion is held from opposite sides in a direction of thickness of the flat plate shape by a flange portion provided on the guide member and a support plate mounted on the body housing, so that the guide plate portion is prevented from moving in the direction of thickness; and the support plate portion is inserted into a support hole formed in a slider guide provided in the body housing, so that the support plate portion is prevented from moving in a direction perpendicular to a plane of the support plate portion.
