Japanese Patent JP4593387
Kind Code:
B2
Abstract:
It is an object of the invention to provide an effective technique for a motor support structure of a power tool to reduce vibration. A representative reciprocating power tool may include a tool body (103), a tool bit (119), a grip (109), a motor (111), a tool bit side bearing (151), a grip side bearing (153), a tool bit side bearing housing (152), and an elastic element (167). The tool bit side bearing housing (152) houses the tool bit side bearing (151), while the grip side bearing housing (157) houses the grip side bearing (153). The elastic element (165,167) is disposed between the grip side bearing housing (153) and the grip (109) wherein the grip side bearing housing (157) is elastically supported by the grip (109) via the elastic element (165,167). According to the invention, because the grip (109) is adapted to support the grip side bearing housing (157) via the elastic element (165,167) and the rigidity of the grip side bearing housing (157) can be increased and vibration of the grip side bearing housing (157) can be reduced. Further, the elastic element (165,167) can absorb manufacturing errors caused between the tool body (103) and the grip (109) when the grip (109) is mounted to the tool body (103).
