Claims16
An impact tool, which performs a hammering operation on a workpiece by at least linear movement of a tool bit in an axial direction of the tool bit, comprising:
- a driving mechanism that drives the tool bit,
- an electric motor that drives the driving mechanism,
- an inner housing that houses the driving mechanism,
- an outer housing that houses the inner housing and the electric motor, and
- a covering member that covers an opening leading from outside to inside of the outer housing.
An impact tool, which performs a hammering operation on a workpiece by at least linear movement of a tool bit in an axial direction of the tool bit, comprising:
- a driving mechanism that drives the tool bit,
- an electric motor that drives the driving mechanism, and
- a housing that forms an outer shell of the impact tool, wherein:
- the housing has a first housing that houses the driving mechanism and a second housing that houses the electric motor,
- the first housing has a first contact region for contact with the second housing, and the second housing has a second contact region for contact with the first housing,
- the first contact region and the second contact region are relatively slidable relative to each other, and
- the first contact region and the second contact region are formed of different materials to each other.
