ABSTRACT:
A guide bar for a chain saw includes a first guide plate, a second guide plate and a spacer plate which is sandwiched between the first and second guide plates. Each of the first and second guide plates has a plurality of protrusions extending from an outer side thereof and recesses defined in an inner side thereof. A groove is defined along an outer periphery of the spacer plate and located between the first and second guide plates so as to receive the chain. The protrusions and recesses reinforce the structural strength of the guide bar and reduce the friction between the guide bar and the object to be cut.
