Abstract
A guide bar for a motor chain saw has a guide bar member having a peripheral guide groove and peripheral shoulders for guiding a saw chain in the peripheral direction of the guide bar member. The drive members of the saw chain engage the guide groove and the lateral connecting members of the saw chain are guided on the shoulders. Wear protectors, made of a material that is more wear-resistant than the guide bar member, are provided. The wear protectors are connected to the peripheral shoulders so as to extend at least over a portion of the guide bar member in the peripheral direction. Each wear protector has a first wear surface facing the drive members of the saw chain and a second wear surface facing the lateral connecting members of the saw chain. At least one of the first and second wear surfaces of each wear protector has at least one peripheral recess extending in the peripheral direction.
