Abstract
An injection molding machine includes first and second friction members, an expandable/retractable member provided in a periphery of the first and second friction members and including first and second end parts, a first attachment member attached to the first end part, and a second attachment member attached to the second end part. A lubricating oil is fed to an area between first and second friction members. A position of the second attachment member relative to the first attachment member is displaced in cooperation with a position of the second friction member relative to the first friction member. The expandable/retractable member is configured to form a reservoir space that stores the lubricating oil in the periphery of the first and second friction members. The expandable/retractable member is configured to expand/retract in correspondence with an interval between the first attachment member and the second attachment member.
