1. A transmission mechanism comprising a housing, and a first rotating member that is accommodated in the housing and is rotatable about a first rotating member axis, the transmission mechanism further comprising a lubricating member that is accommodated in the housing and contains lubricant, wherein
the lubricating member comes into contact with a part of the first rotating member while applying a preload based on an elastic force during rotation of the first rotating member with respect to the lubricating member, thereby lubricating the part of the first rotating member with the lubricant, and
the lubricating member adsorbs dust from the first rotating member by contact with the first rotating member and adsorbs dust of which a particle size decreases according to a distance from a contact portion thereof with the first rotating member.
