An arm rest attachable to a seat for a vehicle occupant to sit on includes a pair of side members, a front member, and an airbag. The pair of side members are configured to be at left and right sides of the vehicle occupant when the vehicle occupant is seated. The side members extend in a front-rear direction and are coupled to the seat. The front member is configured to be in front of the vehicle occupant when the vehicle occupant is seated and is coupled to at least one of the pair of side members. The airbag is configured to deploy toward the vehicle occupant from the front member. When the vehicle occupant comes into contact with the deployed airbag, the airbag is supported by a reactive-force member from which a reactive force is obtained as a result of the airbag abutting on the reactive-force member.
