In a state where the body is connected with a locking part and attached to a user, the central axis of the locking part in the length direction and the central axis of the body in the length direction form a predetermined angle at the connection of the locking part and the body. The central axis of the body inclines farther to the user side than the central axis of the locking part, with the abutting portion of the locking part against the temple as a starting point. !
