An electronic device including a first body, a second body, and a linking-up member is provided. The second body connected to the first body is capable of being opened and closed relative to the first body. The second body has a first and second restriction member. The linking-up member is assembled to the first body. Two opposite ends of the linking-up member is coupled to the first restriction member and the second restriction member respectively, where the first restriction member provides a first stroke and the second restriction member provides a second stroke to the linking-up member. One of the first stroke and the second stroke is a linear path and another one is a curved path. When the first body is expanded relative to the second body, the liking-up member combines the first stroke and the second stroke to drive the second body rotating relative to the first body.
