PROBLEM TO BE SOLVED: To easily actuate members other than a driver without applying a large moment to the driver.SOLUTION: An inside/outside pressure difference eliminating device comprises: an operating piece or an operating shaft provided in an operating member; and assisting means for assisting opening of a door by actuation of the operating piece or the operating shaft. Respective members composing the assisting means are all disposed in a lock case so as to cooperate with each other. A member on a side receiving input from the operating piece or the operating shaft is a driver performing linear movement or rotational movement. An output side member advancing from an opening/closing end of the door through a power conversion member from the driver is a short rod-shaped picking piece rotatably journaled in the vicinity of the back of a front of the lock case. When the door is opened, a tip of the short rod-shaped piece pressure contacts with a door frame side reaction member through the driver while rotating, and the pressure contact force works as a reaction force acting in a door opening direction. |
