Abstract: A key cylinder device in which, in a locked state, a lock-releasing mechanism is provided so as not to operate even if a cylinder case swings. When a first lever rotates in a counterclockwise direction with respect to the cylinder case, a shaft provided on a second lever extends from a side surface of the second lever and engages with a third lever to move a rod attached to the third lever in a lock-releasing direction. Further, when the first lever does not move relatively with respect to the cylinder case, even if the cylinder case swings, the shaft does not extend from the side surface of the second lever and does not engage with the third lever. For this reason, there is no possibility that the rod attached to the third lever move in the lock-releasing direction.

Abstract: A plastic fastener for securing moldings to frames in vehicles. The fastener includes minor slots formed in the fastener and adjacent to a coupling structure. The minor slots provide sufficient flexibility to allow the fastener to flex inward under pressure, thereby permitting the coupling structure to move between an engagement position and a retracted position. The fastener is pushed through an opening in the frame. The opening is sized such that the edges of the opening apply pressure to the fastener as it moves through the opening, thereby moving the coupling structure toward its retracted position. When the fastener completely in the opening, the pressure is relieved, and the coupling structure snaps back to its engagement position, thereby engaging the edges of the opening and securing the fastener thereto. The fastener may be removed from the opening by applying sufficient pressure to again move the coupling structure to its retracted position.
