Patent number: 7603881Abstract: In a glove box device, a cylinder is fixed to an operating handle, a slide member switches between a locking state and an unlocking state in correspondence to sliding motion, and a connecting member is interposed between one end of the slide member and a rotor. The connecting member transmits a turning force of the rotor turning along with the operating handle to the slide member, to move the slide member from a locking position to an unlocking position when the rotor is in the unlocking position. The connecting member cuts off the transmission of turning force between the slide member in the locking position and the rotor, when the rotor is in the locking position. Thus, it is possible to reduce the number of components needed, and also to reduce a gap between a design face of the operating handle and the cylinder lock, thereby improving the appearance.Type: GrantFiled: October 12, 2006Date of Patent: October 20, 2009Assignee: Kabushiki Kaisha Honda LockInventors: Jin Yukihara, Takuya Miyagawa
