Document Type and Number:
Japanese Patent JP7463249
Kind Code:
B2
Abstract:
To provide a toilet lid device capable of reducing a gap between a toilet lid and a casing when the toilet lid is closed as much as possible while inhibiting the toilet lid from interfering with the casing when the toilet lid is rotated even in the case where an arm hinge structure is adopted.SOLUTION: A toilet lid device includes a casing, a toilet lid, and an electric opening/closing device. The electric opening/closing device includes a drive part, a rotation part, a transmission part, and a storage part. The rotation part includes a pinion part, and the transmission part includes an arm part having a rack part that meshes with the pinion part, and a protrusion part that protrudes from the arm part. The storage part includes a rail part where the protrusion part can slide in a front-back direction. The rotation part causes the rack part to slide forward by the pinion part when rotating in an opening direction of the toilet lid, and causes the toilet lid to slide forward together with the transmission part by the protrusion part sliding forward in the rail part. The transmission part causes the toilet lid to rotate in an opening direction by rotating from a position that it has slid forward together with the storage part.SELECTED DRAWING: Figure 4
