An operation input device includes an operation input unit that is configured to receive a tracing operation performed in a one-dimensional direction. The operation input unit includes a plurality of mechanical switches that are arranged side by side in an operation direction and each include an operation surface subjected to the tracing operation, the operation surface defining a curved surface along the operation direction.

Operation input device

A sign is provided capable of increasing strength. A sign includes plural symbol portions arrayed in an array direction. Blank regions with an enclosed shape, and blank regions with an opened shape opening in the array direction, are formed inside the symbol portions. Reinforcement portions are provided at the blank regions. The symbol portions are coupled together by coupling portions, and the coupling portions are provided such that an array width direction position of the coupling portions coincides with an array width direction position of the reinforcement portions.

A production method of a metallic decorative sheet () which is insert-molded integrally with a thermoplastic resin molded body () to constitute an insert molded body () has steps of: laminating a specular ink layer () on one surface of a transparent thermoplastic resin film () in a region except an edge region serving as an edge portion of the insert molded body () and in a region for displaying a metallic design on an outer surface of the insert molded body (), and laminating a non-specular ink layer () on the specular ink layer () and on the surface of the transparent thermoplastic resin film () where the specular ink layer () is not laminated.

Production method of metallic decorative sheet, and production method of insert molded body using the metallic decorative sheet

A manufacturing method of a film insert molded article in which no resin layer is seen in the front and no wrinkle is generated in a film is provided. A thermoformed film () for coating is arranged within a cavity (), and molten resin is injected so that a film insert molded article () molded integrally with the film () for coating and having a coating plane coated with the film () for coating is obtained. A printing ink layer () and a binder layer () are formed in a raw material film (). The raw material film () is cut out and the film () for coating is formed so as to have a size for coating the coating plane and being able to form an outer circumferential bending portion () arranged in an outer circumferential side portion () by adding a width exceeding a heat shrinking amount of the film. After the film () for coating is preheated, the film () for coating is thermoformed so that a predetermined three-dimensional shape () and the outer circumferential bending portion () are formed. The film () for coating in which the three-dimensional shape () and the outer circumferential bending portion () are formed, is arranged within the cavity () such that the binder layer () comes into contact with molten resin. The molten resin is then injected.

Manufacturing method of film insert molded article

In order to obtain a switch structure of a steering wheel in which a number of kinds of parts can be reduced and cost can be greatly reduced, there is provided a switch structure of a steering wheel at which a pair of opening portions symmetrically formed between an inner periphery of a rim of the steering wheel and an outer periphery of a pad cover as seen from a vehicle occupant side, at each of which opening portions a switch assembly formed by a plurality of switches is disposed, wherein arrangement and shape of the plurality of switches constituting the each switch assembly are determined so as to be symmetrical with respect to a predetermined base line intersecting the respective opening portions.
