PURPOSE: To provide a guide device of a keyboard by which applying work of a lubricant can be very efficiently performed and a part between the keyboard and a guide material can be reliably lubricated without wastefully consuming the lubricant and without staining the keyboard with the lubricant. CONSTITUTION: In a guide device of a keyboard whose under side is opened and which has a pair of mutually opposing side walls 1b and 1b and is rotatably supported with a keyboard chassis 2 and guides a keyboard 1 whose limit push- key position is regulated by coming into contact with a stopper cushion 8 composed of an elastic material, the device is provided with a guide material 12 which has two side surfaces and is arranged on the keyboard chassis 2 in a standing-up condition and where the keyboard 1 is embedded in the two side surfaces so that a pair of side walls 1b and 1b of the keyboard 1 are respectively opposed to each other, and a pair of lubricant receiving pieces 14 and 14 which can receive a lubricant and define a lubricant receiver 14 communicated with the side surfaces of the guide material 12 between mutual ones, are formed in an upper end part of this guide material 12. |
