Abstract: The invention provides an improved mechanical apparatus having a driving mechanism for moving two movably contacting members relative to each other. The driving mechanism is combined with a temperature-displacement converter which drives the two members to be displaced relative to each other in response to a variation of the environmental temperature independently of operation of the driving mechanism. The temperature-displacement converter provides a fine displacement of the movable contacts in response to a variation of the environmental temperature to prevent a possible adhesive phenomenon between the two members or a possible increase of the sliding resistance between them, thereby preventing an adhesive phenomenon between a magnetic head of the CSS type and a magnetic disk of a magnetic disk device and so forth.
