A polylactide-grafted cellulose nanofiber includes grafted cellulose having a graft chain bonding to cellulose constituting a cellulose nanofiber, wherein the graft chain is a polylactide, and a ratio of an absorbance derived from C&#x2550;O of the polylactide to an absorbance derived from O&#x2014;H of the cellulose on an infrared absorption spectrum is no less than 0.01 and no greater than 1,000. In addition, a production method of a polylactide-grafted cellulose nanofiber includes carrying out graft polymerization of a lactide to cellulose constituting a cellulose nanofiber in the presence of an organic polymerization catalyst which includes an amine and a salt obtained by reacting the amine with an acid.

Methods and devices for opening and closing a door of a drawer-type cooking device, enabling reduction in operation force by causing a drive mechanism not to put a load during an initial period when the door is opened or closed are provided. When a drawer body is driven by a drive mechanism including an electric motor to reach a stroke end such as a fully closed (opened) position, the drive mechanism is reversely driven only for a distance corresponding to a backlash existing in a transmission mechanism (between a pinion and a rack) and is stopped. When the drawer body is manually operated in the direction away from the stroke end, the drawer body moves without driving the drive mechanism against the inertia or load only for the distance corresponding to the backlash. As a result, the drawer body can start to be manually moved with a light burden.
