<P>PROBLEM TO BE SOLVED: To provide a cover-locking device provided with a locking part capable of suppressing maximum stress where elastic deformation part is deformed elastically low, while making the elastic deformation part compact. <P>SOLUTION: A cover 51 is provided freely openably by being turned about a bearing 51a. The lock 52 composed by having a locking projection 52a and the arcuate elastic deformation 52b is provided to the cover 51 integrally with the cover 51. By deforming the elastic deformation 52b, the locking projection 52a is locked to a locked part 55, or the locking of the locking projection 52a is released with the locked part 55. An arcuate shape forming the elastic deformation 52b is formed of a plurality of the circular arcs that differ in the curvature radius. According to this, the maximum stress in the elastic deformation 52b can be suppressed to be low, while making the projection dimensions of the elastic deformation 52b smaller. <P>COPYRIGHT: (C)2007,JPO&INPIT |
