1. An engaging mechanism comprising:
an engaging member provided to a first member; and an engaged member provided to a second member, wherein: the engaging member and the engaged member are freely detachably engageable with each other when the first member is moved relative to the second member in a predetermined direction; the engaging member includes an engaging main part extending in the predetermined direction from the first member and an engaging claw part formed on a distal end of the engaging main part, the engaging main part and the engaging claw part being resiliently deformable, the engaging claw part having a concave curved engaging surface defined by a first continuously changing radius of curvature; a convex curved engaged surface defined by a second continuously changing radius of curvature; the convex curved engaged surface of the engaged member being received in the concave curved surface of the engaging surface of the engaging member, the engaging surface of the engaging claw part contacts the engaged surface of the engaged part at a linear contact area at a time from when the engaging claw part and the engaged part are in engagement with each other through to when the engaging claw part is disengaged from the engaged part wherein upon disengagement of the engaging claw part and the engaged part, the engaging member resiliently deforms away from the engaged member; and a curvature of the engaging surface at the linear contact area is smaller than another curvature of the engaged surface at the linear contact area. |
