<p>PROBLEM TO BE SOLVED: To be easily adaptive to a change in a direction of portable equipment while attaining stable one-hand holding in simple configuration.SOLUTION: On a back part 2a of a hold cover case 2 which can be mounted to a smartphone S from its back side, first and second finger holes 3 and 4 are opened while holding an elongation/contraction band body 5 which forms a portion of the back part 2a and is elastically deformable, therebetween. A finger F can be inserted from a lateral side of the hold cover case 2 into the finger holes 3 and 4. An edge of a side of the first finger hole 3 closer to the elongation/contraction band body 5 is an edge of one side of the elongation/contraction band body, and an edge of a side of the second finger hole 4 closer to the elongation/contraction body is an another edge of the elongation/contraction band body. Sides of the finger holes closer to the elongation/contraction body 5 are arcuate sides 3b and 4b which are expanded oppositely to each other.</p> |
