Abstract: Disclosed is a variable-diameter wheel including a wheel having a folding pattern in which a unit cell is repeated and configured to be expanded or contracted so that a wheel diameter is varied; a spoke fixedly coupled to both longitudinal ends of the wheel and configured to be expanded or contracted according to a change in a distance between both sides, such that the wheel diameter is varied; and a variable induction shaft rotatably coupled with one of the both spokes to move the spoke in at least one lengthwise direction and configured to vary a distance between one spoke and the other spoke.

Abstract: The pen holder includes a first, second and third cover portions, a connecting part and a fixing unit. The first, second and third cover portions are respectively inserted into a thumb, a forefinger and a middle finger. The connecting part connects the first, second and third cover portions. A first end of the connecting part is fixed to one of the first, second and third cover portions. A force is applied to a second end of the connecting part such that the first, second and third cover portions are closed to each other. A fixing unit fixes to the second end of the connecting part and applies the force to the connecting part.
