PROBLEM TO BE SOLVED: To solve a problem of an unfixed shape of a rubber glove which requires an assist tool to apply a force to widely open for wearing.SOLUTION: An insertion opening width adjusting mechanism 40 is provided at an opening end of a housing 30, the opening end being formed in an elliptical shape by a slider 41 and an extension 42. The extension 42 is slidably provided to the fixed slider 41 so as to provide a small-diameter state of a small opening width and a wide-diameter state of a wide opening width. First, an insertion opening of a rubber glove is set to the small-diameter state, and then the extension 42 is slid to provide the wide-diameter state. Thus, the insertion opening of the rubber glove can be stably opened by the extension 42 without requiring an additional force.SELECTED DRAWING: Figure 1
