Abstract
Each of a pair of chopsticks has a case made of a synthetic resin, having an open front end, and a food holding member made of wood or bamboo, housed in the case slidably between its retracted and extended positions through the front end of the case. The holding member is greater in length than the case. The case has at least two diametrically opposed projections formed on its inner surface adjacent to its front end, and has therebetween a distance which is smaller than the diameter of the holding member in its inner end portion. The case also has at least one protruding wall portion formed on its inner surface inwardly of the projections, giving the case an inside diameter which is slightly smaller than the diameter of the holding member in its inner end portion. The holding member has an annular groove formed in its peripheral surface at its inner end portion, and the projections engage the groove when the holding member is in the extended position.
