The present invention relates to a cam for a bedding cleaner, which is made of polyketone and has excellent abrasion resistance, scratch resistance, and impact resistance. The cam for a bedding cleaner is fixated to a rotation shaft of a vibrator which vibrates a suction inlet port of the bedding cleaner, having a connecting rod linearly oscillate. The cam is manufactured from a polyketone copolymer comprising repeat unites represented by -(CH_2CH_2-CO)_x- and -(CH_2CH(CH_3)-CO)_y-. |
