A keyboard includes a main body and a support for adjusting the angle of the main body. The bottom of the main body defines slots, and furrows defined in opposite side walls of the slots. The support is accommodated in the main body, includes brackets received in the slots, two shafts, two driving portions, and two elastic pieces. The shafts slide relative to the main body. The driving portions are received in the shafts and are flexible relative to the shafts. One end of each elastic piece is fixed to the sidewall of each shaft, the other end resists one of the driving portions. When one of the shafts is moved, the shaft drives the elastic pieces to support the driving portions, one end of each driving portion is pushed out of the shaft to prop up the bracket. |
