The disclosure relates to a target assembly of the type for use in a target practice range. The target assembly includes a base, a motor in the base, a first rotatable member coupled to the motor, a second rotatable member and a pivotable target member coupled to the second rotatable member. The first rotatable member includes an extension which engages a radial slot within the second member during rotation to cause the second rotatable member to rotate for raising and lowering the target member. The first and second rotatable members have cooperating cam surfaces for locking the target member in a vertical and horizontal position and for freeing the rotatable members for rotation during the raising and lowering of the target member.
