A sport playing equipment capable of changing the maximum rotation angle of a foot rest includes a body; a steering shaft rotatably engaged to the body and extending upwardly from the ground, the steering shaft being provided with a wheel at the lower end and a handle portion at the upper end; and a pair of foot rest members engaged to the body and extending in parallel with the ground, each foot rest member having a wheel at the rear end. The foot rest members are engaged to be able to rotate in left and right directions of the body. A symmetrically rotating member is disposed at the front end of each foot rest member, and is rotatably coupled to the rotation shaft fixed to the body, so that the foot rest members are symmetrically moved by the symmetrically rotating members. The symmetrically rotating member has a rotation restricting portion of a three-dimensional shape which protrudes outwardly from the cross section perpendicular to the rotation shaft in a radial direction of the symmetrically rotating member and extends towards the rotation shaft. A maximum rotation angle changing member is interposed between the rotation restricting portions of the symmetrically rotating members to restrict the distance between the rotation restricting portions, thereby changing the maximum rotation angle of the foot rest members. The maximum rotation angle changing member has a first stopper coming into contact with the rotation restricting portion, and a second stopper disposed in a direction different from the first stopper and having a length or thickness different from that of the stopper. |
