The invention provides a roller wheel for a caterpillar type driving vehicle. The roller wheel has a simplified structure and is easy to maintain and inspect. The roller wheel is configured such that: the roller wheel is provided with a wheel body (52) which has an entrance side which is inserted with an axle (53) which has a middle large-diameter part (65). The entrance side is provided with an inner diameter which can be inserted to the middle large-diameter part (65). The wheel body (52) is also provided with an exit side which enables a top end side of the axle (53) which is inserted therein to protrude. The exit side is provided with an inner diameter which is smaller than an outer diameter of the middle large-diameter part (65). On the exit side, the external circumference of an O-shaped ring (71) of a floating oil seal (61) abuts against the wheel body (52). At the entrance side, the external circumference of the O-shaped ring (71) of the floating oil seal (61) abuts against an internal barrel (58).
