Abstract
A wheel for a baby walking cart has wheel parts fitted to two sides of a support member with an axle being passed through the central holes of the wheel parts and an elongated hole of the support member. The axle is also passed through a tubular slide member, which is movably received in the elongated hole, and biased towards a front end of the elongated hole by an elastic member. The wheel members have wavy slowing-down portions on inner circular surfaces. The elastic member acts against a force caused by the forward movement of the cart to push the wheel members towards the rear end of the elongated hole for keeping the wavy portions off slowing-down rods of the support member when the cart is moved along. When the cart is moved along too fast, the wheel members are forced to move towards the rear end of the elongated hole for the wavy portions to contact the slowing-down rods to slow down the cart.
