The invention discloses a trundle with a damping function. The trundle comprises a fixed base, a clamping base, a clamping rod, a wheel base, a damping device and two wheels. The rear end of the clamping base is connected with the fixed base in a relatively rotatable manner through the clamping rod; a first hollow structure penetrating through the upper end and the lower end of the clamping base is arranged at the front end of the clamping base. The lower end of the wheel base is connected with the two wheels through a rotating shaft, the upper end of the wheel base is slidably inserted into the first hollow structure, and a second hollow structure with an opening in the upper end is arranged at the upper end of the wheel base; the damping device comprises an upper clamping piece, a lowerclamping piece and an elastomer. The elastomer is made of rubber or TPE; the elastomer is mounted in the second hollow structure; the upper end of the elastomer is fixedly connected to the upper end of the wheel base through the upper clamping piece, the lower end of the elastomer is connected to the wheel base through the lower clamping piece, strip-shaped sliding holes corresponding to the lowerclamping piece are formed in the left side and the right side of the wheel base, and the two ends of the lower clamping piece correspondingly penetrate through the two strip-shaped sliding holes andthen are fixedly connected with the clamping base. The trundle is good in damping effect.
