Claims

[Scope of utility model registration request]

In a twin-wheel caster, in which an axle for supporting wheels on both sides is horizontally supported on a swinging main body, and a vertical shaft extending in a direction orthogonal to the axle at an eccentric position is rotatably supported on the swinging main body, in a recess of the swinging main body. It consists of a wheel stopper member that is elastically supported so that its protrusions on both sides face the engagement grooves on the inner periphery of each wheel, and an operating lever that engages the tip cam surface with the wheel stopper member and is pivotally supported on the above-mentioned turning main body. In addition to providing a wheel stop means, a rotation stopper member is inserted into and elastically supported in a hole of the swing main body so as to be releasably connected to the lower end of the vertical shaft, and the swing stop member is pushed and biased by a tip cam surface. A swing stop means is provided which includes a control lever pivotally supported on the main body, and each control lever of these stop means is aligned with the vertical axis of the swing main body and is arranged to be selectively swingable up and down, and A twin-wheel caster characterized in that both operating positions are set to be in a locked state.
