Problems solved by technology

[0012] However, although the invention disclosed in Document 1 improves the current problem relatively well, there is still room for improvement in the sound when the spring guide 57 touches the parts arranged inside it.
Furthermore, as described above, the spring guide 57 disclosed in this document 1 exhibits vibration damping performance through a combined structure with the elastic ring 62 incorporated in the seat itself, so the shape of the seat itself is complicated and the assembly is not easy. issues that should be resolved

Abstract

The invention provides a spring guide and a cushion device with good absorption characteristic capable of effectively suppressing the resonance vibration of a coil spring in the cushion device and effectively preventing the vibration generated by the noise of the coil spring. The approximately cylindrical spring guide is arranged between the coil spring and an outer shaft member. The coil spring houses a shaft portion of a damper set and arranged between the outer shaft member and an inner shaft member. In the damper set, the inner shaft member is fitted in the cylindrical outer shaft member slidably in an axial direction of the spring guide. Projecting portions projecting towards the shaft core direction are arranged on one end and another end of a main body . The invention also provided the cushion device with the spring guide. The vibration of the coil spring is effectively suppressed.

Description

technical field [0001] The present invention relates to a spring guide that guides a coil spring that suspends a wheel of a vehicle, and a shock absorber unit including the spring guide. Background technique [0002] Vehicles such as motorcycles and carts have cushioning units for suspending their wheels. This cushioning unit has a function of appropriately cushioning up and down movements accompanying the running of the vehicle. For example, in a two-wheeled motor vehicle, a rotatable rear wheel is supported on a rocker arm, and the rocker arm is provided on the vehicle frame to swing up and down freely, and a buffer unit is arranged between the rocker arm and the frame The up and down movement of the moving rear wheels is cushioned to maintain maneuverability and ride comfort. [0003] The structure of this buffer unit includes: a damper device in which the inner shaft member is slidably fitted in the cylindrical outer shaft member in the axial direction; Coil spring be...
