Actually, there's a reason why casters make noise, and with a little maintenance and ingenuity, you can make them surprisingly quiet.

This time, we'll clearly explain everything from "noise reduction measures" you can do at home right now to "how to choose a quiet suitcase" that you should check when you're looking to buy a new one.

一、スーツケースのキャスターがうるさい3つの原因

There is always a reason for how sounds are produced, and by identifying it, you can prevent unnecessary repairs and replacements.

When you notice the noise of the wheels of your suitcase, rather than just applying oil,
First, it is important to identify the cause .

There is always a reason for the way the sound is produced, and by identifying that reason you can prevent unnecessary repairs or replacements.

1. キャスターに髪の毛やゴミが絡まっている

The main reason is uneven ground. Especially on old asphalt or cobblestones, the vibrations from the wheels are transmitted to the body of the scooter, resulting in a loud noise. First, it's important to understand that the sound will change depending on the "quality of the ground."

2. キャスターの摩耗・破損や部品の緩み

If you feel that the noise has become louder than before, it may be because dust or hair has gotten tangled in the axle, or the lubrication has run out, causing friction. If the casters do not turn smoothly, a dragging noise will occur.

3. 路面の凹凸やキャスターの素材・構造

The surface of the caster (the rubber part) is a consumable item. After years of use, the surface can wear down and become wobbly, or harden and become unable to absorb shock. This is often the cause of unpleasant vibration noises.

二、スーツケースのキャスター音を軽減する3つの対策

Even if you're bothered by the noise from your casters, there's a simple sound-dampening maintenance you can try before sending them in for repair.

If the noise from your casters is bothering you, there are some simple noise reduction techniques you can try before sending your car in for repair.

No special tools are required and you can even do it with things you have at home.

1. キャスターの汚れや異物を取り除く

First, use tweezers or similar tools to remove any hair or dust tangled around the wheel axle. Then, simply spray a commercially available silicone spray onto the axle, and the friction will be reduced, making it surprisingly smooth and quiet.

Note: Some types of lubricants can damage rubber, so it is important to choose a "silicone-based" lubricant.

2. 摩耗・破損・緩みを確認する

Silicone caster covers have been gaining attention recently. Simply place them over the wheels like socks to absorb impacts from the ground and change the rattle sound into a soft "thump thump." Available at 100-yen shops, they kill two birds with one stone by also preventing dirt.

3. 移動する場所や走らせ方を見直す

If you tilt your suitcase and pull it on two wheels, the load on each wheel increases, making it more likely to make noise. On flat roads, try pushing the suitcase with the handles held vertically and all four wheels on the ground . This will distribute the vibrations and minimize the noise.

三、静かなスーツケースを選ぶときの3つのポイント

Three elements that greatly affect quietness (caster structure, material, and body type)

If your current suitcase has reached the end of its lifespan, why not choose your next one based on its quiet operation?

There are only three points you need to check.

1.キャスターの素材・構造を確認する

"Double casters," which have two wheels on a single leg, have a larger contact area with the ground, which helps to distribute shocks effectively.

Compared to single-type strollers, it rattles less and rolls smoothly and quietly even with heavy loads inside.

素材タイプ	特徴	静音レベル	耐久性
プラスチック（ABS）	安価で軽いが硬く、音が響きやすい	★☆☆	★★★
ゴム製	柔らかく静音性が高いが、摩耗しやすい	★★★	★★★
PU（ポリウレタン）製	適度な弾性と耐久性で最もバランスが良い	★★★★	★★★★

2. キャスターの品質や静音性能を確認する

Wheels with hard surfaces, like plastic, tend to produce a loud, jarring noise when hitting the ground. We recommend wheels made of soft, elastic materials such as rubber or PU (polyurethane) . These grip the ground like tires, resulting in significantly quieter operation.

3. 走行性能や本体重量もチェックする

If you're unsure which one to choose, look for models that use silent casters from reliable manufacturers such as Hinomoto (Hinomoto Locks) . These casters, which minimize friction noise with their unique technology, offer such comfort that you won't want to go back to your old model once you've used them. The entire body is made of resin, which has the added benefit of softly absorbing shocks from the ground.

・In other words, the key to quietness is not the structure, but :

Caster material (elastic material such as PU or rubber)
Caster installation angle and bearing accuracy
Body rigidity balance
