Office Chair Parts: Japanese Translations

The Japanese expressions for office chair parts are as follows:

1. Gas Lift Cylinder: Known as 「油圧式シリンダー」 in Japanese. This is the core component for the height adjustment function of office chairs, regulating seat height through hydraulic principles. The term 「油圧式」 clearly indicates the hydraulic drive method, while 「シリンダー」 is the general translation for 'cylinder' or 'hydraulic cylinder'.

2. Footrest: Written as 「足置き」 in Japanese. This part is typically used to support the legs, alleviating fatigue from prolonged sitting, and is commonly found in high-end office chairs or lounge chairs. The term 「足」 corresponds to 'foot', and 「置き」 means 'placement' or 'support', directly translating to 'foot placement'.

3. Casters/Wheel Parts: Uniformly referred to as 「キャスター」 in Japanese. This is the key component for the mobility function of office chairs, usually consisting of wheels, brackets, and bearings. The term 「キャスター」 originates from the English word 'caster' and is directly borrowed into Japanese as a general term applicable to all wheeled mobile devices.

4. Chair with Wheels at the Base: Known as 「キャスターチェア」 in Japanese. This is a complete description of an office chair with wheels, where 「キャスター」 refers to the wheel part, and 「チェア」 is the transliteration of 'chair'. This term is commonly used in product descriptions or classifications.

5. Adjustable Armrests: Expressed in Japanese as 「肘かけ（高さ调节机能付き）」 or 「○○椅子肘付き（高さ调节可能）」. The former emphasizes that the armrest itself has a height adjustment function, with 「肘かけ」 meaning 'armrest' and the parentheses providing supplementary information about the function; the latter is used for specific product models, with 「肘付き」 indicating 'with armrests' and 「高さ调节可能」 clearly stating that the height is adjustable.

6. Armrest: Simply called 「肘かけ」 in Japanese. This is one of the most basic components of an office chair, used to support the arms and reduce shoulder and neck strain. The term 「肘」 corresponds to 'elbow', and 「かけ」 means 'support' or 'placement', directly translating to 'elbow support'.

These terms are widely used in the office furniture industry, product manuals, or Japanese business contexts. Mastering these expressions facilitates more precise communication or reference to relevant materials.
