    • The object of the present invention is to propose a compressor in which rotation of a piston is prevented without affecting a big unbalanced load to the piston and the manufacture of the piston is simplified. The compressor comprises a housing having a cylinder bore therein, a drive shaft, a swash plate as a cam plate and a piston including a head portion and a neck portion. The housing and the piston are made of metal such as aluminium or an aluminium alloy. A rotation preventing member formed separately from the piston is mounted on the neck portion of the piston. The rotation preventing member is composed of a pair of rotation preventing portions, an abutting portion and a pair of caulking portions to mount to the neck portion. Those are made of metallic material such as iron series and formed in one body. The rotation preventing portion prevents the piston from rotating, cooperating with the contacting portion formed on the inner wall of the housing.
    • 本发明的目的是提出一种压缩机,其中防止活塞的旋转而不影响对活塞的大的不平衡载荷,并且活塞的制造被简化。压缩机包括其中具有气缸孔的壳体,驱动 轴,作为凸轮板的斜盘和包括头部和颈部的活塞。 壳体和活塞由铝或铝合金等金属制成。 与活塞分开形成的防旋转构件安装在活塞的颈部上。 防旋转部件由一对旋转防止部,抵接部和一对铆接部构成,能够安装在颈部。 它们由铁系列等金属材料制成,一体形成。 旋转防止部防止活塞旋转,与形成在壳体的内壁上的接触部配合。
