It is indispensable to use a vinyl chloride resin containing 1% by weight and a balance of THF-soluble components. A vinyl chloride resin containing a crosslinked gel component is a mixture of vinyl chloride and a polyfunctional monomer copolymerizable thereto, or, if necessary, together with another monomer copolymerizable with vinyl chloride.

Adjust to the desired content. By setting the crosslinked gel content of the vinyl chloride resin in the range of 2 to 50% by weight, matting can be performed without lowering the physical strength of the molded vehicle interior part, and the vehicle interior part is excellent in design. Becomes 2
Less than 50% by weight has less matting effect and less than 50% by weight

Then, it is desirable that 60% by weight or more, preferably 80% by weight or more, and particularly 95% by weight or more of the plasticizer is a plasticizer having a molecular weight of 410 or more. If the content of the plasticizer having a molecular weight of 410 or more is less than 30 parts by weight, a sufficient plasticizing effect cannot be obtained, and if it exceeds 150 parts by weight, problems such as bleeding of the plasticizer occur.

It is essential that the vinyl chloride resin composition for molding vehicle interior parts of the present invention contains an antibacterial agent.
Any antibacterial agent may be used as long as it can be mixed with the vinyl chloride resin, but usually, a commercially available antibacterial agent is used as it is. Antibacterial agents are broadly classified into organic compound antibacterial agents and silver-based antibacterial agents in which silver ions are supported on inorganic compounds. However, considering the persistence of antibacterial performance and low toxicity to the human body, silver-based antibacterial agents are considered. It is desirable to use an agent. The content of the antibacterial agent varies depending on the type and components of the commercially available antibacterial agent, but is in the range of 0.01 to 5 parts by weight based on 100 parts by weight of the vinyl chloride resin. If the content is less than 0.01 part by weight, the antibacterial effect is hardly exhibited, and if added in excess of 5 parts by weight, no remarkable increase in the antibacterial effect is observed, which is economically disadvantageous.

A filler can be added to the vinyl chloride resin composition for molding vehicle interior parts of the present invention. The addition of the filler is not only economically advantageous but also absorbs an excessive amount of the plasticizer to facilitate the kneading operation, and has a matting effect as described above. However, if a large amount of filler is added, the weight reduction is impaired and the scratch resistance tends to be poor. Therefore, the addition amount should be limited to 60 parts by weight with respect to 100 parts by weight of the vinyl chloride resin. As a filler,
