Mr Chuvit was walking to the polling station from his home in Soi Ratchadapisek 3 when a man dressed in black and with a whistle bearing the colours of the national flag charged at him, striking him on the left side of his head.
The man, believed to be an anti-government protester, was immediately apprehended by Mr Chuvit's guards. He suffered a head injury and then fled on a motorcycle.
Mr Chuvit reportedly said that he would not file a police complaint or hold any grudge against the man, adding that he only cared about exercising his right to vote.
He said protesters are wrong to obstruct other people from voting, and asked the media to convey his message to People's Democratic Reform Committee leader Suthep Thaugsuban.
Those who do not like the government can simply tick the "no vote" box, he said.
