Abstract: To reduce the size of a radio communication module installed in a vehicle by simplifying the structure thereof. A radio communication module 100 includes a board 170 on which electronic components 172 for radio communication are mounted and a housing 110 accommodating the board 170 and is installed in the vehicle. The board 170 has a hole 180 into which a pin 150 standing in the housing 110 is inserted to fix the board 170 in the housing 110 by inserting the pin 150 to the hole 180. The pin 150 functions as an antenna for transmitting and receiving a signal in the radio communication.

Abstract: A tarpaulin is held by one edge along one side of the truck body and is rolled on a longitudinally extending roller assembly so that when the roller assembly is rotated, the tarpaulin rolls across the top of the truck box transversely. Spring loaded check cables extend from the ends of the roller and are fastened to the truck body on the other side of the truck body to control the roller and tarpaulin as the roller is being rotated to cover and uncover the top of the box.
