A fastening assistance structure has a bolt hole for passing therethrough a threaded portion of a bolt, a seat face for engaging a head seat face of the bolt, and a partition wall for guiding the bolt into the bolt hole. A bolt inlet which is open at an end of the partition wall lies flush with an end face of a bulge. Even when the bolt hole is positioned behind the bulge, the bolt inlet can be seen, and the bolt can be inserted from the bolt inlet into the partition wall. If the partition wall has an inner wall of a tapered shape progressively smaller in diameter toward the bolt hole, then the bolt can easily be inserted along the inner wall of the partition wall into the bolt hole.

In a vehicle air conditioner, a link mechanism, for connecting one of plural driving devices and one of plural air mixing doors to each other is connected to a hot water valve, and is constructed to be operated to first and second maximum cooling positions. At the first maximum cooling position, the one door connected to the link mechanism is operated to a door maximum cooling position, and the valve is opened. At the second position, the door connected to the link mechanism is operated to the door maximum cooling position, and the valve is closed. Therefore, the valve can be suitably opened and closed in accordance with operation positions of the plural air mixing doors without using a dedicated driving mechanism for the valve.

A surface, which receives shocks when hit by a radio unit upon a vehicle collision, has grooves defined in a peripheral region thereof. The surface also has a protrusion in a region, which can possibly be hit by the radio unit. Upon a vehicle collision, a rear surface of the radio unit initially impinges upon the protrusion. Stresses are concentrated on the protrusion, developing a crack in a groove near the protrusion. Once the crack is developed, it easily spreads along the groove.
