The object of this invention is to provide a method for evaluating genetic ability for carcass weight in a bovine individual by using gene markers. According to the method, the nucleotide at the e9 site of the bovine NCAPG gene is determined. When it is G, genetic ability for increasing carcass weight is judged to be higher. Alternatively, the amino acid at the E9 site of the bovine NCAPG gene is determined. When it is methionine, genetic ability for increasing carcass weight is judged to be higher.

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.

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.

An electronic device is provided which is capable of reducing variations in the brightness of lights emitted from the light emitting parts. The electronic device has: a housing; a plurality of light sources provided within the housing, each light source emitting light along a light axis, the light axes of the light sources being directed in the same direction; and plurality of light guide plates provided within the housing, the light guide plates guiding the lights emitted from the light sources, respectively. Each light guide plate has a light incident plane on which the light emitted from the light source is incident and a light emitting part that is exposed at an outer surface of the housing. One of the light guide plates has a light incident plane angle that is different from the light incident plane angle of another light guide plate so that light axes of the lights that are guided within the light guide plates pass through the light emitting parts, wherein the light incident plane angle is an acute angle that is formed between the normal line of the light incident plane and the light axis of the light that is incident on the light incident plane.
