The front body structure of this type is, for example,
It is disclosed in Publication No. 1.

As shown in the same issue, with this type of body structure,
Generally, a lamp housing is placed between the left and right edges of a front panel to form a recess with an open front, and a headlamp, turn signal lamp, and car DJ light are housed in the recess.

By the way, headlamps and blinker lamps.

Bulbs used in vehicle side lights are usually life-threatening.
Before or after the end of its life, the filament will break and become unusable.

Furthermore, the filament may break due to vibrations caused by driving, etc., before reaching the end of its service life.

When a headlamp becomes unusable, it has to be replaced, but there is a particular problem that only exists in cab-over type cars, especially when replacing headlamp bulbs.

(Problem to be solved by the invention) Car headlamps are strictly set in the direction in which they illuminate the front when driving at night, so if the bulb burns out, replacing the entire headlamp will eliminate the illumination. Normally, only the internal valve is replaced because the direction etc. must be readjusted and the rotatability is affected.

However, in cab-over type cars, unlike normal bonnet type cars, there is no space on the back of the lamp housing for replacement work, and the back side is placed inside the conductor with a slight gap.

Therefore, if you are trying to replace a headlamp bulb,
This requires removing the floor mat inside the interior chamber and the cover panel that covers the opening formed in the lamp housing, and the work space is small because there are various engine peripheral equipment and seats on the back of the lamp housing. , the work from inside the conductor was extremely troublesome.

This invention was made in view of the above-mentioned conventional problems, and its purpose is to provide a cab-over type headlamp that allows headlamp bulbs to be easily replaced from outside the vehicle body without any troublesome work. The purpose is to provide a front body structure for a car.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a front body structure of a cab-over type vehicle, in which a lamp housing disposed between a front panel and a front pillar is connected to a lamp housing located between a front panel and a front pillar. The cross-sectional shape is formed to have a substantially oval shape, and includes a rear wall extending inward from the front edge of the rear wall, and a side wall extending from the inner end of the rear wall toward the front panel.

Further, a headlamp having a removably attached headlamp bulb is disposed in front of the rear wall of the lamp housing at a required distance from the rear wall.

Furthermore, between the headlamp and the front pillar,
A combination lamp that includes a turn signal lamp and a vehicle auxiliary light is installed to enable UJIR.

(Function) With the front body structure of a cab-over type vehicle configured as described above, if the lamp bulb of the headlamp is disconnected, ORIing the combination lamp will cause damage between the headlamp and the rear wall of the lamp housing. Since there is a work space in the area, you can easily replace the valve by inserting your hand into the space.
