    Abstract: A dust collection nozzle extends from the front of a fixing cover parallel to a base below an upper end of an electric motor. Heavy and large cutting dust can be immediately collected from an area relatively close to a cutting position of a portable cutting device cutting a workpiece immediately after dust is generated due to the cutting, which can in turn improve dust collection efficiency of a dust collection device to which the dust collection nozzle is attached.

    Abstract: A portable machining apparatus has high operability in tilting a body with respect to a base or in machining a workpiece with the tilting body. A portable machining apparatus placeable on a long gauge placed on an upper surface of a workpiece includes a base placeable on the long gauge, a body including a blade for machining the workpiece, an angular plate fixed to the base to support the body in a tiltable manner and including a protrusion, a body support located between the body and the base and including a guide engageable with the protrusion to allow sliding of the protrusion on the guide, and a spring that urges the protrusion toward the guide.

    Abstract: A wind shielding portion is provided in a front side of an exhaust port for cooling air from a motor such that it crosses over a lateral width with respect to a cutting direction. The cooling air which is blown to the wind shielding portion is effectively blown through a ventilation portion having a small ventilating resistance force and towards a marking line guide. Even when the cutting device main body is set at an incline, the cooling air is blown to the wind shielding portion, and is effectively blown through the ventilation portion to the marking line guide.

    Abstract translation: 风挡屏蔽部分设置在排气口的前侧，用于冷却来自电动机的空气，使得其相对于切割方向跨越横向宽度。 被吹送到挡风部的冷却空气通过具有小的通风阻力的通气部分朝向标记线引导件被有效地吹送。 即使当切割装置主体设置为倾斜时，冷却空气也被吹送到挡风部分，并且有效地通过通风部分吹送到标记线引导件。
