Provided are a rotating body (1), a brush cutter (9), and a bobbin (3) such that a linear cutter (8) can be used for a long period of time and the linear cutter (8) can be easily replaced when worn. The rotating body (1) is provided with a support case (2) and a bobbin (3). The support case (2) has a cylindrical section (21), a flange section (23) protruding from the cylindrical section (21), and a plurality of drawing holes (230) formed through the flange section (23). The inner circumferential surface (3A) of the bobbin (3) removably abuts the outer circumferential surface (21B) of the cylindrical section (21). A flexible linear cutter (8) is wound around the outer circumferential surface (3B) of the bobbin (3). Both end portions (81, 82) of the linear cutter (8) wound around the outer circumferential surface (3B) are pulled out to the outside in the radial direction through two drawing holes (230) among the plurality of drawing holes (230).

In order to obtain favorable cutting quality throughout a long-term, a rotating body has a brace that rotates integrally with a drive shaft of a mower, and a main body made of synthetic resin that is joined to the brace. The main body includes an upper body that is joined to the brace, a flange portion having a diameter larger than that of the upper body, a lower body having a diameter smaller than that of the flange portion, and an engaging structure with which the linear cutter is engaged. The upper body has, on the outer circumferential surface thereof, a plurality of outlets, from each of which one end of the linear cutter is pulled out. With the upper body integrally joined to the lower body with the flange portion therebetween, the linear cutter that is pulled out of each of the outlets is positioned above the flange portion.

　The present invention addresses the problem of using a linear cutter so that good cutting quality is obtained over a long period of time. [Solution] This rotating body is provided with a bracing which rotates integrally with the driving shaft of a mower, and a synthetic resin body section joined to the bracing. The body section is formed from an upper body joined to the bracing, a flange part having a larger diameter than that of the upper body, a lower body having a smaller diameter than that of the flange part, and an engaging structure with which the linear cutter is engaged. The upper body has, on the outer peripheral surface thereof, a plurality of lead-out ports through which one end side of the linear cutter is led out. In a state in which the upper body and the lower body are integrally joined so as to sandwich the flange part, the linear cutter led out from the lead-out ports is positioned above the flange part.

The present invention relates to a ground surface slide guide having a resin body made of synthetic resin, and a metal hub integrally coupled to the resin body to rotate together. The resin body is composed of a tubular body and a flange extending upward to the outside from the entire periphery of the lower end of the tubular body and covering the lower surface of the rotary blade. A blade retaining ring pressed against the lower surface of the rotary blade is formed on the outer periphery of the hub, and the blade retaining ring is exposed to the upper end surface of the tubular body. The hub is attached to a drive shaft by a fastener, and the rotary blade is clamped between a blade rest and a blade retaining ring. The lower end of the tubular body serves as a ground contact surface.

A large-diameter, lightweight, excellent-durability ground surface slide guide fixed to a lawn mower in order to perform mowing work comfortably. The ground surface slide guide comprises a resin body of synthetic resin, and a metallic hub coupled to rotate integrally with the resin body. The resin body is constituted of a tubular body and a flange extending upward externally from the entire periphery at the lower end of the tubular body to cover the lower surface of a rotary blade. A retaining ring being pressed against the lower surface of the rotary blade is formed on the outer circumferential part of the hub and exposed to the upper end face of the tubular body. The hub is fixed to a drive shaft by means of a fastener and the rotary blade is clamped between a blade rest and the retaining ring. Lower end portion of the tubular body works as a surface touching the ground. The metallic hub is coupled to rotate integrally with the resin body, overall weight is reduced by the resin body, lower surface of the rotary blade can be covered over a wide range, and stability to the ground surface can be enhanced. Furthermore, durability of the ground surface slide guide can be enhanced because wear resistance performance is enhanced by making the lower end portion of the tubular body working as a portion touching the ground surface thicker than the flange.
