いる（特開昭５８−９１２５５号参照）。Therefore, conventionally, a reinforcing sheet made of cloth, paper or the like is adhered with an adhesive so as to cover the entire one surface of a veneer stripped by a rotary lace from an arbitrary raw wood, and this is stripped with a slitter to have an appropriate width. As a veneer, a wooden tubular body formed by spirally winding a plurality of band-shaped veneers around a mandrel so that the twist directions of all the band-shaped veneers are the same has been used. (See JP-A-58-91255).

度が大きく相違しない。[Function] A tubular body formed by winding a plurality of strip-shaped veneers each having a wood grain extending in the width direction in a spiral shape and a laminated shape, and the strip-shaped single piece wound so as to be right-handed. A board,
When the strip-shaped single plate that is wound so as to be left-handed is mixed, it is possible to suppress the occurrence of twisting deformation when receiving a tensile load or a compressive load in the axial direction. Moreover,
There is no significant difference between the torsional strength when a torsional load in the left-hand twist direction is applied and the torsional strength when a twisting load in the right-hand twist direction is applied.

If the same number of strip-like veneers that are turned and strip-like veneers that are wound so as to be left-handed are alternately present, twisting deformation occurs when an axial tensile load or compressive load is applied. The effect of suppressing the above is more remarkable, and the difference between the torsional strength when a torsional load in the left-handed helix direction and the torsional strength when a torsional load in the right-hand helix direction is eliminated disappears.

来のものに比べて使用材料が少なくなる。When each strip-shaped veneer is provided with at least two or more reinforcing portions which are formed by sewing the thread with the sewing machine and extend in the lengthwise direction in parallel, the wooden tubular body is subjected to external force in various directions. Even when receiving the strip, breakage of the strip-shaped veneer in the longitudinal direction is prevented. Therefore, the strength of the wooden tubular body is improved. Moreover, since each strip-shaped veneer is simply provided with at least two or more reinforcing portions which are formed by sewing the thread with the sewing machine and extend in the lengthwise direction, the material used in comparison with the conventional ones. Is less.
