摘要： PROBLEM TO BE SOLVED: To improve strength by covering a metal sheet with a longitudinal shape on the longitudinal face in the length direction of a prismatic wood provided on the outside plate face of a concrete placing form plate. SOLUTION: A metal sheet 2 with a longitudinal shape is covered on one or two opposite longitudinal faces in the length direction of a prismatic wood 1 to form a concrete placing form support member. The metal sheet 2 is formed into a nearly U-shaped cross section and covered on the wood 1 in the hooked state, and it is fixed to the wood 1 by fixing members such as nails via fitting holes 6. The wood fitting section of the wood 1 where no metal sheet 2 is covered is kept in contact with a form plate 7, and the wood 1 is fitted to the form plate 7 by nails. The concrete placing form support member can be prevented from being ruptured or broken when a form is demolished, it can be repeatedly used, the incineration, disposal, and consumption of a large quantity can be prevented, and the cost can be reduced.

摘要： PURPOSE:To provide a ski board with which even a biginner can freely control it as intended by applying various loads to the descending board by enlarging the degree of freedom for a human being at the time of operation. CONSTITUTION:This ski board is constituted by forming a smoothly curved part 1a at the front part of a wide board 1 and freely turnably pivotally attaching a pole 3 equipped with a handle 2 at the upper end part of the curved part 1a. Sometimes, the smooth cowling of half shell structure is provided at the front part of the wide board in place of the curved part 1a. Further, the pole 3 is sometimes freely turnably pivotally attached a little forward rather than the central part of the wide board.

摘要： PURPOSE:To prevent reduction in output an engine and generation of trouble upon start-up by setting that exhaust gas is flowed vortically with spontaneousness by a guide vane, and made to take a U-turn after it collides onto the rear wall surface of an expansion chamber, then led out from a leading outlet through a noise reduction chamber. CONSTITUTION:In a partition cover cylinder 36, a noise reduction chamber (b) is formed partitively inside an expansion chamber (a), and thereby exhaust gas which is accelerated and dispersed by a guide vane 29 is prevented from flowing-in directly insides of the second and third punching metals 31, 33 and the second sound absorption material 34 firstly until exhaust gas collides on the rear wall surface of the expansion chamber (a). By making exhaust gas collide onto the rear wall surface of the expansion chamber (a) it enables exhaust gas which is changed directionally in a U turn manner to flow more smoothly from the back into the second and third punching metals 31, 33. It is thus possible to reduce pressure of exhaust gas and improve performance of noise reduction.

摘要： PURPOSE:To improve steering performance in relation to rapid control, by a method wherein a pair of handle grips are vertically mounted to end parts on both sides of a handle bar situated to the upper part of a handle post standing upright from a boat body in a manner that the hand grips are rotatable in a longitudinal direction centering around the axis of the bar. CONSTITUTION:In a title small boat, one driver rides, in a standing-up state, on a floor deck 11 of a boat body 10, and through turn control of a handle bar 17 gripped by hands, a steering cable wired from a hand post 13 to the interior of the boat body 10 is controlled. This control causes lateral swing of the steering nozzle of a jet jet propulsion device to provide steering motion. In this case, a pair of handle grips 26 are mounted to the end parts on both sides of the handle bar 17, being long in the direction of the width of the boat, so that the grips stands upright on a plane crossing an installation plane X-X of the bar 27 at right angles, the grip is rotated in a longitudinal direction centering around the longitudinal axis of the bar 17, and a rise and fall angle thetawith the plane X-X is regulatable.
