摘要： PURPOSE: To diffuse a large quantity of exhaust gas bubbles at the periphery of blade parts and contrive to enhance starting accelerating property, by a method wherein an ON-OFF valve which is closed under the action of a centrifugal force of not smaller than a predetermined value is provided in a through- hole.
CONSTITUTION: At the time of a starting acceleration, a propeller 19 is rotated at a low speed, and a centrifugal force exerted on a valve body 30 is small, so that the propeller is maintained in the direction opposite to a valve seat 31 by an energizing force of a spring 32, and the through-hole 28 is maintained in a conducting state. Accordingly, a large quantity of an exhaust gas flows out to the outer peripheral part of a boss part 22 through an exhaust gas passage 26 and the through-hole 28, a large quantity of exhaust gas bubbles are diffused to the periphery of the blade parts 21, whereby the resisting force exerted from water to the propeller 19 at the time of the starting acceleration is reduced, and acceleration can be promoted. At the time of normal steaming, the through-hole 28 is maintained in a non-conducting state, whereby diffusion of exhaust gas bubbles to the periphery of the blade part 21 is eliminated, and an or iginally expected thrust can be obtained.

摘要翻译：目的：为了在叶片部件周围扩散大量排气气泡，提高起动加速性能，通过一种方法，其中在离心力不小于预定的离心力的作用下关闭的开关阀通孔中提供了数值。构成：在起动加速时，螺旋桨19以低速旋转，施加在阀体30上的离心力小，螺旋桨沿与阀座31相反的方向被维持在弹簧32的通电力，通孔28保持导通状态。因此，大量废气通过排气通路26和通孔28流出到凸台部22的外周部，大量的排气气泡扩散到叶片部的周围由此，在起动加速时从水施加到螺旋桨19的抵抗力降低，能够促进加速。在正常蒸汽时，通孔28保持在非导通状态，从而消除了排气气泡向叶片部分21的周边的扩散，并且可获得或预期的推力。

摘要： PURPOSE:To facilitate the rotation of a screw even when the salt is adhered by cutting the side of said screw into a plane such that a gap will exist between the screw hole of a cramp bracket at a portion of the outer face of a transom screw. CONSTITUTION:A transom screw 1 for fixing an outer-ship machine E to a transom 3 is fixed to the end of a cramp bracket 2. Both sides of said screw 1 are cut into planes to form the gaps 21, 22 between a screw hole 4 made in said bracket 2. Consequently even when the salt adhered to the screw, the salt can be pushed out through the gaps 21, 22 and exhausted upon the rotation of the screw resulting in the continuous rotation of the screw.

摘要： PURPOSE:To prevent the vibration of an outside-boat engine from being transmitted to the hull of a boat, by attaching the outside-boat engine with a connecting member having a buffer function, to a fitting bracket mounted on the hull. CONSTITUTION:An outside-boat engine 10 is mounted with a shaft 22a on a fitting bracket 22 vertically tiltably mounted on a stern board 21, so that the engine 10 can be swung right and left. A pair of coupling brackets 23, 23 secured on the upper and lower ends of the shaft 22a are connected to the engine 10 by a connecting member 30A. The connecting member 30A comprises an outer cylinder 31 made of synthetic resin, an inner cylinder made of a metal and located in the outer cylinder 31 concentrically therewith and an elastic member made of rubber and interposed between the outer cylinder 31 and the inner cylinder 32. The connecting member 30A absorbs the vibration of the outside-boat engine 10 enough to surely prevent the vibration from being trasnmitted to the fitting bracket 22.

摘要： PURPOSE:To prevent a ring gear, etc. from falling out of the outer periphery of a rotor by forcing in those members, such as ring gear, etc. around the outer periphery of the rotor, and by saliently providing the outer peripheral dred of the rotor meeting its lower end. CONSTITUTION:A step 7 is provided on the outer periphery of a rotor 1, and a ring gear 8 is forced in so as to bring it in contact with it. Besides, the other step 10 is provided on the outer periphery of the rotor 1, which is staked so as to saliently provide the outer peripheral part meeting the lower end of the ring gear 8 in order to form a slip-out preventing area 11. Thus, even if the ring gear 8, a weight ring, etc. are inadvertently rapped by a hammer, there is no case of having them fallen out of the outer periphery of the rotor 1, since the slip-out preventing part 11 is formed.

摘要： PURPOSE:To prevent the damage of a coupler of a boss of a cup of a flywheel by forming thinly the thickness of the intermediate part between the coupler and a permanent magnet holder, thereby suppressing the vibration produced at the holder side to be transmitted to the boss. CONSTITUTION:A boss 17 fixed to a crankshaft and a cup 18 which holds a permanent magnet 13 are integrated, for example, by a plastically coupling coupler 18, thereby forming a flywheel 12. In this case, the thickness of the intermediate part 23 between the coupler 19 and the part whitch holds the permanent magnet is formed thinly as compared with the thickness of the part which holds the permanent magnet 13, thereby isolating the flywheel 12 into the rigid boss 17 side and the cup 18 side. The boss 17 and the cup 18 may be coupled with rivets.
