Abstract: In a tensioner in which a tension rod advances from the casing to apply a tension to a chain or timing belt, the advancement of the rod is locked by inserting a pin into a penetrated hole formed at the drawing out portion of the rod. The penetrated hole is sealed to prevent the loss of lubricating oil when the pin is removed.

Abstract: A clamp includes a metal band body. The band body has separated both ends. The ring-shaped band body includes an outer lap portion, an inner lap portion, and an intermediate portion located between the inner and outer lap portions. A retaining hole is formed in the outer lap portion, and a hook is formed on the inner lap portion. The hook includes a sliding surface for allowing sliding of the outer lap portion when the outer and inner lap portions are relatively moved in a direction for reducing the diameter of the band body, and a hook edge hooked by an edge of the retaining hole against a force for increasing the diameter of the band body. A first projection is formed at the end of the outer lap portion to hook the distal end of a first arm of a crimping tool. A second projection is formed on the intermediate portion of the band body to hook the distal end of the second arm of the crimping tool. A distance between the first and second projections is shorter than that between the distal ends of the open arms of the crimping tool.

Abstract: A roller shade comprising a spring-loaded retractor, a screen sheet having a trailing edge connected to the retractor, and a rod member attached to a leading edge of the screen sheet. The two ends of the rod member are guided by a pair of guide rails so that the rod member may be moved toward and away from the retractor by using a power drive unit in such a manner that the screen sheet may be paid out from the retractor and extended against the spring force acting on the retractor, and retracted or wound around the retractor, as desired. The rod member incorporates therein a telescopic structure which allows its length to be varied according to the change in the distance between the guide rails as the rod member is moved toward and away from the retractor. Thus, the roller shade can be adapted to windshields, windows or other openings having trapezoidal, curved or other non-rectangular shapes.

Abstract: In a slow-acting rotary shaft device, a shaft, which rotatably supports a second member, includes a hollow shaft body latched to a first member inrotatably, a cap member outwardly inserted on an end portion of the shaft body rotatably and latched to the second member inrotatably, a torsion bar which has one end latched with the shaft body and another end latched with a cap member, and a viscous grease enclosed between the shaft body and cap members. The hollow shaft body is divided into two portions, a body portion of which latches to one of the end portions of the torsion bar. In opposite surfaces of the two portions, a projection formed at one surface and a concave portion formed at another surface are loosely inserted and provided with a relatively rotatable race area. When this device is used, the rotative member is rotated at a slow speed by a jumping up torque of the torsion bar in a rotation area up to a neutral point, while in a rotation area past the neutral point, the rotative member can be stopped at any position.
