Abstract: A multiple wheel vehicle according to the present invention enables to incline freely the two wheels together with the vehicle body while keeping the ground contacting pressures of the two wheels equal. The multiple wheel vehicle comprises a pair of swinging arms 4 each comprising one-side end portion supported pivotably with right and left support shaft portions 3A and an interlocking device 6 for interlocking them alternately up-and-down. The interlocking device 6 comprises a pair of tilted members 17, a divertible member 19, and a cord-like body 20 connecting them. Each of the tilted members 17 comprises a first circular surface part 21 that has a center of a circular arc as a shaft center 3i of the support shaft portion 3A, and tiltably supported integrally with the swinging arm 4.

Abstract: A bicycle with two front wheels includes: a main frame provided at its front end with a vertically oriented head tube; a pair of front wheels non-rotatably provided on both ends of a front wheel shaft held below the head tube; a rear wheel that is rotatably supported by a rear end of the main frame; driving means for driving the front wheels; and steering means for steering the front wheels. The steering means includes a steering handle, and a steering shaft extending from the steering handle downward and including a vertical steering shaft portion that is rotatably supported by the head tube and that has a lower end for turning the front wheel shaft. The driving means includes a horizontal driving shaft pivotally supported by the main frame, and a vertical driving body that can be rotated by the horizontal driving shaft and that is coaxial with the head tube, and the vertical driving body rotates the front wheel shaft through driving-interconnection means.

Abstract: A bicycle comprising a longitudinally extending frame, a front wheel disposed at the front of the frame, a rear wheel disposed at the rear thereof, and first and second auxiliary supporting devices disposed on each side of the rear wheel, each of the auxiliary supporting devices including an arm that has one end pivoted to the frame and the other end vertically movable as a free end and that can rotate independently of each other, an auxiliary wheel for assisting traveling of the bicycle pivotally supported parallel with the rear wheel, a spring for energizing the arm in a rotating direction such that the auxiliary wheel moves downward, and a disc rotor which can be locked to restrict the rotation of the arm to thereby fix the vertical movement of the auxiliary wheel when stopping at a red light.

Abstract: A bicycle comprising a longitudinally extending frame, a front wheel for steering disposed at the front of the frame, a rear wheel disposed at the rear thereof, and auxiliary wheels for assisting the traveling of the bicycle. The bicycle further comprises an auxiliary wheels for assisting the traveling of the bicycle. The bicycle further comprises an auxiliary means having first and second auxiliary supporting devices disposed on one side and the other side of the rear wheel. Each of the auxiliary supporting devices includes an arm having one end pivotally supported on the frame and the other free end movable in the vertical direction, an auxiliary wheel pivotally supported parallel with the rear wheel, an energizing means for energizing the arm in the rotating direction the auxiliary wheel moves downward, and an arm lock means securing the arm.

Abstract: An applicator for applying various kinds of paint, liquid adhesives and the like to a surface in such a way that they are spread evenly and uniformly on the surface. The applicator possesses a cylindrical member which has an applicating liquid reservoir formed in it and a conduit to carry the applicating liquid from the outside into the applicating liquid reservoir, and internally apply pressure on a resilient closure which maintains a slit normally closed, such internal pressure causes the slit to open along its entire length when the internal pressure of the applicating liquid in the applicating liquid reservoir is more than a predetermined level. The cylindrical member is designed in such a way that the slit opens equally along its entire length.
