    摘要： A motor driven hydraulic tool including a portable battery is preferably employable for a cable laying operation. To displace a movable die toward and away from a stationary die, a piston is driven by pressurized hydraulic oil fed from a hydraulic pump section. The hydraulic pump section is operatively connected to a driving mechanism including a motor via a cam link mechanism. A plunger of the cam link mechanism includes a ring-shaped fitting portion which has an eccentric shaft fitted therein to rotate freely. The eccentric shaft is made integral with the rotational shaft of a motor for the driving mechanism.

    摘要： It is to provide a brush-equipped motor enabled to be used for a long time without performing operations and without interruption even when the brush wears out. When a rotor is caused to perform a turning operation, cam projections similarly start to perform a turning operation. Then, an abutting part, at which each of the cam projections contacts with a spring piece part of a corresponding one of the first brushes, gradually moves to an end of the first brush. Thus, the spring piece part of each of the first brushes is gradually and elastically deformed in a direction in which brush bodies come away from a commutator. When the turning operation continues still more, an end of each of the second brushes comes off a corresponding one of the cam projections, so that the brush bodies thereof contact with the surface of the commutator.

    摘要： A speed changing mechanism for use with an electric rotary tool, an electric press-attaching tool, an automatic screw tightening tool or the like, includes planet gears, a planet gear support plate integrally formed with an internal gear and provided with an external gear formed outwardly of the internal gear. The planet gears are rotatably supported by a second planet gear support plate mounted on a driven shaft and formed with a second external gear. The planet gears are engaged with the interanl gear and a sun gear provided on a one-way clutch. A cylindrical member having an internal gear is slidably fitted with at least one of the first and second external gears. The speed changing mechanism can be set to have a ratio of the rapid rotation speed to the slow rotation speed of 2.5/1 or less.

    摘要： A wheel for a wheelchair according to the present invention includes: an outer wheel or ring mounted on the inner periphery of a tire; an inner ring connected with a wheelchair frame (concentric with the outer ring and positioned inside the outer ring); a plurality of rolling elements interposed between the outer ring and the inner ring, arranged with an interval between each other in a circumferential direction; and a plurality of spacers (retainers or interval-holding members) for holding intervals between the rolling elements. Each spacer is in a shape extending along a circumferential direction of the outer ring and the inner ring, and is provided between the rolling elements respectively. The wheel does not have a hub and spokes, and the inner peripheral side does not rotate, and further the wheel weight is light. The wheelchair of the present invention includes the wheel for a wheelchair.

    摘要： A wheel for a wheelchair according to the present invention includes: an outer wheel 13 mounted on the inner periphery of a tire; an inner wheel 15 connected with a wheelchair frame 65 (concentric with the outer wheel 13 and positioned inside the outer wheel 13); a plurality of balls (rolling elements) 17 interposed between the outer wheel 13 and the inner wheel 15, arranged with an interval between each other in a circumferential direction; and a plurality of retainers (interval-holding members) 18 for holding intervals between the rolling elements 17. The retainer 18 is in a shape extending almost along a circumferential direction of the outer wheel 13 and the inner wheel 15, and is provided between the balls 17 respectively. The wheel does not have a hub and spokes, and the inner peripheral side does not rotate, and further the wheel weight is light.
