8. The clutch assist device of claim 1, wherein the rotatable member is generally in the form of a sector with a central angle smaller than 120° when viewed in the direction of the rotational axis.
wherein the angle formed between the first clutch wire and the second clutch wire, as the wires extend from the rotatable member, is not larger than 120°.
This application is based on and claims priority under 35 U.S.C. § 119(a)-(d) to Japanese Patent Application No. 2005-128070, filed Apr. 26, 2005, and to Japanese Patent Application No. 2005-002873, filed Jan. 7, 2005, the entire contents of which are hereby incorporated by reference.
The first rotatable member 57 has a pivot part 60 and a wire connecting part 61. As shown in FIG. 4, the first rotatable member 57 of the first embodiment has a lever part 62 having the cam groove 71 in addition to the wire connecting part 61. The rotatable member 57 of the second embodiment, however, does not have the lever part 62 and the wire connecting part 61 has a cam groove 71, as shown in FIG. 18. In this embodiment, since the lever part 62 is omitted, the area of the first rotatable member 57 is smaller. The first rotatable member 57 is generally in the form of a sector wits a central angle of smaller than 120° as viewed along the axial direction of the first pivot shaft 63. The shape of the first rotatable member 57 is not specifically limited, though. The first rotatable member 57 may have other shape as well, such as, for example, be triangular. The first rotatable member 57 may be made even smaller in size in some applications. For example, the first rotatable member 57, in the illustrated embodiment, is generally in the form of a sector with a central angle of less than 90°.
Also in this embodiment, the angle, which the first clutch wire 43 a and the second clutch wire 43 b make between each other, with the assist mechanism 52 interposed therebetween, preferably is between 90 and 120°. When the angle is equal to or smaller than 120°, the above-stated advantages of using the clutch assist device 50 to produce the directional change is notable. The angle of course may be greater than 120° though.
