The control wire is fixed to the saver arm, and a saver spring is interposed between the saver arm and the linkage machanism, the saver arm includes a spring urging portion which deflects the saver spring when the saver arm swings forwardly and backwardly and applies to the saver arm a spring reaction to restore a saver arm in the direction opposite to the swinging direction thereof.

Abstract: An operating force transmission device for a brake which transmits an input operating force applied to a brake lever to operating members of the brake through a control cable formed of an inner wire disposed within an outer sheath and interconnecting the brake. The device includes a housing, a receiving member supported movably relative to the housing and adapted to retain thereto one of the inner wire and the outer sheath of the control cable. A control spring is provided for deflecting in response to a braking force output of the operating members of the brake in excess of a predetermined magnitude to enable the receiving member to move relative to the housing when the predetermined braking force output magnitude is exceeded. This reduces the magnitude of a further braking force output of the operating members of the brake with respect to the magnitude of the input operating force applied to the brake lever and transmitted to the operating members of the brake.

A pawl control member is supported rotatably relative to the driving shaft and includes an impeding portion to impede the retaining pawl from engagement with the anti-reverse rotation gear and an engagement-allowing portion for allowing the retaining pawl to engage with the anti-reverse rotation gear. The pawl control member rotates substantially in concert with the driving shaft during at least a portion of a complete revolution of the driving shaft.

Abstract: A speed-change operating device for a bicycle includes an operating lever for actuating a derailleur, the operating lever being supported rotatably through a lever shaft to a base member attached to the bicycle frame. A friction mechanism applies to the lever an adjustable rotational resistance against a bias force of a return spring associated with the derailleur. A positioning mechanism includes a positioning member having a plurality of engaging portions for precisely setting the respective speed change stages of the derailleur and an engaging member engageable with at least one of the engaging portions. An operating mechanism selects between an operating mode and a non-operating mode of the positioning mechanism so that the positioning mechanism can be placed in a non-operating mode, when desired, with the speed-change operation being performed in such non-operating mode only with the friction mechanism resisting the return spring.

Abstract: A caliper brake for a bicycle which includes a pair of fixing bases, brake arms including respective brake shoes and bosses, and return springs, wherein the boss of each brake arm is provided with a cavity in which the return spring is housed. A spring holder for each return spring is rotatably mounted with respect to the associated brake arm boss. Since the relative rotation of the spring holder with respect to the boss is regulated in a predetermined range, the return spring is given a preload, and the spring holder is fixed to the fixing base, each brake arm can be easily assembled with the fixing base.

Abstract: A protective device for a driving chain stretched across a front gear and a rear gear of at a bicycle, which forms a guard body inserted below a driving side path of the chain at the driving side of the chain travelling from the rear gear to the front gear and having a chain guide surface for guiding axially outwardly part of the chain on the driving side path with respect to a rear bicycle wheel, the guard body is mounted on the bicycle frame through a mounting member, so that, even when the chain vibrates due to a bounce of the bicycle while running, the chain is prevented from contacting the rear wheel to be carried along with the rotation of the rear wheel.

Abstract: A front derailleur for a bicycle which includes a linkage mechanism which is formed of a fixing member, a chain guide and a pair of linkage members. Four pivot shafts connect the linkage members with the fixing member and the chain guide and have axes which are slanted forwardly from a perpendicular plane through a center line between the guide plates the fore ends of the pivot shafts are positioned farther than their rear ends from the chain guide. When the linkage mechanism is deformed, the chain guide is moved axially of the multistage front gears and obliguely longitudinally of the bicycle, thereby improving the speed change characteristics and speed control efficiency of the derailleur.

The linkage device supports the chain guide to the fixing member so that the chain guide is movable axially with respect to the gear assembly. The linkage device has one end pivotably supported to the fixing member by a first pivot shaft and another end pivotably supported to the chain guide by a second pivot shaft.

Abstract: A drag adjusting device for a closed-face type fishing reel is provided which has a spool rotatably supported at the front of a reel body, a mounting leg below the spool, a brake plate provided between the spool and the reel body and a drag actuating plate extending at both ends radially of the spool for urging the brake plate in one direction to apply a braking force to the spool. A drag setting thumb nut is operatively engaged with one lengthwise end of the drag actuating plate to change the position thereof with respect to the spool in order ot set the braking force to be applied to the spool. An adjusting member in operative engagement with the other lengthwise end of the drag actuating plate adjusts the braking force set by the setting thumb nut.

Abstract: A fishing line guide device is provided for a fishing reel. The guide device includes a tubular guide shaft, a level wind shaft having traverse grooves, and a fishing line guide which includes an outer guide member supported to the guide shaft such that it is axially movable in reciprocation thereon and an inner guide member supported to the level wind shaft such that it is axially movable in reciprocation thereon. Both guide members are coupled with each other so that they are non-rotatable with respect to the guide shaft and level wind shaft respectively. The inner guide member holds a slider having an engaging projection engageable with the traverse grooves.

Abstract: A brake lining for a fishing reel includes a metal or synthetic resin flexible, heat-resistant base layer and a woven fabric layer formed of heat resistant fibre and bonded onto at least one side of the base layer. The brake lining is applied to a friction member, such as a drag disc, forming part of a drag mechanism of the fishing reel so that the brake lining is brought into full-face contact rather than local contact with the friction member. The synthetic resin material of the base layer does not impregnate the woven fabric layer. As a result, none of the synthetic resin material is exposed on the outside surface of the woven fabric layer.

Abstract: A cantilever brake is provided at the upper portion of each brake shoe with a swollen portion swollen slantwise or obliquely upwardly and away from the upper edge of the braking surface of the break shoe toward a shoe holder holding the brake shoe, to thereby prevent reduction in the braking surface caused by wearing of the brake shoe.
