摘要:
A water protecting cap used for a distributor, which is to distribute ignition voltage in an internal combustion engine, with the object of preventing water from coming into the interior of a casing of the distributor through a ventilation opening formed in the casing. The cap is composed of a body portion to be crowned on a tower portion embracing the ventilation opening therein and a tongue portion integrally formed with the former. Between the body portion and the tongue portion a sheltered space is confined, which is protected from water spray which might come to the inside of the engine room of a vehicle. A ventilation passage formed through the cap body portion for being communicated to the ventilation opening is opened at the other end thereof at a position innermostly located in the sheltered space.

A damper structure for a gear device includes a first gear (2) mounted to turn with respect to a shaft (1) in a circumferential direction, a second gear (3) mounted on the shaft (1) to rotate integrally, a stopper rubber (33) mounted on the second gear (3) to face the first gear (2), and a pressing protrusion (24) at the first gear (2) to face the second gear (3). The stopper rubber (33) is configured to be elastically deformed by pressing the pressing protrusion (24) in a circumferential direction of the second gear (3) during rotation of the first gear (2) and be restored to the initial shape by separating the pressing protrusion (24) during stop of the first gear (2). A recess (25) for accumulating lubricating oil in the first gear (2) is formed to face the stopper rubber (33).
