摘要： PROBLEM TO BE SOLVED: To enclose a gas with no risk of damaging a dust lip part. SOLUTION: A cap 52 equipped with a gas flow-path 58 to serve as a gas encapsulating path is previously mounted in a part of an oil seal 30 on the side with a dust lip part 40. This eliminates necessity for a part of a gas enclosing jig to be inserted between the dust lip part 40 and the periphery of a piston rod 16 against the energizing force of a spring 48 at the time of gas enclosure so that the dust lip 40 is precluded from being damaged. The cap 52 is removed from the oil seal 30 after enclosing of the gas.

摘要： PROBLEM TO BE SOLVED: To make a structure simple and improve workability in assembling. SOLUTION: An oil seal lip 30 is mounted on a metal ring 28 and a lip part 42 for sealing a gas sealing passage 26 is integrated with it, thereby sealing the gas sealing passage 26 only by pressing down the metal ring 28 with an oil seal pressing jig 52. Therefore a process for mounting an O-ring alone is not required compared with the case where the lip part 42 comprises a different member such as an O-ring or the like, which improves workability in assembling the oil seal part and a shock absorber 10. Since a different member such as the O-ring or the like is eliminated, the number of parts is reduced and the structure is made simple.

摘要： PROBLEM TO BE SOLVED: To provide a shaft seal equipped with a dust lip excellent in dust resistance.SOLUTION: The shaft seal 200 includes a reinforcing ring 210 and a seal part 220. The seal part 220 includes an oil lip 230 and the dust lip 240. The dust lip 240 has a tip protruded toward the outer peripheral face of a shaft to prevent dust from entering from the atmosphere. In the dust lip 240, a reinforcing material 300 inferior in rigidity to the reinforcing ring 210 exists to prevent temporal deterioration of the dust lip 240, thus preventing reduction in dust resistance of the dust lip 240.

摘要： PROBLEM TO BE SOLVED: To suppress damage to a starter motor when a vehicle moves backward with the engine being stalled due to an operation failure of a clutch or the like on a climbing road, in a control device for a vehicle equipped with a constant mesh-type starter and a manual transmission.
SOLUTION: The control device includes an inclination sensor for detecting an angle of inclination in a fore-and-aft direction of a vehicle, a vehicle speed sensor for detecting a speed of the vehicle, a shift position sensor for detecting a shift range position, and an ECU. When the shift range position detected by the shift position sensor is at a forward gear position other than the first gear (ST1: NO), the angle of inclination of the vehicle detected by the inclination sensor is greater than 0° (ST2: YES), and a retreat speed of the vehicle detected by the vehicle speed sensor is greater than 0 km/h (ST3: YES), the ECU causes the engine to stall (ST4).
