A drive device includes a plurality of gears; and a grease composition that is held on a tooth flank of at least one gear of the gears. The at least one gear is made of a resin. The grease composition contains a hydrocarbon base oil, lithium soap serving as a thickener, and olefin resin powder. A weight ratio between the hydrocarbon base oil and the lithium soap in the grease composition is in a range of 94.5:5.5 to 96.0:4.0. A consistency of the grease composition is in a range of 360 to 400.
摘要:
A drive system includes multiple vibrating members that tend to vibrate when these members are driven and a holding system to hold the multiple vibrating members. The holding system at least includes a first holding unit and a second holding unit superimposed on and partially connected to each other. The multiple vibrating members include a first vibrating member and a second vibrating member. The first vibrating member is held by the first holding unit and is not held by the second holding unit. The second vibrating member is held by the second holding unit and is not held by the first holding unit. At least one of the first vibrating member and the second vibrating member is a driving device to drive another member as a drive source.

A sheet feeder is provided. The sheet feeder includes a sheet container installation space forming member to form a sheet container installation space in the sheet feeder; a sheet container to contain a recording sheet therein, which can be inserted into or extracted from the sheet container installation space; and a sheet feeding device, which contacts with the recording sheet in the sheet container at a sheet pickup position to apply a feeding power to the recording sheet. The sheet feeder has a passage, which is formed by the sheet container and the sheet container installation space forming member to communicate the inside of the sheet feeder with the outside thereof and which is detoured plural times, wherein the passage is located above the sheet pickup position.

A driving device includes: a plurality of vibrating members that vibrate when the vibrating members are driven; and a holding part that holds the vibrating members. The holding part includes a first member with which one or more of the vibrating members are brought into contact, and a second member with which one or more of the vibrating members are brought into contact. The first member and the second member are partially coupled to each other. A grounding member for electrically grounding a member held by the holding part is brought into contact with one of the first member and the second member that is more difficult to vibrate.

A pneumatic tire with a side wall portion includes a decorative region including two or more decorative portions that are continuously disposed so as to be contiguous in a tire circumferential direction and the tire radial direction, the decorative portions including multiple convex ridges that are disposed on an outer surface so as to be adjacent in the tire circumferential direction. A ridge arrangement angle is the same in the same decorative portion, and a ridge arrangement angle of the contiguous decorative portion differs therefrom. A distance between a first imaginary boundary line joining end portions of the ridges of the decorative portion that are on a side adjacent to the contiguous decorative portion and a second imaginary boundary line joining end portions of the ridges of the contiguous decorative portion on a side adjacent to the first imaginary boundary line is less than 1 mm.
