A disc brake caliper is basically provided with a single main body and an end cap. The single main body includes a hydraulic cylinder bore partially defining a hydraulic chamber having a cylinder axis and an end bore disposed along the cylinder axis. The end cap is coupled to the single main body in the end bore so as to close the hydraulic chamber. The end cap has an exterior surface that is free of a tool engagement structure.

An electrical bicycle derailleur includes a base member and a movable member movably arranged between a retracted position and an extended position. A linkage operatively couples the movable member to the base member. The linkage includes a first link member and a second link member. The first link member is disposed closer to the base member than the second link member. A motor unit is operatively coupled to the first and second link members to rotate the first and second link members. A linkage housing is configured to support the first and second link members and the motor unit. A first diameter of the first link member is different from a second diameter of the second link member and/or a first tooth number of the first link member is different from a second tooth number of the second link member.

A keyboard including a plurality of keys, a baseplate which supports each of the keys, and a frame which is arranged to stand substantially perpendicularly to the baseplate and to surround the each of the keys, in which the each of the keys includes an keycap configured to be depressed, the keycap including a keycap top end which constitutes a top end of the keycap and a keycap sidewall which hangs down from an edge of the keycap top end to the baseplate, and in which the baseplate has a hole arranged at a site that corresponds to a bottom end of the keycap sidewall, the hole configured to insert the bottom end of the keycap sidewall therein from above, and in which, when the keycap is in a depressed state, the bottom end of the keycap sidewall is inserted into the hole.

Mounted between bottom and top surfaces of a case are: second buffer materials and first buffer materials brought in surface contact with a bottom surface of a hard disk drive (HDD) via an insulating member, and upper buffer materials brought in surface contact with the opposite side of the HDD via the insulating member. When impact Fis applied to the HDD, the second buffer materials contract from a thickness of Tto T, and the first buffer materials buckle. Buckling parts of the first buffer materials buckle when the second buffer materials contract to thickness T, and can achieve impact-lessening independently from the second buffer materials. The second buffer materials contract singly from Tto equal Tto or more than T, whereas the first buffer materials and second buffer materials both act at thickness Tor beyond. Therefore, impact-lessening can be achieved in a broad range.

A slit openingis formed on a lower principal surfaceof a hard disk case, in the vicinity of the inner side of an angle part formed by a lower left lateral walland an opposing lower lateral wall. A hard disk driveis placed in the hard disk case. When the hard disk driveis subjected to vibration caused by disturbance on the hard disk case, elastic deformation of an angle partof the slit openingoccurs using an axisas a center to reduce vibration of the hard disk drive. Thus, it is possible to reduce the thickness of the hard disk case. With such a configuration, a hard disk case that is for housing an electronic component and that can have a small thickness can be provided.
