Abstract: A tension fluctuation alleviating device, for use in a fabric printing apparatus including a fabric supplying device, a printing mechanism, a guide between the fabric supplying device and the printing mechanism, and a fabric take-up device, the fabric printing apparatus configured to perform printing on the fabric while intermittently sending the fabric to the printing mechanism, includes a support member provided between the fabric supplying device and the guide device and extending across a width direction of the fabric, and a tension relieving member including an elastically deformable elastic portion supported by the support member and extending from the support member toward the fabric, and a contacting portion closer to the fabric than the elastic portion and contacting with the fabric.

Abstract: A printing method is performed by use of a printing device. The printing device includes a print head, a supply roll, a serving roll, a support roll, a feed roll, and a winding roll. The printing device feeds a fabric material toward the winding roll by a prescribed length each time that a cycle of a print operation is performed by the print head, so that the printing is performed on the fabric material intermittently. The printing method includes performing a first feed operation of intermittently rotating the feed roll by a first motor to pull the fabric material from a print unit and feed the fabric material toward the winding roll by a prescribed length; and performing a second feed operation of intermittingly rotating the serving roll by a second motor to feed the fabric material toward the print unit.

Abstract: A crank bearing is disclosed that includes a semicircular upper bearing and a semicircular lower bearing, which can be split from each other. The upper bearing includes a first oil passage for introducing engine oil from the outside to a gap between the crank bearing and a crank journal, and a second oil passage for permitting the engine oil to flow in the circumferential direction of the crank bearing. The first oil passage includes an inner circumference opening, which is open to the inner circumference of the main bearing. The upper bearing includes a non-undercut portion in which no oil passage is formed on the trailing side of the inner circumference opening in the rotational direction of the crank journal.

Abstract: A bearing (crank bearing 6) is constituted of an upper bearing (61) that is attached to a cylinder block, a lower bearing (67) that is attached to a crank cap, and a bearing filter (71) for filtering engine oil. The bearing filter (71) is fitted in an oil hole (62A) of the upper bearing (61).
