Hose clamp structure and working machine

A hose clamp structure, comprising:

• a vertical plate having an opening;
• a groove portion provided at a back side of the vertical plate on one of opposite sides of the opening in a plate-surface parallel direction such that the groove portion is adjacent to the opening, the groove portion being open toward the opening in the plate-surface parallel direction;
• a receiver portion provided at the back side of the vertical plate on the other of the opposite sides of the opening in the plate-surface parallel direction;
• a first clamping member to be inserted in the groove portion;
• a second clamping member made of an elastic member and configured such that the second clamping member is placed in the receiver portion through the opening from a front side of the vertical plate to contact the receiver portion with the first clamping member being inserted in the groove portion and such that at least one hose passing through the opening is held between the first clamping member and the second clamping member;
• and
• a pressing member to be attached to the vertical plate to press the second clamping member from the front side of the vertical plate to elastically deform the second clamping member to cause the second clamping member to press the first clamping member;
• wherein
• the first clamping member has a thickness substantially equal to a groove width of the groove portion;
• the second clamping member has a thickness such that the second clamping member protrudes forward through a back surface of the vertical plate via the opening when the second clamping member is in contact with the receiver portion but is not pressed by the pressing member;
• and
• the pressing member includes a main plate to be inserted in the opening to press the second clamping member, and an attachment plate fixed to the main plate to contact a front surface of the vertical plate and attached to the vertical plate.

• a pressing member to be attached to the vertical plate to press the second clamping member from the front side of the vertical plate to elastically deform the second clamping member to cause the second clamping member to press the first clamping member;
• wherein the vertical plate has an insertion groove extending from an outer edge of the vertical plate toward the opening to communicate with the opening and configured to allow the at least one hose to pass through the insertion groove in a direction perpendicular to a longitudinal direction of the at least one hose.
