Suction pad
A suction pad configured to suck and hold a fruit includes a pad main body made from an elastically deformable member and having a held base end portion; a hollow formed inside the pad main body so as to extend from a base end side to a tip end side; and a hole configured to communicate with the hollow and being open to a tip end portion of the pad main body, and an opening diameter of the suction hole is smaller than an inner diameter of the hollow.
1 . A suction pad for sucking and holding an object, the suction pad comprising:
a pad main body that is made from an elastically deformable member and has a held base end portion;
a hollow that is formed inside the pad main body so as to extend from a base end side to a tip end side; and
a suction hole that is configured to communicate with the hollow and is open to a tip end portion of the pad main body,
wherein an opening diameter of the suction hole is smaller than an inner diameter of the hollow.
2 . The suction pad according to claim 1 , wherein the tip end portion of the pad main body is elastically deformable.
3 . The suction pad according to claim 2 , wherein the tip end portion of the pad main body is thinner than the held base end portion.
4 . The suction pad according to claim 1 , wherein the elastically deformable member includes a sponge.
5 . The suction pad according to claim 4 , wherein the pad main body includes the tip end portion made from a sponge having open cells and the held base end portion made from a sponge having closed cells.
6 . The suction pad according to claim 1 , wherein the pad main body includes, at the tip end portion, a tapered portion in which an inner diameter of the hollow decreases from the base end side toward the tip end side.
7 . The suction pad according to claim 6 , wherein the tapered portion is thinner on the tip end side than on the base end side.
