  Next, operations and effects when the cared person gets on the transfer support apparatus 1 will be described.

  As shown in FIG. 2, when the cared person gets into the transfer support apparatus 1, the cared person is in the sitting position. When the body holder 13 is brought into contact with the cared person, the position of the iliac pad 42 is adjusted in advance by operating the vertical movement unit 43. Thereby, the body holder 13 is in a state where the cared person's sternum contacts the front chest pad 41 and the iliac contacts the iliac pad 42.

  Here, the chest front pad 41 is formed with a first relief portion 41d. Therefore, when a woman uses the transfer assisting apparatus 1, the chest part enters the first escape portion 41d, so that the body can be brought into close contact with the chest front pad 41 without being compressed. .

  Further, the body holder 13 is formed with a second escape portion 44 surrounded by the front chest pad 41, the iliac pad 42, and the up-and-down operation portion 43 as a space in which the sphere can be accommodated. Therefore, the abdomen enters the second escape portion 44 when the cared person of the body type with the abdomen protruding uses the transfer support device 1. Thereby, there is nothing to compress the abdomen of the cared person from the front, the occurrence of pain in the abdomen can be suppressed, and the iliac pad 42 can be supported by the iliac pad 42.

  As shown in FIG. 7, by operating the operation part provided in the cart part 11, the angle and position of the arm part 12 and the body holder 13 are changed, and the cared person is lifted. At this time, if the cared person is in a standing position and the back muscles are stretched, the position of the iliac is shifted downward. Here, the iliac pad 42 slides downward in accordance with the movement of the iliac as the up and down operation unit 43 operates. Thereby, the iliac pad 42 maintains the state contact | abutted by the care receiver's iliac bone.

  As shown in FIG. 8, when the iliac pad 42 is fixed, when the cared person is lifted and is in the standing position, the back muscles are stretched so that the iliac is displaced from the position of the iliac pad 42. A fall occurs and the iliac pad 42 bites into the abdomen. As a result, the iliac pad 42 may press the abdomen and cause pain in the care recipient. Furthermore, when the iliac pad 42 is detached from the iliac, the front chest pad 41 is easily displaced. Further, if the lifting is continued in this state, there is a possibility that the heel is pressed against the rib cage holding pad 32 to cause pain and dislocation of the shoulder.

  On the other hand, since the iliac pad 42 slides as shown in FIG. 7 and maintains the state of being in contact with the care recipient's iliac, the pressing load of each pad does not change. The entire sliding is suppressed, and the generation of pain to the care recipient can be suppressed.

  As described above, in the transfer support device 1, the protruding portions such as the cared person's chest and head are released to the first escape part 41 d of the chest front pad 41, and the cared person's abdomen is transferred to the second escape part 44. Relief can be lifted without pressing the cared person's chest and abdomen. In addition, the occurrence of slipping of the cared person from the transfer assist device 1 is suppressed, and the occurrence of pain due to slipping is suppressed.

  Note that the present invention is not limited to the above-described embodiment, and can be changed as appropriate without departing from the spirit of the present invention.
