PROBLEM TO BE SOLVED: To provide a chair type massage device which enables any users to appropriately massage his/her calf, ankle, sole, or the like irrespective of individual differences in the lower thighs by displacing a leg rest part by adjusting to a position where a user needs a massage in the calf while extending and displacing a foot rest in accordance with a length of the lower thigh.SOLUTION: The chair type massage device includes a backrest 4, a seat part 2, the leg rest part 5, a base frame 27 for supporting the leg rest part 5, and the foot rest 6. First and second expanding/contracting mechanisms for operating to expand and contract the leg rest part 5 and the foot rest 6 are provided between the leg rest part 5 and the base frame 27 and between the foot rest 6 and the base frame 27. The first expanding/contracting mechanism is constituted by a first guide structure provided between a frame 18 of the leg rest part 5 and the base frame 27, and a frame driving structure using a motor 53 as a driving source. The second expanding/contracting mechanism is constituted by a second guide structure provided between a frame 22 of the foot rest 6 and the base frame 27, and a spring 61 for biasing to return the frame 22 to an extending standby position.COPYRIGHT: (C)2013,JPO&INPIT【課題】足台を下腿の長さに応じて伸長変位させながら、脚載部をふくらはぎのマッサージしたい位置に適合して変位でき、下腿の個人差とは無関係に誰でもがふくらはぎ、くるぶし、足裏などのマッサージを好適に行なえる椅子式のマッサージ装置を提供する。【解決手段】背もたれ4と、座部2と、脚載部5と、脚載部5を支持するベース枠27と、足台6を備えている。脚載部5とべース枠27との間、足台6とべース枠27との間に、脚載部5および足台6を伸縮操作する第1・第2の伸縮機構を設ける。第1伸縮機構は、脚載部5のフレーム18とべース枠27との間に設けられる第1ガイド構造と、モーター53を駆動源とするフレーム駆動構造とで構成する。第2伸縮機構は、足台6の台枠22とべース枠27との間に設けられる第2ガイド構造と、台枠22を伸長待機位置へ向かって復帰付勢するばね61とで構成する。【選択図】図1
