PROBLEM TO BE SOLVED: To provide a caster device with a brake for a hand caster having such a structure in which rubbish, dust, water, etc. hardly penetrate a brake drum, maintenance of a brake mechanism of a brake is facilitated, simple application to wheels, yokes, etc. having different size is permitted and rich versatility is obtained.SOLUTION: A caster device with a brake for a hand caster includes a brake drum 51 fixed to a wheel 32, a cover drum 52, a brake mechanism 53 disposed on the inner surface side of the cover drum 52 and an actuation lever 4 which actuates the brake mechanism 53. Therein, the cover drum 52 is fitted to the brake drum 51 from the outer circumferential side and, moreover, is attached to the yoke 31 attachably and detachably, and the brake mechanism 53 includes a pair of brake shoes 68, brake lining 72 attached to the brake shoes 68, a brake spring 69 which always energizes the brake shoes 68 in such a direction as to close the brake shoes and a cam shaft which is pivotally attached to the cover drum 52 and can be rotated by the actuation lever.SELECTED DRAWING: Figure 5

    【課題】塵、埃、水等がブレーキドラム内に侵入しにくく、ブレーキの制動機構のメインテナンスがし易く、大きさの異なる車輪、ヨーク等に対しても簡単に適用可能な汎用性に富んだ構造の手押し運搬車用のブレーキ付きキャスタ装置を実現する。【解決手段】車輪32に固定されたブレーキドラム51と、カバードラム52と、カバードラム52の内面側に設けられた制動機構53と、制動機構53を作動させる作動レバー4と、を備えており、カバードラム52は、ブレーキドラム51に外周側から嵌合され、しかも、ヨーク31に着脱可能に取り付けられ、制動機構53は、一対のブレーキシュー68と、ブレーキシュー68に取り付けられたブレーキライニング72と、ブレーキシュー68を閉じる方向に常時付勢するブレーキバネ69と、カバードラム52に枢着され作動レバーで回転可能なカム軸と、を有する。【選択図】図5
